Abstract

Pituitary apoplexy is a rare and severe complication of pituitary adenoma that may present with new-onset headache, ocular palsy, visual disturbances, life-threatening electrolyte imbalance, and endocrinological disturbances due to pituitary hemorrhage and/or infarction.

We report the case of a 58-year-old previously healthy patient who developed isolated mild oculomotor nerve palsy of the left eye following osteosynthesis of a traumatic right distal radius fracture. Initial cerebral magnetic resonance imaging showed a pituitary macroadenoma without characteristic signs of pituitary infarction or hemorrhage. The patient presented to the neurology department on the fifth postoperative day with malaise and fatigue due to pituitary insufficiency, deteriorated rapidly and required intensive care monitoring. Clinical stabilization was achieved through the administration of hydrocortisone, and transsphenoidal resection of the pituitary lesion was performed on the 10th day after acute symptom onset. Histological examination revealed a necrotic pituitary adenoma.

Pituitary apoplexy may occur after minor surgery in patients with pituitary adenoma. Clinicians should pay particular attention to laboratory signs of pituitary insufficiency in new-onset oculomotor nerve palsy associated with sellar lesions, as cerebral imaging may miss pituitary apoplexy and therefore delay diagnosis and treatment. In our case, delayed decompressive transsphenoidal resection resulted in the normalization of the oculomotor nerve palsy while the pituitary insufficiency persisted. The potential impact of an earlier surgical intervention on the outcome of pituitary function remains uncertain.
