Pituitary apoplexy in an acromegalic patient during bromocriptine therapy. Case report.

The authors report a case of pituitary apoplexy that developed in a patient shortly after bromocriptine therapy was started for a growth hormone-secreting pituitary adenoma. The tumor was associated with visual impairment and ocular palsies, and was treated by transsphenoidal decompression. Although spontaneous tumor necrosis cannot be excluded, a causal role of bromocriptine treatment is suggested.
