Intraventricular third ventricle meningiomas are very rare. Fourteen cases have been previously reported. We present a case of third ventricle meningioma, and discuss aetiology, pathology, symptoms, signs, position in the ventricle, and surgical approaches.
Four cases of brain tumour associated with intracranial aneurysm are presented, and the available literature is reviewed. The association of brain tumours and arterial aneurysms is not well documented in neurosurgical literature. Reports of the association of giant aneurysms with brain tumours are rare. We could find only five such cases, and one of our cases is the sixth. The operative mortality of the patient with coexisting brain tumour and cerebral aneurysm is high. Two of our cases died postoperatively, one from pre-existing cardiac disease, and the other from hypothalamic vascular insuffiency related to surgery.
A single venous shunt obstructing the aqueductus of Sylvius was treated by interventriculostomy. A passage for CSF was obtained between the third and fourth ventricles. The catheter which was left in the aqueduct collapsed the malformation, possibly preventing a future haemorrhage. A Simple rubber catheter in the aqueduct of Sylvius has been well tolerated by the patient for 15 years.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
