Intracranial Pearly Tumors

Abstract

The findings in computed tomography (CT) and other radiological examinations in nine histologically proven cases of intracranial pearly tumors are presented. The CT findings include a low density lesion with no enhancement after contrast medium injection and in some cases a lesser degree of mass effect than would be expected from the size and site of such lesions. Pneumoencephalography is superior to CT in detecting suprasellar pearly tumors when they are isodense with the cerebrospinal fluid.
