Cerebral Vasospasm Following Transsphenoidal Hypophysectomy in the Treatment of Lymphocytic Hypophysitis.

Cerebral vasospasm following transsphenoidal hypophysectomy is an exceedingly rare but serious complication with high morbidity and mortality. The initial signs and symptoms of cerebral vasospasm following transsphenoidal hypophysectomy are changes in mental status, motor deficits, and speech difficulties. Symptomatic vasospasm is difficult to reverse despite treatment and often only resolves with time. Furthermore, most transsphenoidal hypophysectomy patients have been discharged before the onset of vasospasm, so when they do present it is often in a fulminant form and recalcitrant to available treatments.All previously reported patients of cerebral vasospasm following transsphenoidal hypophysectomy were status postresection of a pituitary macroadenoma. The authors report the first patient of vasospasm following transsphenoidal hypophysectomy in the treatment of lymphocytic hypophysitis; a rare inflammatory disorder characterized by lymphocytic infiltration of the pituitary gland causing destruction glandular tissue.
