Role of Pericardial Patch in Neurosurgery: Institutional Experience.

Introduction: Dural closure is an important part of neurosurgery, failure which may lead to wound infection, pseudomeningoceles, meningitis, severe morbidity to a patient, and even mortality. In cases where primary dura closure is not possible, a bovine pericardial patch is a good alternative with the benefits of suturability and the ability to provide watertight closure, hence preventing Cerebrospinal Fluid (CSF) leak. The present study demonstrates the use of the bovine pericardial patch in both cranial and spinal disorders for dural closure as well as for transposition technique in microvascular decompression.

Extra-Axial Third Ventriculostomy Through Lamina Terminalis with Multiple Cisternostomies - Rescue Surgery for Patients with Failed Shunt Surgeries and Hydrocephalus.

Background And Aim: Contemporary management of hydrocephalus involves various modes of cerebrospinal fluid (CSF) diversion, including shunt surgery and endoscopic ventriculostomy. However, there are times when either of these procedures have either failed or are not feasible. Highly invasive procedures aimed at internal CSF have been described previously, which, with the aid of modern microsurgical techniques, can be attempted in cases with very limited options.

Intraoperative Ultrasound an Economical Tool for Neurosurgeons: A Single-Center Experience.

Background: Over the past decade, the use of intraoperative image guidance in neurosurgery has gradually gained in importance. Apart from some sophisticated and very expensive techniques, intraoperative ultrasound (IOUS) is a simple and economical technique that allows the surgeon to localize deep-seated lesions under a real-time ultrasonic image display without dissection. The purpose of this study was to present our own preliminary experiences in various (n=1250) neurosurgical procedures carried out at our tertiary care centre in a developing country.

Primary Multiple Intracranial Extradural Hydatid Cysts: A Rare Entity Revisited.

Human hydatid disease is caused by Echinococcus granulosus. Central nervous system (CNS) echinococcosis is rare with less than 4% of cases of hydatid disease have CNS involvement. intracranial extradural hydatid cysts are rare and less than 11 case have been reported in literature.

Pediatric Isolated Cortical (Ectopic) Anaplastic Ependymoma.

Ependymomas are tumors derived from ependymal cells lining the ventricles or from the central canal of the spinal cord. It usually arises in the ventricles with extra ventricular extension. Less than 15 cases of purely cortical ependymomas are reported.

Mature Cystic Teratoma of Dorsal Spinal Cord in Adult: An Unusual Lesion.

Teratomas are a type of multipotential cell tumor that contain a mixture of multiple germinal layers formed by normal organogenesis and reproductive tissues the incidence of intracranial teratomas is low, approximately 0.5-2.2% of all intracranial tumors.

Primary pleomorphic xanthoastrocytoma of the spinal cord: A case report and review of literature.

Primary pleomorphic xanthoastrocytoma (PXA) of the spinal cord is a rare slow growing tumor. To our knowledge, only five such cases have been reported in the literature till date. We report the clinical, radiological, and histopathological features of a spinal PXA in a 23-year-old female previously operated 5 years back for a spinal tumor, presented with weakness in lower limbs, sphincter incontinence and low back pain.

Recurrent intraventricular meningioma with malignant transformation.

Benign meningioma undergoing a malignant transformation (to a chondrosarcoma) in intraventricular location is very rare and this is first case report to best of our knowledge. Herein, we report a rare case of malignant transformation of a benign intraventricular meningioma with relevant literature.

Primary aneurysmal bone cyst of the petrous temporal bone: A case report and review of literature.

Aneurysmal bone cyst (ABC) arising in the petrous portion of the temporal bone is a rare entity with only five such reported cases in the literature. We report the case of a 28-year-old man who presented with a tender swelling in the right preauricular region with right ear discharge and conductive hearing loss of 4 years' duration. Computed tomography and Magnetic Resonance imaging showed a destructive lesion in the right petrous bone with cavitation consistent with the diagnosis of ABC.

Atypical rhabdoid tumor of lateral ventricle: Report of an unusual tumor.

Supratentorial atypical teratoid rhabdoid tumors (AT/RTs) of infancy and childhood are rare, highly malignant neoplasms, most common in the first 2 years of life. In spite of multiple treatment regimens consisting of surgical resection, radiation therapy, and multi-agent chemotherapy, the prognosis is very poor. The majority of these tumors are located in the cerebellum, cerebellopontine angle, pineal gland, spinal cord, and the suprasellar region; supratentorial location is relatively uncommon, and the intraventricular location is extremely rare.

A rare case of an isolated intraventricular tuberculoma with a dismal outcome: an unusual location of a common pathology and lessons learnt.

Isolated involvement of the ventricle by tuberculosis is extremely rare and only nine cases have been reported till now. We report a 13-year-old immuno-competent boy who presented with features of raised intracranial pressure with altered sensorium. Computed Tomography showed a ring enhancing intraventricular lesion with obstructive hydrocephalus.

Congenital orbital teratoma up to posterior fossa.

Congenital orbital teratoma is a rare condition which presents as marked proptosis of eyeball in a newborn. It is rapidly progressive with secondary damage to eyeball due to pressure effect. This case presented by us is of interest due to radiological features and rarity of this tumor extending into posterior fossa.
