Computed Tomography in the Evaluation of the Supraclinoid Arteries in Suprasellar Pituitary Gland Tumors

Abstract
The demonstration of the supraclinoid arteries at CT [computed tomography] in 38 patients with suprasellar lesions was evaluated. The anterior cerebral artery was visible in 8%, the other supraclinoid arteries in about 80%. In 1 patient cerebral angiography revealed a giant aneurysm which was erroneously considered as a suprasellar neoplasm at CT and encephalography. The demonstration of the supraclinoid arteries was often inadequate in large suprasellar tumors. Cerebral angiography is still necessary preoperatively in suprasellar pituitary lesions.sbd.at least at the state of technology represented by the Delta 25 Head Scanner.
