A 35-year-old businessman with a history of migraine with aura developed new neck pain while lying on a sofa in his home. He was given neck massage and physical therapy for a day, and subsequently after two days developed severe generalized headache when sitting or standing. He was hospitalized in his hometown. Investigations revealed venous sinus thrombosis and bilateral thin subdural collections for which he was anticoagulated. Headache improved and then worsened and became severe in all positions. He was then admitted under our care. MRI scan of the brain at our hospital showed left subdural hematoma with midline shift. It required urgent evacuation. His previous first brain MRI was re-evaluated. It showed characteristic features of spontaneous intracranial hypotension (SIH). If not recognized early, SIH results in various complications, some of which require immediate intervention. Any change in the pattern of headache in SIH one must alert the clinician due to the possibility of one of its complications.

The article discusses the highlights of the 35th annual meeting of the International Society for Pediatric Neurosurgery (ISPN) held at the Saint Georges Hall in Liverpool, England from September 9 to 13, 2007. Doctor Rick Abbott from the U.S. replaced Doctor Carlo Mazza as president of the organization. It outlines several papers presented by a group of Indian physicians related to pediatric neuroscience. A 3-cycle ISPN course has been provided to Indian participants for 2009, along with Kolkata IndSPN meeting.

Cerebrospinal fluid (CSF) rhinorrhoea is a well known complication following skull base surgery. Identifying the site of leak is the most important determinant for the appropriate approach in the further management of the case. Either transcranial or transnasal approaches may be used, alone or in combination, as deemed appropriate. The success of the repair depends on the site of the fistula, the timing of surgery, and patient factors. Discussion of two illustrative cases is presented here to describe the challenges faced by the neurosurgeon in the recognition and the immediate and definitive management of postoperative CSF rhinorrhoea and various strategies for a successful outcome in their repair., (© 2025.

Intraoperative bleeding poses a substantial challenge, particularly in neuro-spine surgeries leading to complications such as hematomas, infections, and hemodynamic instability. Despite their proven efficacy, use of topical hemostatic agents (THAs) lacks comprehensive published literature and guidelines particularly in the Indian setting. The present study provides the first-ever Indian expert panel recommendations for effective adjunct THA use in different intraoperative bleeding sites and situations in neuro-spine surgeries. A comprehensive approach, encompassing a literature review, followed by experience sharing in a meeting using a survey helped integrate expert opinions in the form of practical algorithms to guide THA selection. Our survey results revealed a strong inclination towards specific THAs, flowable gelatin + thrombin being choice of THA for difficult to access and problematic bleeding situations during tumor removal/resection, transsphenoidal hypophysectomy and skull-based procedures. Both oxidized regenerated cellulose (ORC)/Fibrillar and flowable gelatin + thrombin were recommended for continuous oozing. ORC/Fibrillar was preferred for arteriovenous and cavernous malformations. This expert-panel guidance on THA use aims to optimize hemostat use practices and improve surgical outcomes in neuro-spine surgery., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Management of lateral and third ventricular tumors has been a challenge for neurosurgeons. Advances in imaging and pathology have helped in a better understanding of the treatment options. Technical refinement of microsurgical technique and addition of endoscopy has enabled more radical excision of tumors, when indicated, and added more safety.A proper understanding of the pathology at various ages and treatment options is continuously evolving. Many pediatric tumors are amenable to conservative surgical methods with effective complementary treatments. However, radical surgery is required in many adults as the main treatment and for many benign tumors. Various intraventricular lesions encountered and their surgical management is reviewed here for their efficacy, safety, and outcome, encompassing changes in our practice over the last 20 years., (© 2024.

During the last 30 years, the neurosurgeons have witnessed a revolution in the practice of interventricular surgery. The advent of neuroendoscopy at the end of the 1980s has allowed a minimally invasive management of a very large series of pathologies in pediatric neurosurgery ranging from hydrocephalus to arachnoid cyst to intraventricular tumors. The progresses in the management of hydrocephalus, intracranial cyst, and the fluid filled collection nevertheless has been more rapid and radical due to the simpler equipment that is necessary to perform this kind of surgery. The intraventricular tumors instead have been addressed in a slower way, and for many years, the only endoscopic procedure that was allowed on interventricular tumors was a biopsy associated with the management of hydrocephalus. Only very small tumors have been considered operable for complete removal during many years due to the limitations of the neuroendoscopic equipment and to the small calibers of the working channel. More recently, the advent of new devices and new surgical techniques are offering new perspectives on the possibility of intraventricular tumor surgery in children. In this review, we describe the historical perspective of the learning curve of intraventricular tumor surgery under neuroendoscopic control and try to offer a view of the future perspective in the removal of larger intraventricular tumors, analyzing the main indications for intraventricular endoscopic tumor surgery. We offer as well an historical perspective of the evolution of skull base surgery and endonasal transsphenoidal approach for skull-based tumors in children. This kind of surgery that has acquired widespread acceptance for many pathologies in adult age has diffused more slowly in pediatric neurosurgery due to the anatomical limitation observed in these age range. Also in this field, the slow evolution of the technique and of the technology available to neurosurgeons has allowed a very significant expansion of indication for the minimally invasive removal of skull base tumors in children., (© 2023.

Introduction: Pineal region tumours (PRTs) are more common in children and represent a wide variety of lesions. The practise of a radiation test dose is obsolete and a biochemical/histological diagnosis is recommended before further therapy. Many patients present with hydrocephalus. Advances in neuroendoscopic techniques have allowed safe and effective management of this obstructive hydrocephalus with an opportunity to sample cerebrospinal fluid (CSF) and obtain tissue for histopathology. Definitive surgery is required in less than a third. Endoscopic visualisation and assistance is increasingly used for radical resection, where indicated., Methodology: Our experience of endoscopic surgery for paediatric PRTs from 2002 to 2021 is presented. All patients underwent MRI with contrast. Serum tumour markers were checked. If negative, endoscopic biopsy and endoscopic third ventriculostomy (ETV) were performed; and CSF collected for tumour markers and abnormal cells. For radical surgery, endoscope-assisted microsurgery procedures were performed to minimise retraction, visualise the extent of resection and confirm haemostasis., Results: M:F ratio was 2:1. The median age of presentation was 11 years. Raised ICP (88.88%) was the commonest mode of presentation. Nineteen patients had pineal tumours, one had a suprasellar and pineal tumour, one had disseminated disease, while six had tectal tumours. The ETB diagnosis rate was 95.45%, accuracy rate was 83.3% and ETV success rate was 86.96%., Conclusion: Neuroendoscopy has revolutionised the management of paediatric PRTs. It is a safe and effective procedure with good diagnostic yield and allows successful concurrent CSF diversion, thereby avoiding major surgeries and shunt implantation. It is also helpful in radical resection of lesions, where indicated., (© 2022. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Introduction  Cerebral cavernous malformations (CCMs) account for about 5 to 13% of intracranial vascular malformations. Cystic cerebral cavernous malformations (cCCMs) are a rare morphological variant and can cause diagnostic and therapeutic dilemmas. We describe our five such cases and review the existing literature on this entity. Methods  A search of the PubMed database for cCCMs was done, and all articles in English emphasizing the reporting of cCCMs were selected. A total of 42 publications describing 52 cases of cCCMs were selected for analysis. Epidemiological data, clinical presentation, imaging features, the extent of resection, and outcome were analyzed. Radiation-induced cCCMs were excluded. We have also described five of our cases of cCCMs and reported our experience. Results  The median age at presentation was 29.5 years. Twenty-nine patients had supratentorial lesions, 21 had infratentorial lesions, and 2 had lesions in both compartments. Among our four patients, three had infratentorial lesions, whereas one had a supratentorial lesion. Multiple lesions were seen in four patients. A majority (39) had symptoms of mass effect (75%), and 34 (65.38%) had raised intracranial pressure (ICP), whereas only 11 (21.15%) had seizures. Among our four operated patients, all of them had symptoms of mass effect, and two of them also had features of raised ICP. The extent of resection was gross total in 36 (69.23%), subtotal in 2 (3.85%), and not reported in 14 (26.93%). All four of our operated patients underwent gross total resection, but two of them underwent a second surgery. Of the 48 patients in whom the surgical outcome was reported, 38 improved (73.08%). One showed a transient worsening followed by improvement, one developed a worsening of the pre-existing focal neurological deficit (FND), two developed a new FND, and 5 had no improvement in their FNDs. Death occurred in one patient. All four of our operated patients improved after surgery, although three of them showed a transient worsening of FNDs. One patient is under observation. Conclusion  cCCMs are rare morphological variants and can cause considerable diagnostic and therapeutic dilemmas. They should be considered in the differential diagnosis of any atypical cystic intracranial mass lesion. Complete excision is curative, and the outcome is generally favorable; although transient deficits may be seen., Competing Interests: Conflict of Interest None declared., (Asian Congress of Neurological Surgeons.

Objective: Giant (maximum diameter ≥ 4 cm) pituitary macroadenomas are complex tumors that require resection for decompression of optic nerves, relief of mass effect, and symptom improvement. Given the lack of surgical accessibility, the lateral extent of the lesions, and the invasion of the cavernous sinus, management presents a significant challenge. Transsphenoidal, transcranial, and combined approaches have been viable options for resection. The authors present their findings from a large series of patients to characterize giant pituitary adenomas, document outcomes, and outline surgical nuances in resection of these tumors., Methods: The authors reviewed 887 consecutive patients who underwent resection of pituitary adenomas at a single institution. From this group, 108 patients with giant pituitary adenomas who underwent resection between January 1, 2002, and December 31, 2020, were identified for inclusion in the study. The patient demographics, clinical presentation, tumor imaging characteristics, surgical approaches, and postoperative outcomes were analyzed using descriptive statistics., Results: The mean preoperative tumor diameter in this cohort was 4.6 ± 0.8 cm, with a mean volume of 25.9 ± 19.2 cm3. Ninety-seven patients underwent transsphenoidal approaches only, 3 underwent transcranial resection, and 8 patients underwent a combined approach. Gross-total resection was achieved in 42 patients. Tumor stability without a need for additional therapy was achieved in 77 patients, with 26 patients undergoing subsequent adjuvant radiotherapy. Among 100 patients with sufficient follow-up, 14 underwent adjuvant therapy-repeat operation and/or adjuvant radiation therapy-because of recurrence or tumor progression. Six patients with recurrence were observed without additional treatment. Overall, the morbidity associated with removal of these lesions was 11.1%; the most common morbidities were cerebrospinal fluid leak (5 patients, 4.6%) and hydrocephalus (4 patients, 3.7%). One death due to postoperative pituitary apoplexy of the residual tumor and malignant cerebral edema occurred in this cohort., Conclusions: Giant pituitary tumors still represent a surgical challenge, with significant morbidity. Gross-total resection occurs in a minority of patients. Surgical goals for removal of giant pituitary tumors should include attempts at removal of most tumor tissue to minimize the risk of residual tumor apoplexy by tailoring the approach along the major axis of the tumor. Experience with both transsphenoidal and multiple transcranial techniques is necessary for minimizing complications and improving outcomes.

Introduction: Cavernous angiomas of the brain (CCM) are being increasingly diagnosed, especially in the paediatric age group. Though classic presentations with haemorrhage or seizures are well recognised, presentation as a large lesion with mass effect is rare and creates difficulty in diagnosis as well as management., Methods: Our cases of paediatric giant CCMs that presented as a 'mass lesion' are reported here, and the PubMed database for giant CCMs in the paediatric population is reviewed. All articles where the size of the lesion was reported to be > 4 cm were selected for analysis to study the varying modes of presentation, treatment, and outcome; to gain a proper perspective on this distinct entity of 'giant CCMs'., Results: Analysis of a total of 53 cases (inclusive of our 3 cases) reported so far showed slight male preponderance (58.49%). The largest reported lesion was 14 cm in largest diameter. Most of the lesions (83.02%) occurred in the supratentorial region. In the infratentorial region, paediatric giant CCMs were more commonly seen in the cerebellum than in the brainstem. Seizures were observed in 47.17% at presentation. Features of mass effect were the mode of presentation in all our cases, and literature analysis has shown raised intracranial pressure in 37.74% (20 patients) and focal neurological deficit in 33.96% (18 patients) at presentation. Macrocephaly was seen in younger children up to the age of 7 years (16.98% or 9 patients). Gross total resection was carried out (with a good outcome) in all our cases and in 36 of the other 49 analysed patients who were operated on., Discussion: About one-fourth of CCMs occur in paediatric patients. Giant CCMs are rare but can present in children even in the immediate post-natal period. Features of a mass lesion such as raised intracranial pressure, macrocephaly, and focal neurological deficit are much more common than their smaller counterparts. Their appearance on imaging also often causes diagnostic dilemmas with other intracranial mass lesions. Timely surgery with standard microsurgical principles leads to a favourable outcome in the majority., Conclusion: Giant CCMs, though rare, often present as a diagnostic challenge. Presentation with mass effect is common, and complete microsurgical excision remains the mainstay of treatment. Though transient neurological deficits may be encountered with this strategy, the long-term outcome remains favourable., (© 2021.

Introduction: Craniopharyngiomas constitute 2-4% of intracranial neoplasms. Intraventricular craniopharyngiomas (IVCrs) are the rarely encountered varieties of these lesions. Objective: The objective of the study was to study the special features in clinical presentation, imaging, management, and surgical outcome of IVCrs. Materials and Methods: This retrospective analysis included the combined experience from two tertiary care institutions. Medical records of histopathologically proven cases of IVCrs from January 1994 to June 2021 were assessed, and images were analyzed based on the criteria by Migliore et al. for inclusion of solely intraventricular lesion with the third ventricular ependyma demarcating it from the suprasellar cistern. Results: Among the 25 patients included (mean age: 35.4 years), the most common presentation included headache ( n = 21, 84%), vomiting and other features of raised ICP ( n = 18, 72%), visual complaints ( n = 12, 48%), and endocrinopathies ( n = 11, 44%). Fifteen had predominantly cystic tumors, two were purely solid, and eight were of mixed consistency. Primary open microsurgical procedures were performed in 18 (72%) patients, of which four (16%) were endoscope-assisted. Seven (28%) underwent a purely endoscopic procedure. One underwent a staged surgery with endoscopic cyst fenestration and intracystic interferon (IFN)-alpha therapy, followed by microsurgical excision. Complete excision was achieved in 10 patients, near-total in nine, and partial excision in six. Four patients underwent a ventriculoperitoneal shunt (one before the definitive procedure). At a median follow-up of 36 months (range:11-147 months), five patients developed a recurrence, and one had a stable small residue. This patient and two others with small cystic recurrences were observed. One patient was managed with radiotherapy alone. Another underwent re-surgery after a trial of radiotherapy, and the last patient developed a local recurrence, which was managed with radiotherapy; he then later developed an intraparenchymal recurrence, which was operated. Conclusion: Purely IVCrs present with raised intracranial pressure, and visual disturbances are less common. Their deep-seated location and limited surgical field-of-view makes minimally invasive endoscopic-assisted surgery most suitable for their excision. The thin-walled cystic lesions may be occasionally adherent to the ependymal wall in close vicinity to the thalamus-hypothalamus complex, making complete excision difficult. Their responsiveness to radiotherapy, often leads to a gratifying long-term outcome., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Deopujari, Behari, Shroff, Kumar, Thombre, Karmarkar and Mohanty.)

Hydrocephalus is a common clinical problem encountered in neurosurgical practice. With greater subspecialisation, pediatric neurosurgery has emerged as a special discipline in several countries. However, in the developing world, which inhabits a large pediatric population, a limited number of neurosurgeons manage all types of hydrocephalus across all ages. There are some essential differences in pediatric and adult hydrocephalus. The spectrum of hydrocephalus of dysgenetic origin in a neonate and that of normal pressure hydrocephalus of the old age has a completely different strategy of management. Endoscopic third ventriculostomy outcomes are known to be closely associated with age at presentation and surgery. Efficacy of alternative pathways of CSF absorption also differs according to age. Managing this disease in various age groups is challenging because of these differences in etiopathology, tempo of the disease, modalities of investigations and various treatment protocols as well as prognosis., Competing Interests: None

Introduction: Benign lesions of the skull base are common in the paediatric population, and are usually congenital in aetiology. Majority of these lesions are treated transcranially exposing the patients to a number of risks. Although endoscopic endonasal surgery (EES) helps avoid many of these potential morbidities, CSF leak with its attendant complication remains a big concern. This study reports the use of the Hadad flap in the reconstruction of skull base defects in infants to prevent this problem. The study was conducted on four infants with a mean age of 7 months, who underwent repairs for CSF leaks associated with congenital lesions like meningocele or meningoencephalocele, using the Hadad flap. Of the four patients, three cases were revision cases and one was primary where the patients presented with complaints such as nasal obstruction and watery nasal discharge. Post surgery, the infants were monitored for a mean period of 23 months and no major complications or recurrent CSF drainage were observed. Minor complications that were observed include vestibulitis and crusting in the nose. The utility of the Hadad flap in the reconstruction of skull base defects in the paediatric age group has been controversial while its utility in infants has not been studied in literature so far. We report here in our series four infant patients in whom we believe that the nasal septum and the skull base will develop proportionally to each other, hence lowering the chances of a short flap and eliminating the occurrence of future complications., Conclusion: The nasoseptal flap is an effective and safe technique for reconstructing skull base defects in infancy. It can be concluded that this technique does not have any potential effect on septal or craniofacial growth as the flap is harvested only on one side with normal mucosal cover on the other side. There is no posterior septectomy or any form of bony or cartilaginous resection that is performed, hence avoiding any effects on bony growth. No studies have been published in literature so far and to the best of our knowledge, this is the first report describing the efficacy of the nasoseptal flap in infants.

Background: Subdural empyema denotes the collection of purulent material in the subdural spaceand is commonly seen in infants and older children. In infants, the most common cause is bacterialmeningitis. In older children, sinusitis and otitis media are usually the source for subdural empyema. Theclinical symptomatology is varied and has a wide range including prolonged or recurrent fever, seizures,meningeal irritation, and raised intracranial pressure. It can mimic as well as complicate meningitis and aheightened clinical awareness is therefore paramount., Aims and Objectives: The clinical profile, etiopathogenesis, imaging features and management of subdural empyema in children is discussed and the relevant literature is reviewed., Conclusion: Subdural empyema is a neurosurgical emergency and rapid recognition and treatment canavoid life-threatening complications. In most cases, surgical decompression through burr hole or craniotomyis warranted. Near complete evacuation of the purulent material and appropriate long-term intravenous antibiotics are necessary for a gratifying outcome.

Background: Medulloblastoma has recently been found to consist of 4 molecularly and clinically distinct subgroups: WNT, Sonce hedgehog (SHH), Group 3, and Group 4. Deregulated microRNA expression is known to contribute to pathogenesis and has been shown to have diagnostic and prognostic potential in the classification of various cancers., Methods: Molecular subgrouping and microRNA expression analysis of 44 frozen and 59 formalin-fixed paraffin embedded medulloblastomas from an Indian cohort were carried out by real-time RT-PCR assay., Results: The differential expression of 9 microRNAs in the 4 molecular subgroups was validated in a set of 101 medulloblastomas. The tumors in the WNT subgroup showed significant (P < .0001) overexpression of miR-193a-3p, miR-224, miR-148a, miR-23b, and miR-365. Reliable classification of medulloblastomas into the 4 molecular subgroups was obtained using a set of 12 protein-coding genes and 9 microRNAs as markers in a real-time RT-PCR assay with an accuracy of 97% as judged by the Prediction Analysis of Microarrays. Age at diagnosis, histology, gender-related incidence, and the relative survival rates of the 4 molecular subgroups in the present Indian cohort were found to be similar to those reported for medulloblastomas from the American and European subcontinent. Non-WNT, non-SHH medulloblastomas underexpressing miR-592 or overexpressing miR-182 were found to have significantly inferior survival rates, indicating utility of these miRNAs as markers for risk stratification., Conclusions: The microRNA based real-time PCR assay is rapid, simple, inexpensive, and useful for molecular classification and risk stratification of medulloblastomas, in particular formalin-fixed paraffin embedded tissues, wherein the expression profile of protein-coding genes is often less reliable due to RNA fragmentation.

Facial schwannomas or neuromas are rare entity. They often are confused with vestibular schwannomas on imaging, especially if they are limited to the cisternal segment of the facial nerve. Awareness regarding this entity is paramount for the early diagnosis and correct management which may differ from patient to patient. We share the different clinical presentations of this rare benign tumour and discuss their management strategies in light of the affected segment of the nerve. The results were analyzed along with review of literature. Three cases of facial schwannomas were analyzed retrospectively during last 4 years and their presentation, imaging, preferred surgical approaches, intra-operative findings and post grafting results are discussed. All three patients underwent surgical excision with sural nerve cable grafting and have no recurrence till date. However, the facial paresis remained the same in one of the cases while improvement was observed in two patients. The improvement was delayed in one patient as documented by electromyography of facial muscles. Facial schwannomas are slow growing tumours with low incidence. Usual presentations can sometimes be masked. Appropriate management decision needs to be arrived after considering three determinants i.e. the patient's age, hearing status and the severity of facial paresis (House-Brackmann grading). Nerve reconstruction after excision should be performed in each case and sometimes the results may be delayed. It is thus important to keep a close surviellance during the follow up and to perform the electrophysiological tests frequently so as to detect the earliest signs of regeneration (which can be delayed up to 18 months).

Glioblastoma Multiforme (GBM) presents a major challenge for a neurosurgeon as the most common primary malignant tumour of the central nervous system. The median life span after the diagnosis still remains between 6 months to 1 year even after gross total excision of the tumour. However, few patients survive long and develop recurrence after a substantial time interval. The exact reason behind the long term survival in GBM cases remains obscure. However, few predictors have been identified of late. Young age, p53 positivity, O6-methylguanine methyltransferase (MGMT) methylation, aggressive surgical resection and a good pre-operative Karnofsky Performance Score (KPS) have been identified with good survival rates in these select cases. Immunohistochemistry forms an integral part of a glioblastoma work up and it must be done in each and every case as it may provide crucial insights regarding prognosis. We report a rare case of glioblastoma multiforme with a long term survival of 20 years. This patient developed a frontal cystic tumour bilaterally in these 20 years and is still leading an active life. The clinical summary, imaging, histopathology, immunohistochemistry along with relevant literature have been discussed.
