Analysing 12 cases of cavernous sinus meningiomas the authors conclude that: the clinical history is characteristic; CT scan has proved to be more sensitive than carotid angiography in detecting small lesions. However in large lesions the vascular supply pattern is the only feature that exactly identifies the site of the lesion. Both angiography and CT scan allow a near definitive diagnosis of meningioma; because of their location it is almost always impossible to remove these tumours completely. Actually the best treatment is a piecemeal subtotal microsurgical removal via a subtemporal approach. Radiotherapy is indicated for partially resected lesions. On the basis of the revision of the anatomy of this region and looking forward to a widespread use of the Cavitron in neurosurgery, a more radical approach to this lesion is foreseen.
A case of congenital absence of the right internal carotid and of the left vertebral arteries, associated with an aneurysm on the anterior communicating artery, is reported.Some aspects of this anomaly are reviewed.Keywords: Internal carotid artery; vertebral artery; agenesis of cerebral arteries; aneurysm; subarachnoid haemorrhage.Congenital absence of the internal carotid artery is unusual in man. In 1977 Servo summarized 29 cases (including his own) of total unilateral, and 7 cases of total bilateral, absence of this vessel. Some cases were certainly not reported, others have no doubt been recognized since 1977 4, 13. About 40 cases of internal carotid agenesis are reported in the literature. We wish to describe a new case, and briefly review some aspects of this anomaly.
Case ReportA 38-year-old housewife had been in good general health until a month previously, when she complained of sudden onset of severe headache soon after getting up in the morning. She vomited repeatedly and headache spread down to the nape of the neck. A few days later bilateral palpebral ecchymoses appeared, so that she was brought to the local Hospital. On admission, she complained of headache, and had a stiff neck and a mild left hemiparesis. The optic fundi were haemorrhagic. A lumbar puncture produced bloody cerebrospinal fluid. The patient was then referred to the University Hospital with the diagnosis of
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.
