title: [A fatal course of Nelson syndrome].
abstract: An unusually therapy-resistant form of Nelson's syndrome developed in a 23-year-old woman two years after treatment of a pituitary-dependent Cushing's syndrome by bilateral adrenalectomy (1977). Removal of a corticotrophic adenoma by a first transsphenoidal pituitary operation (1979) brought only temporary relief. Two years later, regrowth and apoplexy of the pituitary adenoma led to oculomotor paralysis and had to be treated by a second transsphenoidal operation (1981). A second relapse became manifest two years later. Treatment with bromocriptine relieved the headaches but did not diminish the tumor size. A third pituitary operation (1984) became necessary when neurological signs revealed penetration of the cavernous sinus. The tumor was only partly removed by transsphenoidal surgery. Postoperative deterioration of the patient required emergency craniotomy to check a subarachnoidal hemorrhage and for removal of the remaining tumor. The patient died three days later of pneumococcal meningitis which had developed after the third pituitary operation.
