[Occlusion of the intracranial segment of the carotid artery by a hypophyseal tumor].

A patient of 49 years of age presented with clinical signs of acute stroke. Computed tomography revealed a suprasellar mass and cerebral infarct. Angiographically an occlusion of the intracavernous internal carotid artery was found, caused by pituitary tumour. After total removal of the tumour the internal carotid artery was recanalised, as the postoperative angiography showed. The patient's neurological deficiencies disappeared almost completely. The literature is reviewed and our diagnosis and procedures are compared with the published reports.
