RESUMEN
Brain tumors in children represent the second most frequent tumors in this age group after hematologic malignancies. We highlight the demographic pattern after retrospective analysis of brain tumors in children from geographically and ethnically distinct Kashmir Valley managed in our center between 2000 and 2009. We had a total of 248 pediatric patients with brain tumors. The parameters analyzed were age, gender, location of tumors and histopathological subtypes as well as WHO grade of tumor. We also did a comparison between the frequencies of common varieties of tumor in the first and second 5-year periods. We found that 111 tumors (44.75%) were supratentorial, and 137 (55.25%) were infratentorial. The male-to-female ratio was 1.4:1. The proportions of low-grade and high-grade tumors were 60 and 40%, respectively. The most common tumor in our series was astrocytoma. The most common tumors in the supratentorial and infratentorial compartments were craniopharyngioma and medulloblastoma, respectively. Our experience reflects a different demographic profile of pediatric brain tumors as compared with other regions of the world.

AIM: To study the clinicopathological aspects of primary CNS lymphoma in immunocompetent patients. MATERIAL AND METHODS: Sixteen patients with primary CNS lymphoma were analyzed for their clinico-pathological characteristics and followed-up for the treatment and subsequent management in Neurosurgery, and Medical and Radiation Oncology. RESULTS: The fronto-parietal region was the commonest location of CNS lymphoma; four cases of cerebellar lymphoma were seen. Our patients were relatively young with a mean age of 48 years and an age range of 35-60 years. Females outnumbered males with a ratio of 2.7:1. The commonest presentation was focal neurological-deficits and features of raised intracranial pressure. All the patients histologically had diffuse large B-cell lymphoma. Radiologically, most presented as disc-enhancing lesions. Two patients had multiple lesions. Most of the patients (10) died within a mean of 4.4 months (range 2 weeks-16 months). CONCLUSION: Primary CNS lymphoma is seen in immunocompetent patients as well. Relapse is common after treatment and the overall prognosis is unfavorable.

Papillary tumor of the pineal region (PTPR) is a rare grade II to III pineal lesion. These tumors mostly occur in adults, only rarely in children, with six cases in children under the age of 16 years (10.2%) up to now. We report the case of a 5-year-old male child presenting with worsening headaches, abnormally enlarged head since birth and visual disturbances. Imaging reveals a mass in the region of the pineal gland. The third and lateral ventricles were enlarged. The patient underwent a gross-total surgical resection of pineal mass through a suboccipital supracerebellar approach and tissue sent for histopathological examination and an available immunohistochemical workup has been done which confirmed the diagnosis of papillary tumor pineal region. This case highlights the histopathological features, imaging along clinical presentation similar to those in the original description of this rare entity PTPR. More studies are required to determine the prognosis and standard treatment protocol of this rare entity.
RESUMEN
CONTEXT: Gliomas are the most common brain tumors. In addition to conventional magnetic resonance imaging (MRI) techniques, a variety of new techniques offers more than the anatomic information. The new MRI techniques include perfusion-weighted imaging (PWI) and diffusion-weighted imaging (DWI). AIMS: The aim of this study is to assess the sensitivity, specificity, predictive value, and accuracy of diffusion- and perfusion-weighted MRI in the preoperative grading of gliomas. SETTING/DESIGN: The study was conducted in the Department of Neurosurgery, Pathology, and Radiodiagnosis, Sher-e-Kashmir Institute of Medical Sciences, Kashmir, India, which is the only tertiary care neurosurgical center in the state. It was a prospective study. PATIENTS AND METHODS: Thirty-one consecutive patients with gliomas were included in the study. All the patients were evaluated by a standard conventional contrast-enhanced study on Siemens 1.5 Tesla MRI. In addition to the standard MRI, diffusion- and perfusion-weighted MRI were also performed. The histopathological grading of the tumor was done as per the WHO classification of 2007. The sensitivity, specificity, predictive value, and accuracy of diffusion- and perfusion-weighted MRI in determining tumor grade were calculated. Comparison was done between PWI, DWI findings, and WHO histopathological grading. ANALYSIS METHOD: The statistical analysis was done using the Statistical Package for the Social Sciences, and receiver operating characteristic curves were used to estimate sensitivity, specificity, and accuracy. RESULTS: The overall sensitivity of PWI (with regional cerebral blood volume cutoff of 1.7) in the preoperative assessment of high-grade gliomas was 82.6% and specificity was 75%, the positive predictive value (PPV) was 90.48%, and the negative predictive value (NPV) was 60%. The overall accuracy was 80.65%. In case of DWI, the sensitivity was 69.57% and the specificity was 75%, and the PPV and NPVs were 88.8% and 46.15%, respectively. The overall accuracy was 71%. CONCLUSION: Our results clearly show higher accuracy of diffusion- and perfusion-weighted MRI in assessment of glioma grade as compared to conventional MRI. This information can prove very useful for the operating neurosurgeon in preoperative assessment and surgical planning. Postoperatively, the neuropathologist can also benefit from such information.
RESUMEN
BACKGROUND: Meningiomas comprise 15%-20% of all primary intracranial tumors. They are generally benign tumors, and most patients are cured after surgery and remain free of recurrence. However, some tumors behave in an aggressive manner, and patients develop local recurrence or metastasis. Overall prognosis is good. PATIENTS AND METHODS: This is an 11-year retrospective study conducted in the Departments of Pathology and Neurosurgery at Sheri-I-Kashmir Institute of Medical Sciences, Kashmir, India. Besides the demographic profile, the parameters analyzed were location of tumor on imaging, histopathological subtype, and grade of tumor according to the 2007 WHO classification and recurrence at follow-up. RESULTS: A total of 254 patients were included in our study, of which 205 (80.7%) were brain meningiomas and 49 (19.3%) were spinal, with an overall female: male ratio of 2:1. Female: male ratio was more in spinal meningiomas, 15.3:1. Most of our patients were in the 4-6th decade of life with a mean age of 48 years (range: 5-73 years). Meningothelial meningioma was the most common histological type. Of ten patients who showed recurrence, seven cases showed only recurrence, but no progression to higher grade and three cases showed recurrence with progression by one WHO-grade. We also noticed that recurrence was higher in Simpson Grades II and III. CONCLUSION: Meningiomas are common in females and most of the meningiomas do well after surgery. The recurrence rate was 3.93% in our study and Simpson grade of tumor excision and histopathological grade contribute significantly to the recurrence of the tumor.
RESUMEN
BACKGROUND: Posterior fossa EDH is an uncommon entity, accounting for only 4% to 12.9% of all EDHs It has a characteristic clinical presentation, which if detected can be life-saving. METHODS: We sought to study the demographic features of patients with PFEDH and assess the clinical and radiologic predictors of the outcomes of as well as evaluate the various treatment modalities for this disease. We carried out a retrospective analysis of the cases of 61 patients with PFEDH who were admitted to the National Institute of Mental Health and Neurosciences (Bangalore, India) from 1991 through 2002. We analyzed various parameters and applied Fisher's exact test for statistical analysis. RESULTS: Mostly male individuals were affected with PFEDH. Their GCS score at admission and the presence of hydrocephalus as detected by CT scan determined the outcome of the patients. The children had better outcomes than did the adults. Patients with a good GCS score could be managed conservatively. CONCLUSIONS: Posterior fossa EDH is rare. The PF is an unfavorable location of a hematoma. Good GCS scores have a favorable prognosis. Children have better outcomes than do adults, and the presence of hydrocephalus on CT scan is an ominous sign.

INTRODUCTION: Traumatic brain injury (TBI) in children is a significant cause of morbidity and mortality worldwide. Falls are the most common type of injury, followed by motor vehicle-related accidents and child abuse. AIMS AND OBJECTIVES: The aim and objective of this study was to elucidate the various modes of injury, prognostic factors, complications, incidence of various modes of injury, and outcome in TBI in pediatric population. MATERIALS AND METHODS: Patients with TBI, 18 years or less in age, managed in our Department of Neurosurgery, over a period of 2 years, were studied prospectively. Detailed history, general physical examination, systemic examination, and central nervous system examination including assessment of Glasgow Coma Scale score (GCS) and pupillary size and reaction were noted in every patient. Based on GCS, patients were divided into mild head injury (GCS 13-15), moderate head injury (GCS 9-12), and severe head injury (GCS ≤8) categories. All the patients were subjected to plain computed tomography (CT) scan head, and CT findings were noted. Patients were managed conservatively or surgically as per the standard indications. The outcome of all these patients was assessed by Glasgow outcome scale and divided into good (normal, moderate disability) and poor (severe, vegetative, dead) outcome. Outcome was assessed in relation to age, sex, GCS, pupil size and reaction, CT scan features, intervention, and associated injuries. RESULTS: A total of 403 patients aged between 1 day and 18 years were included in the study comprising 252 males (63%) and 151 females (37.75%). The common modes of injury were fall 228 (56.6%) followed by road traffic accidents 138 (34.2%), assault 10 (2.5%), and others 27 (6.7%) which include sports injury, hit by some object on head, and firearm injury. Majority of our patients had a GCS of 13-15 (mild head injury), 229 (57.3%), followed by 9-12 (moderate head injury) 119 (29.8%), followed by 8 or less (severe head injury) 52 (13%). In group of patients in the category of GCS ≤ 8, poor outcome was seen in 65.3%, followed by patients in group GCS 9-12 at 2.45% succeeded by group of patients with GCS 13-15 at 2.6%, which was statistically significant (P < 0.0001). A total of 354 (87.8%) patients had normal pupils, 37 (9.2%) had anisocoria, and 12 (3%) patients had fixed dilated pupils. Fixed dilated pupil had poor outcome (100%) followed by anisocoria (40.5%) and normal pupils (16%), which was statistically significant (P < 0.0001). CONCLUSION: Majority of children who suffer from TBI do well although it still continues to be a significant cause of morbidity and mortality in them. The outcome is directly related to the neurological status in which they present to the hospital.
RESUMEN
INTRODUCTION/BACKGROUND: Neural tube defects (NTD) are the most common congenital malformations affecting the brain and spinal cord and have a multifactorial etiology. Genetic and environmental factors have been found to cause these defects, both individually and in combination. AIMS AND OBJECTIVES: The aim of this study was to determine the incidence, types, demographics, risk factors, and other associated anomalies relevant to NTDs in Kashmir Valley. MATERIALS AND METHODS: A 2-year hospital-based prospective study was carried out from November 2013 to October 2015. A detailed history of the mother was taken along with detailed clinical examination of neonate including measurement of head circumference and checking the status of fontanella, whether - lax/full/bulging/or tense, type of NTD. Investigations that were done included were X-ray skull: Anteroposterior (AP) and lateral, X-ray spine: AP and lateral, ultrasonography abdomen, magnetic resonance imaging: Spine and brain. RESULTS: The total number of babies with NTD's was 125 with an overall incidence of 0.503. District Kupwara was having the highest incidence (1.047) and district Srinagar the lowest incidence of NTD's (0.197). The majority of NTD's (116 cases, 92.8%) were found in the rural areas. Among the different types of NTD's, spina bifida had an incidence of 0.342 (85 cases, 68%), and anencephaly had an incidence of 0.113 (28 cases, 22.4%). There was a slight preponderance of females over males with NTD's. There were70 females (56%) and 55 males (44%) respectively with a male:female ratio of 0.8:1. CONCLUSIONS: The incidence rates of NTDs are very high for Kashmir Valley. Geographical distribution of NTDs at this place confirms a relationship between the socioeconomic status, educational status, maternal age and environmental factors for the development of an NTD. The results of this study point to the importance establishing a health policy to prevent NTDs in Kashmir Valley.

The results of this study point to the importance establishing a health policy to prevent NTD in Kashmir Valley.
RESUMEN
Brain tumors are not rare in children. The common brain tumors in children are medulloblastomas and craniopharyngiomas. Intraparenchymal meningiomas are very rare. We report a case of intraparenchymal meningioma in a child who was operated with a preoperative impression of a primitive neuroectodermal tumor.
RESUMEN
AIM: To analyze the analysis of recurrence rates of single versus double burr holes in patients with subacute and chronic subdural hematomas. MATERIAL AND METHODS: The study was a prospective randomized controlled trial on patients with subacute and chronic subdural hematomas. Collections with membranes or septae were excluded from the study. A written consent was taken from the patient or patient party after explaining the procedure. A total of 254 patients were enrolled in the study over a period of 18-months in the Department of Neurosurgery, Sheri-Kashmir-Institute of Medical Sciences, Srinagar, Kashmir. RESULTS: Recurrence rates in single and double-burr-hole groups were 6.15% and 4.83% respectively, which was not statistically significant. CONCLUSION: Most of the subdural hematomas can be dealt by single burr-hole drainage.

Tubercular meningitis constitutes an important cause of morbidity and mortality in developing countries, and various factors determine its outcome. We studied demographic and clinical profiles of childhood tubercular meningitis, and identified predictors of outcome. This prospective study was performed in 65 children aged ≤ 18 years, hospitalized with a diagnosis of tubercular meningitis. Boys outnumbered girls. Most patients presented with a poor clinical grade. Headache and vomiting comprised common features. Cerebrospinal fluid was characterized by predominant lymphocytosis. Many patients were diagnosed for Mycobacterium tuberculosis via polymerase chain reaction. Hydrocephalus comprises a common finding via computed tomography. Low Glasgow Coma Scores, seizures, basal exudates, and infarcts predict outcomes. Children with headaches, fevers, and altered sensorium should be investigated promptly for tubercular meningitis. Timely intervention may lead to early diagnoses and reductions in morbidity and mortality.

Traumatic pseudoaneurysm of the middle meningeal artery is rare and is associated with high mortality. Skull fracture is usually an associated feature of this entity. An elderly male was brought to our hospital in a stage of coma. The details of ictus were not known. The Glasgow coma scale score was 9/15. Examination revealed a pseudo-aneurysm arising from the posterior branch of the left middle meningeal artery which was excised. The case is presented for its rarity and its characteristic radiology. Traumatic pseudoaneurysm of middle meningeal artery is rare. It is important to recognize this treatable entity.

Epidural hematomas which are located at the vertex are rarely seen and form a small percentage of total epidural hematomas. Tearing in the superior sagittal sinus is the usual cause of an epidural hematoma located in the vertex. The clinical features of this entity are non-specific; hence, localization of the lesion is difficult. We report an adult who was hit by a motorcycle and was initially discharged from the hospital as a case of concussional head injury. He returned back with raised intracranial pressure symptoms, so a CT scan was done but was misinterpreted, and he reported one week later with bilateral abducent nerve palsy. Magnetic resonance imaging confirmed vertex EDH for which he was operated.These hematomas are seen rarely and can be interpreted as an artifact. Its recognition is important because it has an excellent prognosis. We concluded that all head injury patients should get high axial cuts on the CT scan, and any degree of suspicion should prompt a neurosurgeon to investigate further with coronal CT scan or MRI.

BACKGROUND: We endeavored to analyze patients of subacute and chronic subdural hematomas studied in a 4-year period at the Sher-i-Kashmir Institute of Medical Sciences, Kashmir, India. METHODS: The study was a retrospective analysis of 1181 patients of subdural hematomas. Demographic characteristics, clinico-radiologic features, operative modalities, and outcome were studied. Acute subdural hematomas were excluded from the study. RESULTS: The mean age was 60.4 ± 12.4 and males outnumbered females. Chronic subdural collections were more common than subacute subdural hematomas and left side predominated. Two burr holes with closed-system drainage was used in most patients. Incidence of postoperative seizures is very low. Overall recurrence rates were low; however, multilocular hematomas had the highest incidence of recurrence. Morbidity and mortality were 7.53% and 2.96%, respectively. Preoperative neurologic grade correlated with outcome. CONCLUSIONS: Subdural hematomas are common in elderly males. Preoperative neurologic grade dictates the outcome. Multilocular hematomas have a higher chance of recurrence. Craniotomy should be reserved for recurrent hematomas, and there may be a scope of craniotomy for multilocular chronic subdural hematomas at the outset. Antiepileptic prophylaxis is not routinely recommended.

Sellar and suprasellar tuberculomas are rare. Patients with these lesions usually experience headache, vomiting, and hypofunction of pituitary gland; imaging reveals an enhancing sellar-suprasellar mass. We report 2 rare cases of sellar-suprasellar tuberculomas in children aged 8 and 6 years. One child presented with features of headache and vomiting, and the other presented with posterior pituitary dysfunction. In both cases, imaging revealed sellar-suprasellar masses. Both cases were multidrug-resistant tuberculomas. We discuss sellar-suprasellar tuberculomas, a rare form of neurotuberculosis in the background of an overall increase in multidrug-resistant tuberculosis, especially in children.

BACKGROUND: Lhermitte-Duclos disease is typified by a hamartomatous lesion of the cerebellum. It is usually seen in females. The usual presentation is of raised intracranial pressure along with cerebellar signs. CASE REPORT: We report an 18-year-old female patient who presented to us with history of headache and gait ataxia and was observed to have Lhermitte-Duclos disease with cervical cord syrinx on imaging. DISCUSSION: To our knowledge this is the fifth case of Lhermitte-Duclos disease with syringomyelia in the pediatric age group. The treatment of this condition is decompression of the lesion. Malignant transformation never occurs and the prognosis is excellent.

AIM: Primary sacral lymphoma is rare. It usually presents in elderly males as low back ache and radiculopathy. CASE REPORT: We hereby report a case of primary sacral lymphoma in a 53-year-old male who presented with low back pain. Imaging showed a sacral lesion which on histopathology proved to be a non-Hodgkin's lymphoma of B cell lineage. MATERIAL AND METHODS: The case is presented for its rarity and for the reason that it mimicked a primary bone tumor. Its recognition is important because it has an excellent prognosis. CONCLUSION: Primary sacral epidural lymphoma should be considered in the differential diagnosis of a sacral mass.

OBJECT: The aim of this study was to analyze the correlation of hypodensity in extradural hematomas on CT with the clinical profile in pediatric patients. This is the only study available in this age group. METHODS: This was a prospective study conducted over a period of 3 years in which all children 18 years old or younger with a diagnosis of cranial extradural hematoma were included. The patients were allocated to 2 groups: those with mixed-density clots (17 cases) and those with classically hyperdense clots (52 cases). A comparative analysis between the 2 groups was conducted. RESULTS: Patients with mixed-density clots presented earlier to the hospital, had poor Glasgow Coma Scale scores at admission, exhibited large clot volumes, had a high incidence of active bleeding at surgery, and had increased morbidity and mortality as compared with the patients with hyperdense extradural hematomas. CONCLUSIONS: Early recognition and rapid evacuation of the mixed-density clot with restoration of hemostasis may result in a decline in morbidity and death in children with this entity.
