XXXX . A review of 10 cases of the National Hospital, Queen Square (1974-1985) with reference to the literature.

Ten @entity1 with histologically verified @entity1653 were treated between 1974 and 1985. There were eight female and two male @entity1 , ranging in age from 25 to 72 years with a mean age of 45.5 years. @entity10 and disturbed mentation were the most common presenting symptoms whereas corticospinal disturbance, altered mentation and homonymous @entity1805 were the most common signs on formal neurological examination. Papilloedema was demonstrable in 50% of cases and evidence of @entity2026 was apparent in 60% of @entity1 with lesions affecting their dominant hemisphere. A single instance of drop attack occurred in a @entity1 harbouring a third @entity67 . Computed tomography, with and without contrast enhancement, and angiography were employed in all cases and proved highly sensitive and specific for @entity5 localisation and tissue diagnosis. In addition, angiography proved invaluable in demonstrating both vascular supply and the effects imposed upon the surrounding cerebral vasculature by @entity5 mass and @entity1276 . Nine @entity5 occurred in the lateral ventricular trigone of which 5 were left-sided. A tenth @entity5 was located in the third ventricle. Twelve resections were performed in 10 @entity1 . One @entity1 was found to have a highly malignant @entity1653 which recurred within 10 weeks of the original surgery and proved fatal shortly thereafter. A second @entity1 whose initial resection was subtotal had a recurrence 3 years postoperatively which was totally resected. Lesions were approached most commonly through the posterior middle or posterior inferior temporal gyri. On 3 occasions a right posterior middle frontal gyrus approach was used and in one case a posterior parieto-occipital cortical incision was employed.(ABSTRACT TRUNCATED AT 250 WORDS)
