Diagnosis of sellar and parasellar lesions by computed tomography.
Suspected lesions in and around the sella were examined by CT in 129 cases. The diagnostic accuracy and various technical aspects of the method are described. The mean attenuation and enhancement after administration of contrast material are evaluated in craniopharyngiomas, chromophobe adenomas, meningiomas, aneurysms, dermoid cysts, an arachnoid cyst and a glioma. the choice of collimator and its use in relation to sellar dimensions, particularly the sellar depths, are emphasized.
