Craniopharyngioma with abnormal vasculature

Computed tomography with craniopharyngiomas: a review

A retrospective study of the computerized tomographic (CT) examinations of 20 children and 13 adults with craniopharyngiomas was undertaken, with special attention paid to the densitometric characteristics of the tumors (contrast enhancement and presence of cysts and calcifications). The aim was to quantify these characteristics and to assess their diagnostic reliability, both alone and together. In suprasellar tumors al three characteristics were present in 75% of the cases, with a diagnostic accuracy of 100%; two were present in 20.6%, with a diagnostic accuracy of 85%; and one was present in 3.4%, with a diagnostic accuracy of 50%. The unusual densitometric presentations of intrasellar tumors are discussed.

Neuroradiological manifestations of suprasellar pituitary adenomas, meningiomas and craniopharyngiomas

The radiological manifestations of 16 pituitary adenomas, six meningiomas and 14 craniopharyngiomas were reviewed. The differential diagnosis of these tumors is possible with a few exceptions when skull radiography, CT, angiography and metrizamide cisternography are carefully evaluated. Prolonged injection angiography (PIA) is particularly important for demonstrating the contours of pituitary adenomas and meningiomas. Metrizamide cisternography is indicated when the tumor contours are obscure using PIA, or when the differential diagnosis is uncertain.

Unusual angiographic manifestations of craniopharyngioma: a case report

A craniopharyngioma with two unusual manifestations, a dense capsular stain and occlusion of the internal carotid artery, is reported. Neither of these findings appear to have been reported previously. Explanations for these unusual phenomena are offered.
