The value of computer axial tomography (CAT) in cranio-cerebral malformations

Abstract

Cranio-cerebral malformations commonly present in three ways: (1) with a visible structural defect; (2) with symptoms of neurological abnormalities but without evidence of raised intracranial pressure; (3) with macrocephaly or signs of raised intracranial pressure. The large contribution made by computed axial tomography to the diagnosis and management of these cases is discussed in relation to a series of 217 patients. Invasive studies were performed in only 55 cases mainly to obtain further anatomical information prior to surgery.
