XXXX : diagnosis with special reference to computerised tomography.

@entity1 @entity548 @entity5 @entity439 @entity438
The clinical presentation, radiological investigations and surgical management of 11 @entity1 with @entity438 (greater than 2.5 cm) have been reviewed. Most @entity1 had signs and symptomd @entity548 . The most helpful plain film finding was intracranial calcification. This varied from a mere fleck to the classical curvilinear variety. Computerised tomography (CT) scans were available on all 11 @entity1 . All showed a space-occupying lesion of high density. Two types of enhancement were seen following intravenous contrast medium, (a) homogeneous and (b) rim enhancement with or without a patchy increase in density centrally. The CT appearances in some of the cases resembled those shown by other lesions such as @entity5 . Arteriography in almost all cases demonstrated the @entity439 but often under-estimated its size. On two occasions the @entity439 did not fill and the nature of the lesion demonstrated on the plain CT remained unconfirmed. Direct surgical attack rather than carotid ligation was the operation of choice. Most @entity1 responded very well to this treatment.
