Background. Fulminant myocarditis (FM) is a potentially lethal condition in children due to rapid progressive hemodynamic instability and cardiogenic shock. Patients with FM might show different clinical manifestations on emergency department admission. Case. Herein, we describe the case of a 12-year-old girl who was admitted to our institution’s emergency department due to complaints of abdominal pain and incessant vomiting. However, we detected an early onset of atrial fibrillation (AF) accompanied by FM. The patient’s condition of AF and severe hemodynamic disorder was successfully treated in our institution’s pediatric intensive care unit. Conclusion. To the best of our knowledge, this is the first report of the co-occurrence of FM and AF successfully treated in childhood. This case report will serve as a guide for the treatment of cases with FM accompanied by AF.

Cor triatriatum sinister is a rare congenital cardiac anomaly. The anomaly is caused by a fibromuscular membrane that divides the left atrium into two cavities. This membrane can lead to the obstruction of left atrial flow and also create pulmonary venous hypertension. Pulmonary arteriovenous malformation (PAVM) is notorious for its aberrant blood flow between the pulmonary arteries and veins. Herein, we report a case of a 4-year-old toddler who had a unique form of pulmonary hypertension presenting with cor triatriatum sinister and diffuse PAVM. After the surgical treatment of cor triatriatum sinister, both pulmonary arteriovenous malformation and pulmonary hypertension disappeared.

Aim: To investigate the relationship of cartilage loss in tibiofemoral and patellofemoral joints with the number, size and location of loose bodies in secondary synovial chondromatosis (SC). Methods: Eighty-eight patients with secondary SC were evaluated retrospectively. The size and location of loose bodies were evaluated by both X-ray and magnetic resonance imaging. The relationship between cartilage lesions and the number, location and size of loose bodies were assessed by Chi-square test and Fisher’s exact test. Results: When the relationship between the presence of loose body and cartilage damage was evaluated, it was observed that 83% of subjects (n=74) had cartilage loss at the tibiofemoral joint, 75% (n=66) on the medial and 9% (n=8) of patients had on the lateral side. It was determined that when the number of loose bodies was ≤5, the mean diameter was 7.3 mm (2-21 mm). It was 12.7 mm (2-30 mm) when the number was >5. The most frequently affected locations were the posterior compartment of the posterior cruciate ligament and the superior compartment of the popliteal fossa, regardless of the degree of cartilage loss. Conclusion: We concluded that the higher the cartilage damage, the higher the number and size of loose bodies. We assume that our study provides insight into further investigations to study new classification system for secondary SC in the knee joint.

Focal nodular hyperplasia (FNH) and hemangioma are benign and generally asymptomatic hepatic tumors. With distinctive imaging findings on dynamic computed tomography (CT) and magnetic resonance imaging (MRI), differentiation of these benign hepatic tumors from metastases can be made. We described imaging findings of these hepatic lesions in a 57-year-old man who presented with rectal adenocarcinoma for staging.

PURPOSEThe aim of this study was to evaluate the prognostic quality of adjacent vessel sign (AVS) in malignant breast tumors by comparing it with classical prognostic pathological biomarkers and magnetic resonance imaging (MRI) findings.METHODSA total of 124 patients with 133 malignant lesions were included. All the imaging was performed on a 1.5T Avanto scanner and the images were interpreted according to BI-RADS-MR® (fifth ed.) atlas. Maximum intensity projection (MIP) images were constructed from subtracted post-contrast images and were used to investigate AVS. Histopathological results and MRI findings were compared with AVS.RESULTSInterobserver agreement about AVS status was substantial (κ=0.64). AVS positive lesions were significantly bigger in size (P < .001, AVS negative: median 12 mm, AVS positive: median 31 mm). AVS was significantly associated with increased Ki-67 index and axillary lymph node metastasis (P=.009 and P=.019, respectively). Between AVS and lymphovascular invasion (LVI), there was a trend toward positive relationship (P=.076). MRI findings of T2 hypointensity, peritumoral edema, irregular shape, non-homogeneous contrast enhancement, rapid early contrast enhancement, and skin infiltration showed significant positive relation with AVS (P < .001, P < .001, P < .001, P=.02, P=.021, and P=.021, respectively). AVS is found to be associated with increased Ki-67 index, axillary lymph node metastasis, and some MRI findings that point to malignancy or poor prognosis.CONCLUSIONAVS indicates poor prognosis since it is related to axillary lymph node metastasis, increased Ki-67 index, LVI, peritumoral edema, rapid early contrast enhancement, increased background enhancement, skin extension, T2 hypointensity, non-homogeneous contrast enhancement, irregular lesion shape, and larger tumor size. AVS is an easy to use sign that shows substantial interobserver agreement.

To the Editor, Apert syndrome is a genetic disorder characterized by several clinical manifestations including craniosynostosis, midface hypoplasia, and symmetric syndactyly of both hands and feet. Type B is located between the left carotid artery and left subclavian arteries, while type C is located between the left carotid artery and innominate arteries.[6] In this current case report, the patient was diagnosed with IAA type B. Cohen and his colleagues have conducted the most extensive clinical study about patients with Apert syndrome who also had congenital heart diseases. Cohen et al. investigated 136 patients with Apert arch syndrome and reported a 10% incidence rate of cardiac anomaly. [Extracted from the article]

Background: Early detection of coronary artery disease (CAD) is important because of the high morbidity and mortality rates. As invasive coronary angiography (ICA) is an invasive procedure, an alternative diagnostic method; coronary computed tomography angiography (CTA), has become more widely used by the improvements in detector technology. Aims: In this study, we aimed to examine the accuracy and image quality of high-pitch 128-slice dual-source CTA taking the ICA as reference technique. We also aimed to compare the accuracy and image quality between different heart rate groups of >70 beates per minute (bpm) and ≤70 bpm. Study Design: Retrospective cross-sectional study. Methods: Among 450 patients who underwent coronary CTA with the FLASH spiral technique, performed with a second generation dual-source computed tomography device with a pitch value of 3.2, 102 patients without stent and/or bypass surgery history and clinically suspected coronary artery disease who underwent ICA within 15 days were enrolled. Image quality was assessed by two independent radiologists using a 4-point scale (1=absence of any artifacts- 4=non-evaluable). A stenosis >50% was considered significant on a per-segment, per-vessel, and per-patient basis and ICA was considered the reference method. Radiation doses were determined using dose length product (DLP) values detected by the computed tomography (CT) device. In addition, patients were classified into two groups according to their heart rates as ≤70 bpm (73 patients) and >70 bpm (29 patients). The relation between the diagnostic accuracy and heart rate groups were evaluated. Results: Overall, 1495 (98%) coronary segments were diagnostic in 102 patients (32 male, 70 female, mean heart rate: 65 bpm). There was a significant correlation between image quality and mean heart rate in the right coronary artery (RCA) segments. The effective radiation dose was 0.98±0.09 mili Sievert (mSv). On a per-patient basis, sensitivity, specificity, and positive and negative predictive values were 93.8%, 88.8%, 93.8% and 88.8%, respectively. These values were also similar in per-vessel and per-segment basis. Two different groups categorized by mean heart rate had almost similar results in terms of the diagnostic power of dual-source CTA. Conclusion: CTA with a high pitch value is a reliable, non-invasive diagnostic method that can CAD with low radiation doses not only in patients with a heart rate below 70 bpm, but also in patients with higher heart rates.
