Background: The radiological and surgical anatomy of the frontal sinus should be well-known in all age groups to successfully manage frontal sinus diseases and reduce the risk of complications in sinus surgery. Purpose: To define frontal sinus and frontal cells according to the International Frontal Sinus Anatomy Classification (IFAC) criteria in pediatrics and adults. Material and Methods: A total of 320 frontal recess regions of 160 individuals (80 pediatric, 80 adults) who underwent a computed tomography (CT) scan of the paranasal sinus (PNS) were included in the study. Agger nasi cells, supra agger cells, supra agger frontal cells, suprabullar cells, suprabullar frontal cells, supraorbital ethmoid cells, and frontal septal cells were evaluated in the CT analysis. Results: The incidence rates of the investigated cells were determined to be 93.1%, 41.9%, 60.0%, 76.3%, 58.5%, 18.8%, and 0% in the pediatric group, respectively, and 86.3%, 35.0%, 44.4%, 54.4%, 46.9%, 19.4%, and 3.4% in the adult group, respectively. Considering the unilateral and bilateral incidence of the cells, agger nasi cells were highly observed bilaterally in both the pediatric group (89.87%) and the adult group (86.48%). Conclusion: Our study results show that IFAC can be used as a guide to increase the chance of surgical treatment in the pediatric and adult groups and that the prevalence of frontal cells can be determined radiologically and contributes to the generation of estimations of the prevalence of frontal cells.

ankle magnetic resonans imaging ,Infrapatellar cyst - Abstract
Aim The infrapatellar fat pad is one of the fat pads of the knee and is particularly important for knee movements. The volume and shape of this fat pad varies individually and can be affected by a variety of tumor and tumor-like pathologies. Cystic structures, which are extremely common in and around the knee joint, can cause various symptoms, especially pain. Materials and Methods 69 knee MRI examinations performed in our center between October 2021 and December 2021 were included in the study. Presence, localization, contours and intensities of infrapatellar cysts and whether there is a compression effect on neighboring structures were investigated in MR images. Results The mean age of 69 subjects (41 females, 29 males) included in the study was 53.471±15.23 (52.08±17.375 in females, 58±3.367 in males). Findings of infrapatellar cysts were found in 17 (24.64%) of 69 patients. Of the detected infrapatellar cysts, 13 (76.5%) were in the posterior position and 4 (23.5%) were in the anterior position. While the cyst was in the lateral position in 14 (82.4%) patients, it was medial in 3 (17.6%) patients. While 16 (94.1%) patients with cysts in the inferior position were detected, 1 (5.9%) patient was observed in the superior position. According to the analysis results of spatial data, infrapatellar cysts are most commonly located posterior, lateral and inferior. The mean volume of the detected cysts was found to be 773.91±700.73 mm3. Cysts with smooth surface were observed in 12 (70.59%) patients and with lobulated contours in 5 (29.41%) patients. None of the cystic structures showed a compression effect. Finally, when the intensity structure of the cyst is examined, it has a homogeneous cystic appearance in 16 (94.12%) patients, while it has soft tissue intensity in 1 (5.88%) patient. Conclusion Cystic structures within the infrapatellar fat pad are not as rare as previously reported in the literature. Infrapatellar cysts, which are usually located posteriorly and laterally, should be carefully evaluated during MRI reporting, in terms of both its close relationship with anterior cruciate ligament lesions and the clinical symptoms it may cause alone.

Objective: Tinnitus and vertigo are common audiovestibular symptoms in the population. Many diseases can lead to the appearance of these symptoms, but the exact cause can often not be determined. It has been suggested that compression of the cranial nerves by vascular structures may be the cause of various clinical manifestations. This is known as microvascular compression syndrome. Some studies have stated that vascular compression syndromes are a serious pathology, while many studies have argued that vascular compression is only a radiological finding. We aimed to contribute to the literature on vascular compression syndrome and vascular loop types, which is still a controversial topic, and to determine the location of the diameter change in the anterior inferior cerebellar artery in the compression syndrome.Material and Method: Patients who underwent a Magnetic Resonance Imaging (MRI) examination of Temporal Bone due to a complaint of tinnitus or vertigo were retrospectively examined. The complaints of the patients, the diameters of the anterior inferior cerebellar artery (AICA) and the types of vascular loop were evaluated in the high resolution 3D fast imaging employing steady-state acquisition (FIESTA) sequence, according to the CHAVDA classification. The statistical relationship between the age of the patients, anterior inferior cerebellar artery diameters and vascular loop types and their clinical manifestations was investigated.Results: A total of 52 patients were enrolled in the study, of which 28 (53.8%) were male and 24 (46.2%) were female. The mean age of all patients was 47.58±18.734 years. The mean right AICA diameters of the patients were 1.10±0.206 mm, the mean left AICA diameter was 1.11±0.253 mm. Type 1 in 29 patients, type 2 in 12 patients, type 3 vascular loop in 4 patients were observed for the right side, while type 1 in 29 patient, type 2 in 12 patients, and type 3 in 7 patients were observed for the left side. There was no significant difference between vascular loop and tinnitus on the right and left (p=0.705; p=0.335, respectively). There was no significant difference between the right vascular loop and the left vascular loop and the vertigo (p>0.999; p=0.425, respectively). There was no significant difference between the right tinnitus, left tinnitus and vertigo in terms of the diameters of the right and left AICA in the patients (p=0.782; p=0.762; p=0.408; p=0.915, respectively).Conclusion: Vascular compression syndromes are clinical conditions that show symptoms over cranial nerves. Although the vascular loop syndromes originating from AICA have been discussed a lot recently, it is seen that there is no definite opinion. In our study, no association of AICA diameter and vascular loop type with clinical findings was found., Amaç: Tinnitus ve vertigo popülasyonda yaygın görülen audiovestibuler semptomlardandır. Pek çok hastalık bu belirtilerin ortaya çıkmasına yol açabilir. Ancak kesin sebep çoğu zaman belirlenemez. Kranial sinirlerin vasküler yapılar tarafından kompresyonunun çeşitli klinik bulguların sebebi olabileceği öne sürülmüştür. Bu mikrovasküler kompresyon sendromu olarak bilinir. Bazı çalışmalar vasküler kompresyon sendromlarının ciddi bir patoloji olduğunu ifade ederken pek çok çalışmada ise vasküler kompresyonun sadece radyolojik bir bulgu olduğu savunulmaktadır. Halen tartışmalı bir konu olan vasküler kompresyon sendromu ve vasküler loop tipleri hakkında literatüre katkı sağlamayı, anterior inferior serebellar arterdeki (AICA) çap değişikliğinin kompresyon sendromundaki yerini belirlemeyi amaçladık.Gereç ve Yöntem: Tinnitus veya vertigo şikayeti nedeniyle Temporal Kemik Manyetik Rezonans Görüntüleme tetkiki yapılan hastalar retrospektif olarak incelendi. Hastaların şikayetleri, anterior inferior serebellar arter’in çapı ve vasküler loop tipi CHAVDA sınıflandırmasına göre yüksek rezolüsyonlu 3 boyutlu fast imaging employing steady-state acquisition (FIESTA) sekansında değerlendirildi. Hastaların yaşı, anterior inferior serebellar arter çapları ve vasküler loop tipleri ile klinik bulguları arasındaki istatistiksel ilişki araştırıldı.Bulgular: Çalışmaya toplamda 52 hasta alınmış olup bu hastaların 28’i (%53,8) erkek, 24’ü (%46,2) kadındır. Tüm hastaların yaş ortalaması 47,58±18,734 yıldır. Hastaların sağ AICA çaplarının ortalaması 1,10±0,206 mm, sol AICA çap ortalaması 1,11±0,253 mm’dir. Sağ taraf için 29 hastada tip 1, 12 hastada tip 2, 4 hastada tip 3 vasküler loop gözlenirken sol taraf için ise 29 hastada tip 1, 12 hastada tip 2, 7 hastada tip 3 gözlenmiştir. Sağda ve solda vasküler loop ile tinnitus arasında anlamlı bir farklılık bulunmamıştır (sırasıyla p=0,705; p=0,335). Sağ vasküler loop ve sol vasküler loop ile vertigo arasında anlamlı bir farklılık bulunmamıştır (sırasıyla p>0,999; p=0,425). Hastalarda sağ tinnitus, sol tinnitus ve vertigo görülüp görülmemesi arasında sağ ve sol AICA çapları açısından anlamı farklılık bulunmamıştır (sırasıyla p=0,782; p=0,762; p=0,408; p=0,915).Sonuç: Vasküler kompresyon sendromları kranial sinirler üzerinden belirti gösteren klinik durumlardır. AICA kaynaklı vasküler loop sendromları son zamanlarda oldukça tartışılsa da kesin bir kanaat elde edilmediği görülmektedir. Çalışmamızda AICA çapının ve vasküler loop tipinin klinik bulgularla birlikteliği saptanmamıştır.

AIMFungal sinusitis is a disease that was previously considered a rare disease, but has recently been reported with increasing frequency in warm climates. Fungal sinusitis classification has evolved over the past two decades and is said to include five subtypes. Discrimination of different subtypes and knowing their radiological features are important for accurate and rapid diagnosis and initiation of appropriate treatment. In our study, we aimed to investigate whether there is a difference between the radiological findings of AFS with a newly defined finding that may help the diagnosis of AFS; serrated turbinate and those reported in the literature.MATERIALS AND METHODSOur study included 120 patients who underwent paranasal sinus computed tomography examination in our center between January 2019 and September 2021. Patients diagnosed with AFS as a result of allergic tests and/or fungal culture examinations were included in the first group, and patients diagnosed with non-AFS rhinosinusitis were included in the second group. Presence of serrated turbinate appearence, polyps, bone erosion, CT hyperdensity were evaluated in the images.RESULTSThe radiological features of AFS and non-AFS were compaired and serrated turbinate appearence was found to be statistically signifant in AFS (p0.05).CONCLUSIONOur findings showed that serrated turbinate appearence may be a useful radiological marker in the diagnosis of AFS. Bone erosion should be evaluated seperately from other morphological and structural changes in the bone structure, and the bone density measurements should be specified for sinus opacification., AMAÇFungal sinüzit daha önceleri nadir görülen bir hastalık olarak kabul edilen, ancak son zamanlarda sıcak iklimlerde artan sıklıkta bildirilen bir hastalıktır. Fungal sinüzit sınıflandırması son yirmi yılda gelişmiştir ve beş alt tip içerdiği söylenmektedir. Farklı tiplerinin anlaşılması ve bunların radyolojik özelliklerinin bilinmesi doğru ve hızlı tanı ile uygun tedavinin başlatılması açısından önemlidir. Çalışmamızda Alerjik Fungal Sinüzit (AFS) tanısına yardımcı olabilecek yeni bir bulgu olan serrated konka varlığı ile ılıman iklim kuşağında yer alan ülkemizde AFS’nin radyolojik bulgularının literatürde belirtilenler ile farklılığının bulunup bulunmadığını araştırmayı amaçladık.GEREÇ VE YÖNTEMÇalışmamıza Ocak 2019 – Eylül 2021 tarihleri arasında merkezimizde paranazal sinüs BT incelemesi yapılan 120 hasta dahil edilmiştir. Hastalardan alerjik testler ve/veya fungal kültür incelemeleri sonucu AFS tanısı konulanlar birinci grup, AFS dışı rinosinüzit tanısı konulan hastalar ikinci gruba dahil edilmiştir. Görüntülerde serrated konka görünümünün varlığı, polip varlığı, bone erosion varlığı ve CT hiperdansitesi varlığı araştırılmıştır.BULGULARÇalışmamızda AFS’nin radyolojik özellikleri diğer rinosinüzitlerle karşılaştırılmış olup serrated turbinate görünümünün AFS için istatistiksel farklılığını tespit ettik (p0.05).SONUÇOrtaya koyduğumuz bulgular AFS tanısı için serrated konka görünümünün ayırıcı tanıda faydalı bir belirteç olabileceğini göstermiştir. Kemik erozyonun kemik yapıdaki diğer şekil ve yapı değişikliklerinden ayrı değerlendirilmesi, sinüs opasifikasyonu için de dansite değerinin belirtilmesi gerekmektedir.

- Abstract
Introduction: Headache is amongst the most common reasons for consulting a doctor. In addition to impairing the quality of life of the individual, there are societal as well as fiscal outcomes like workforce loss along with health expenditures. MRI findings of patients with headache were examined retrospectively through the relevant literature with a view to scrutinizing the necessity of the very procedure carried out, and the results were shared accordingly. Through our study we delved into the recent situation in our country and investigated whether MRI devices with advancing and novel technologies give dissimilar results with diffusion and susceptibility-weighted images in the MRI findings of patients who seek medical advice visiting a health institution with complaint of headache. Materials and Methods: The study included 224 patients over the age of 18, who underwent brain MRI between January 2020 and December 2021 in our center, with normal findings on neurological examination and who had not undergone surgery. All abnormal appearances such as mass, metastasis, aneurysm, hydrocephalus, encephalitis, sinusitis, mastoiditis, otitis, which may cause secondary headache, were recorded in MR images. Results: Of the 224 patients, 120 (53.57%) were male and 104 (46.43%) were female. The mean age was 39.45±12.55 years. None of the 224 examinations revealed mass suspicious for malignancy, aneurysm, encephalitis, or meningitis. Extraaxial mass lesion compatible with meningioma was detected in 3 patients (1.33%), arachnoid cyst in 3 patients (1.33%), and developmental venous anomaly in 2 patients (0.89%). There was paranasal sinus pathology in 145 patients (64.73%), mastoid pathology in 37 patients (16.52%), and middle ear pathology in 8 patients (3.57%). The remaining 66 patients had no MRI findings except ischemic-gliotic changes, enlarged perivascular distances, and physiological calcifications. Conclusion: In studies designed according to CT and MRI examinations taken regardless of neurological examination and history, the rate of completely normal findings is quite high, as in our study. MRI scans conducted for these patients, who can indeed solely be diagnosed with examination or simpler imaging methods, lead to waste of time and money. In order to fix the said situation, we are of the opinion that the red flag practice should become widespread and nonessential examination requests should be supervised. [ABSTRACT FROM AUTHOR]

Objective: Although inferior turbinate variations are asymptomatic in most cases, symptoms may occur due to inferior turbinate hypertrophy or nasal cavity obstruction. They may even play a role in rhinogenic headache or allergic fungal sinusitis. This study, which has been studied very little and is not found much in the literature, was carried out to investigate and clinically evaluate inferior turbinate variations, Methods: This study was conducted with a total of 376 patients, 176 women (44.8%) and 200 men (50.9%), with a mean age of 36.73 ± 11.62 years, who underwent paranasal sinus computed tomography. Inferior turbinate variations were evaluated in the sections. Results: It was determined that 4.5% (n = 17) of the patients had inferior turbinate variation and 95.5% (n = 359) had no variation. Anatomical variations of inferior turbinate on paranasal sinus computed tomography scan of the 376 patients were examined: serrated 10 (2.5%), bullous 3 (0.8%), paradoxical 1 (0.3%), accessory bifid 2 (0.5%), and hypoplasia 1 (0.3%). Conclusions: In this study, it was determined that inferior turbinate variations were more prevalent than expected, and accessory bifid, serrated, and paradoxical subgroups, which have been reported to be very rare in the literature, were more commonly seen than expected.

Objective: Surgeons performing temporal bone-related procedures must be aware of vascular canal variations. These variations include high-rising jugular bulb, dehiscent jugular bulb, jugular bulb diverticulum and sigmoid sinus bulging. Jugular bulb is where lateral dural venous sinuses meet as they pass through jugular foramen. Two most common abnormalities of jugular bulb are a high-rising jugular bulb and a jugular bulb diverticulum. Etiology of these abnormalities is not fully understood. Jugular bulb diverticulum is an irregular extension of jugular bulb that extends into upper surface of petros part of temporal bone, tympanic cavity, endolymphatic duct, or tvestibular aqueduct. Abnormalities in this area may affect vestibular aqueduct, facial nerve, and posterior semicircular canal, which are located near jugular bulb. Case: 72-year-old woman presented to ENT outpatient clinic with complaints of dizziness that had persisted for one month. Upon examination, right geotropic horizontal nystagmus was detected. MRI of brain revealed bony defect in left pars basilaris of occipital bone, which was continuous with jugular bulb. Patient underwent brain CT angiography and brain CT venography examinations as specialists were still skeptical about mass. Findings supported jugular diverticulum. Clinical symptoms were determined to be unrelated to diverticula, and appearance was deemed incidental. Therefore, surgical intervention was not necessary. Patient's complaints improved after undergoing right apogeotropic gufoni application. Conclusion: We wanted to share this extremely rare variation that may be missed in MRI and CT reporting or confused with other pathologic conditions such as masses. Preoperative knowledge of the variations of vascular structures in temporal bone will guide physicians to prevent serious complications. [ABSTRACT FROM AUTHOR]

Introduction: The authors aim to determine the value of conventional magnetic resonance imaging (MRI) in diagnosis and management of lateral collateral ligament injuries around the ankle joint.Material and Methods: MRI examinations of 50 patients with posttraumatic chronic pain around ankle joint were evaluated retrospectively. There were no oblique coronal sections this series. Ligament rupture and injury were determined according to criteria adopted in the literature. Findings were compared with MRI examinations containing oblique coronal sections of 80 patients made for any reason. All images were retrieved from the archive (PACS).Results: There were lateral collateral ligament (LCL) injuries in 20 cases that had MRI examinations without oblique coronal sections (Series I). All isolated LCL rupture were first degree. Thirty-nine LCL injuries were detected in 80 patients that had MRI examinations containing oblique coronal sections which made for any reason (Series II). Isolated LCL rupture cases were grade one in 63%, grade two in 27% and grade three in 10% in that series. Chi-square test was performed to test for the differences between the two series in determining calcaneofibular ligament rupture. P-value was found 0.011 and was significant at 95% confidence level. Conclusion: Conventional MRI protocols which include oblique coronal sections have critical importance in diagnosis and management of LCL injury., Amaç: Ayak bileği lateral kollateral ligaman patolojilerinin tanısında ve tedavinin yönlendirilmesinde konvansiyonel magnetik rezonans görüntülemenin (MRG) değerini belirlemek.Gereç ve Yöntem: Ayak bileğinde travma sonrası gelişen kronik ağrı şikayetiyle oblik koronal kesitler alınmaksızın MRG incelemesi yapılan 50 olgu arşiv sisteminden (PACS) retrospektif olarak değerlendirildi. Ligamanlardaki rüptür ve zedelenme kabul edilen kriterlere göre saptandı. Bulgular herhangi bir sebeple ayak bileği MRG yapılmış ve oblik koronal kesitler alınarak incelenmiş retrospektif değerlendirilen 80 olguluk diğer bir seri ile kıyaslandı.Bulgular: Oblik koronal kesitler alınmaksızın inceleme yapılan birinci seride; 20 olguda lateral kollateral ligaman kompleksi (LKLK) yaralanmaları mevcuttu. Bu serideki izole LKLK rüptürlerinde sadece birinci derece rüptür saptanabildi. Oblik koronal kesitler alınarak incelenen ve herhangi bir sebeple ayak bileği MR tetkiki yapılan 80 hastada (seri 2) toplam 39 LKLK rüptürü tespit edildi. Bu serideki izole LKLK rüptürlerinde; birinci derece rüptürlerin sıklığı %63, ikinci derece rüptürlerin sıklığı %27, üçüncü derece rüptürlerin sıklığı %10 olarak tespit edildi. Kalkaneofibular ligaman rüptürünün tespitinde iki seri arasındaki farklılığı test etmek amaçlı yapılan ki-kare testinde p değeri 0,011 bulundu. %95 güven düzeyinde bu iki değişken arasındaki ilişki istatistiksel olarak anlamlı görüldü.Sonuç: Oblik koronal kesitlerin alındığı Konvansiyonel MRG protokolleri lateral kollateral ligaman kompleksi rüptürlerinin tanısında ve tedavinin yönlendirilmesinde kritik öneme sahiptir.

ÖZET MEDIAL ORBITAL PROTRÜZYONUN CANALIS ETHMOIDALS ANTERIOR İLE İLİŞKİSİ VE KLİNİK ÖNEMİ: RADYOANATOMİK ÇALIŞMA Arteria ethmoidalis anterior, canalis ethmoidalis anterior içerisinde seyreden, konvansiyonel ve fonksiyonel endoskopik sinüs cerrahisi sırasında hem lokalizasyonu belirleyen bir referans noktası olarak, hem de işlem sırasında olası hasarında orbital ve intrakranial önemli komplikasyonlara yol açması veya bu işlemler esnasında ciddi epistaksisin sebebi olması bakımından önemli bir yapıdır. Orbita içerisinde arteria ophtalmica'dan ayrılan bir dal olan arteria ethmoidalis anterior; foramen ethmoidale anterius yolu ile etmoid sinüs içerisine geçerek canalis ethmoidalis anterior vasıtası ile etmoid çatıya ulaşır. Bilgisayarlı tomografi son yıllarda özellikle koronal planda konvansiyonel radiografiye sağladığı önemli üstünlükle sinüs ve orbita hastalıkları ile operasyonu ilgilendiren varyasyonlar ile ilgili tanının önemli bir parçasını oluşturmuştur. Orbita medial duvarı anteriorunda bulunan foramen ethmoidale anterius'un lokalizasyonu ve canalis ethmoidalis anterior'un seyri çeşitli varyasyonlar gösterir. Orbita medial duvarında bir diğer anomali de duvarın çeşitli noktalarda etmoid sinüs içerisine bulging ve protrüzyon göstererek orbital içeriğin etmoid sinüs içerisine uzanmasıdır. Bu iki yapının ilişkisi literatürde daha önce incelenmemiştir. Çeşitli paranazal sinüs şikayetleri ile BT istenen 600 hastaya aksial ve koronal düzlemde 1 mm kesit kalınlığında incelemeler yapılmış, orbita medial duvarı koronal düzlemde superior ve inferior olarak, transvers düzlemde dört eşit kadrana ayrılarak protrüzyonların ve canalis ethmoidalis anterior'un lokalizasyonları araştırılmıştır. Canalis ethmoidalis anterior'un 37özellikle ikinci %'lük ve daha sonra üçüncü %'lük kadranda yerleştiği tespit edilmiş, protrüzyon lokalizasyonu ile canalis ethmoidalis anterior'un bulunduğu kadran arasında istatistiksel ilişki saptanmıştır. Kemik yapıdaki zayıf bir noktadan gerçekleşmesini beklediğimiz orbital protrüzyonun özellikle canalis ethmoidalis anterior'u ilgilendiren lokalizasyonunun bilinmesinin, sinüs cerrahisi sırasında gerçekleşebilecek komplikasyonların önlenmesi açısından önemli olduğu düşünülmüştür. BT bu ilişkiyi ortaya koymada tam ve yeterli tanı aracıdır.

Its injury during these interventions may lead to important orbital and intracranial complications and also severe epistaxis. anterior ethmoidal artery, which is an intraorbital branch of the ophtalmic artery; passes through the ethmoidal sinus by anterior ethmoidal foramen and reaches the ethmoid roof through via the anterior ethmoidal canal. The computed tomography particularly by supplying opportunity to coronal sections of the conventional radiography has currently become an important part of the diagnosis for the variations related with the surgical operations directed to paranasal sinuses and the orbital pathologies. The course of the anterior ethmoidal foramen and anterior ethmoidal canal which are located at the medial wall of the orbita shows several variations. Another anomaly located at the medial wall of the orbita is the protrusion and bulging of the orbital content into the ethmoidal sinus at different points of the wall. The relationship between these two structure has not been studied previously. CT images of 600 patients with various symptoms related with paranasal sinuses were analyzed to visualize the localization of the anterior ethmoidal canals and to determine the presence of orbital protrusions. The 1 mm thick sections were obtained in the axial and coronal planes and the 39medial wall of the orbita has been evaluated in 4 equisections divided by imaginary lines passing superiorly and interiorly in coronal plane and another line in the transverse plane. It has been found that the anterior ethmoidal canal was especially located in the second quadrisection and secondarily in the third quadrisection. A statistical correlation was found between the localization of the protrusion and the qudrisection that contains the anterior ethmoidal canal. It was expected that the orbital protrusion occurs from a weak point in the bony structure. For the reason, knowing the localization of the anterior ethmoidal canal is thought to be important for preventing the complications regarding the sinus surgery. CT is a precise and sufficient diagnostic tool for putting forward this relation. Key Words: Anterior ethmoidal canal, Computed Tomography (CT), ethmoid sinus, orbital protrusion, radioanatomy 40 47

Objective: Headache is amongst the most common reasons of consulting a doctor. In addition to impairing the quality of life of the individual, there are societal as well as fiscal outcomes like workforce loss along with health expenditures. MRI findings of patients with headache were examined retrospectively through the relevant literature with a view to scrutinizing the necessity of the very procedure carried out, and the results were shared accordingly. Through our study we delved into the recent situation in our country and investigated whether MRI devices with advancing and novel technologies give dissimilar results with diffusion and sensitivity-weighted images in the MRI findings of patients who seek medical advice visiting a health institution with complaint of headache. Methods: The study included 224 patients over the age of 18, who underwent brain MRI between January 2020 and December 2021 in our center, with normal findings on neurological examination and who had not undergone surgery. All abnormal appearances such as mass, metastasis, aneurysm, hydrocephalus, encephalitis, sinusitis, mastoiditis, otitis, which may cause secondary headache, were recorded in MR images. Results: Of the 224 patients, 120 (53.57%) were male and 104 (46.43%) were female. The mean age was 39.45±12.55 years. None of the 224 examinations revealed mass suspicious for malignancy, aneurysm, encephalitis, or meningitis. Extraaxial mass lesion compatible with meningioma was detected in 3 patients (1.33%), arachnoid cyst in 3 patients (1.33%), and developmental venous anomaly in 2 patients (0.89%). There was paranasal sinus infection in 145 patients (64.73%), mastoiditis in 37 patients (16.52%), and otitis in 8 patients (3.57%). The remaining 66 patients had no MRI findings except ischemic-gliotic changes, enlarged perivascular distances, and physiological calcifications. Conclusion: In studies designed according to CT and MRI examinations taken regardless of neurological examination and history, the rate of completely normal findings is quite high, as in our study. MRI scans conducted for these patients, who can indeed solely be diagnosed with examination or simpler imaging methods, lead to loss of time and money. In order to fix the said situation, we are of the opinion that the red flag practice should become widespread and nonessential examination requests should be supervised. [ABSTRACT FROM AUTHOR]

Objective: The plantaris muscle is a short, thin, spindleshaped muscle with a long tendon. The course and endpoint of the plantar tendon is an important factor in Achilles middle segment tendinopathies. The plantar tendon can also be used as a graft in many parts of the body. Variations of the plantaris muscle and tendon are common. It is thought that its contribution to Achilles tendinopathy may be related to these variations. Ultrasonography and MRI are radiological methods in which the plantaris tendon can be evaluated. We aimed to evaluate this structure, which has limited studies in the literature, in routine ankle MRI examinations in detail and to contribute to the literature. Methods: Presence of the plantar tendon in 155 ankle MR images of 139 patients, its diameter, its course separately or together with the Achilles tendon, the localization of the calcaneal attachment of the tendon, the distances between the plantar tendon and the endpoints of the Achilles tendon, the junction of the plantar tendons connecting with the Achilles tendon The distance of the achilles tendon to the calcaneal end level of the Achilles tendon was evaluated. Results: A total of 155 individuals, 105 (67.74%) female and 50 (32.26%) male, were included in the study. The plantar tendon was visualized in 142 (91,61%) of 155 cases. In 115 (74.2%) of 142 cases in which the plantar tendon was imaged, the plantar tendon was inserted into the calcaneus separately from the Achilles tendon and was joining the Achilles tendon at various levels in 27 cases (17.41%). The mean diameter of the tendon was found to be 2.77±0.90 in all cases. In 27 cases where the plantar tendon joined with the Achilles tendon, the distance from the junction point to the calcaneal insertion was 15±9.90 cm. Conclusion: The results we obtained in our study are compatible with the radiological and cadaveric research results in the literature. In our study, the tendon thickness was higher in men than in women, and the diameter of the tendons ending in the calcaneus was among the tendons merging with the Achilles tendon; We also revealed that the diameter of the medial terminating ones is greater than the anterior terminating ones. In conclusion, we think that the importance of the plantar tendon should be well understood by clinicians, especially radiologists and orthopedists, and this tendon should not be ignored in MRI reports.

- Abstract
Background/aim: The aims of this study are to determine the incidence and more frequent localizations of orbital fat tissue herniation accompanying dehiscences in the medial orbital wall and to investigate the relationship between orbital fat tissue herniations and the anterior and posterior ethmoidal foramina., Material and Methods: One thousand two hundred patients who had undergone computed tomography with a preliminary diagnosis of sinusitis and who had no previous facial, orbital, paranasal sinus surgeries or history of trauma were retrospectively analyzed. The localization of the ethmoidal foramina and orbital fat tissue herniations were marked. In patients with orbital fat tissue herniation, the relationship between the localization of orbital fat tissue herniation and the anterior and posterior ethmoidal foramina was investigated., Results: The incidence of orbital adipose tissue herniation in our study was 7.9%. Of the 98 herniations on the bilateral medial orbital wall, 60 were in zone 3, and the most common herniation site was zone 3. A statistically significant difference was noted between the localization zone of the anterior ethmoidal foramen and the localization zones of orbital fat tissue herniations (Fisher's exact test, p < 0.001)., Conclusion: Zone 3 is the weakest area of the medial orbital wall, and zone 3 is the most prone to herniation of fat tissue. The association of orbital fat tissue herniations with the anterior ethmoidal foramen is extremely common. Being cognizant of this finding may help a surgeon better estimate the anatomical view to be met before functional endoscopic sinus surgery as well as to minimize the risk of possible orbital complications, especially anterior ethmoidal artery injury., (© TÜBİTAK.)
