[Results of serial CT in the evaluation of the sellar region].

The article reports on the methodology and results of serial CT in differential diagnosis of intrasellar and parasellar structures, based on 32 examinations. Whereas the normal pituitary gland displays an approximately equal contrast medium performance as the pituitary adenomas and recurrent tumours, different types of tissue such as those of tumours, vascular structures and postoperative scans can be well differentiated from each other by means of serial CT. Aneurysms can be safely differentiated from intracranial tumours, such as meningiomas, only via serial CT.
