PITUITARY APOPLEXY INTO NONADENOMATOUS TISSUE - CASE-REPORT AND REVIEW

Pituitary apoplexy into nonadenomatous tissue is extremely rare, The authors describe a 20-year-old woman with symptomatic pituitary hemorrhage into an apparently intrasellar malignant teratoma, which caused headache, visual impairment, involvement of III, IV, VI, and 1st division of the V cranial nerves, and hypopituitarism, Diabetes insipidus had developed previously. Magnetic resonance scans had a high-intensity signal in the pituitary on T1- and T2-weighted images, and lack of the signal of the posterior pituitary, Transsphenoidal approach, radiotherapy, and chemotherapy management did not preclude a fatal outcome.
