| Summary: | Introduction. Pituitary apoplexy (PA) is a rare and potentially life-threatening clinical syndrome resulting from pituitary gland hemorrhage and/or infarction. Anticoagulation is a risk factor for triggering PA. Isolated oculomotor nerve palsy is an atypical presentation of PA. Case Presentation. A 65-year-old African American female with no past medical history of pituitary disease presented to the emergency department (ED) with nonspecific abdominal pain that was thought to be secondary to fecal stasis and subsequently improved with laxatives. She also reported atypical chest pain that was concerning for unstable angina. She was started on aspirin, clopidogrel, and intravenous (IV) heparin. Later, coronary catheterization showed no significant coronary artery disease (CAD). Twelve hours after the procedure, the patient developed acute complete left oculomotor nerve palsy with a severe headache. Magnetic resonance imaging (MRI) of the head showed a large pituitary mass. Pituitary apoplexy was suspected and the patient eventually underwent a successful trans-sphenoidal pituitary resection. Discussion. We report a case of PA manifesting as isolated left oculomotor nerve palsy without visual field defects in the setting of using dual antiplatelet therapy (DAPT) and IV heparin for acute coronary syndrome. To the best of our knowledge, this unique combination has not been previously reported. |
