title: Computed tomography in the evaluation of the supraclinoid arteries in suprasellar pituitary gland tumors.
abstract: The demonstration of the supraclinoid arteries at CT in 38 patients with suprasellar lesions was evaluated. The anterior cerebral artery was visible in 8 per cent, the other supraclinoid arteries in about 80 per cent. In one 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. Therefore, cerebral angiography is still necessary preoperatively in suprasellar pituitary lesions-at least at the state of technology represented by the Delta 25 Head Scanner.
