title: Pupillary sparing oculomotor palsy from metastatic carcinoma.
abstract: A 60-year-old male with adenocarcinoma of the rectum had the acute onset of complete oculomotor palsy with pupillary sparing. Computed tomography scan and sellar tomograms demonstrated an ipsilateral parasellar mass with bony destruction. This case illustrates the need for a thorough search for metastatic disease in patients with third nerve palsy and known carcinoma.
