BACKGROUND We describe three cases of extradural haematomas (EDHs) and their management, focusing on operative and non-operative treatment. We also review the available literature from the past three decades as well as the guidelines for the management of EDH. An algorithm is formulated based on different factors, including the clinical course of the(More)
Glioblastoma multiforme (GBM) is a highly aggressive brain cancer with extremely poor prognostic outcome despite intensive treatment. All chemotherapeutic agents currently used have no greater than 30-40% response rate, many fall into the range of 10-20%, with delivery across the blood brain barrier (BBB) or chemoresistance contributing to the extremely(More)
Background Cerebrospinal fluid (CSF) sampling is performed during ventriculoperitoneal (VP) shunting procedure surgery for early detection of infection. We have performed a retrospective study to determine whether routine intraoperative CSF sampling at new VP shunt insertion has predicted shunt infection or changed subsequent surveillance or management.(More)
The field of neuroendoscopy is rapidly expanding with increasing indications for endoscopic third ventriculostomy (ETV). As a treatment for hydrocephalus, ETV has the advantage of providing a more physiological cerebrospinal fluid diversion without shunt hardware which reduces the risk of recurrent infection and malfunction. The success rate of ETV has been(More)
The authors describe the case of a 3-year-old boy with a giant congenital vertex hemangioma who underwent presurgical embolization with Onyx (ethylene-vinyl alcohol copolymer dissolved in dimethyl sulfoxide) and Glubran ( N-butyl-2-cyanoacrylate). This vascular tumor had no intracranial vascular communication as assessed by pre-embolization MRI and catheter(More)
Renal cell carcinomas (RCC) are characterised by a tendency to metastasise widely, often while remaining occult. Intramedullary spinal cord metastases (ISCM) from RCC may be the presenting feature of the disease or present at any time in the disease course. This case report discusses an ISCM from RCC which became manifested at the time of resection of the(More)
Idiopathic intracranial hypertension is a headache syndrome with progressive symptoms of raised intracranial pressure. Most commonly, it is a slow process where surveillance and medical management are the main treatment modalities. We describe herein an acute presentation with bilateral sixth nerve palsies, papilloedema and visual deterioration, where acute(More)
Cerebral cavernous malformation (CCM) in infants tends to have genetic predisposition. These cavernomas have a progressive course of events and associated neurological symptoms with increase in age. They most commonly present with seizure and syndrome of increased intracranial pressure comprising of headache, vomiting and focal neurological signs. We(More)
OBJECTIVE The aim of this study was to assess the outcome of neurosurgical treatment in children with bleeding diathesis and also to evaluate the current management plan applied in the authors' service. METHODS The authors retrospectively analyzed all cases in which neurosurgical procedures were performed in pediatric patients presenting with intracranial(More)
Central nervous system (CNS) angiosarcoma, both primary and secondary, is an exceptionally rare malignant tumor. The behaviour of angiosarcoma is one of rapid progression with early metastatic spread but as with all sarcomas, the primary site may not clinically evident by the time metastases develop. Identification of the primary site of origin is masked by(More)
