Pituitary apoplexy, resulting from an acute infarction or hemorrhage mainly in pituitary adenomas, is a rare yet major clinical event with neurological, ophthalmological and hormonal emergent consequences. The authors review our surgical experience with a series of 16 cases of pituitary apoplexy.
The cases of pituitary apoplexy, operated via trans-sphenoidal approach in our hospital between 1998-2005, were retrospectively analyzed in terms of their clinicoradiological features, pathological findings and surgical outcomes.
The mean age of patients (9 male and 7 female) was 47.1 years. The average time of presentation after onset of symptom was 8.9 days. Pituitary apoplexy occurred as an initial manifestation of pituitary adenoma in all patients. Headache was the most common presenting symptom (94%). Visual disturbance was found in 56% of patients. Thirty-one percent of the patients had hypopituitarism. On magnetic resonance imaging, this entire catastrophic event accompanied with macroadenoma in a mean size of 22.5 mm. Only four patients needed postoperative hormone replacement therapy. Three of them showed preoperative hypopituitary function, and one patient in normal pituitary function. There was no specific complication in any of these patients.
Early trans-sphenoidal decompression with high-dose corticosteroid replacement showed good outcomes of pituitary apoplexy.
Key Words: Pituitary apoplexy; Pituitary adenoma; Transsphenoidal approach (TSA)
