[A case of prolactinoma associated with craniopharyngioma].
A surgical case of prolactinoma associated with craniopharyngioma is reported. A 47-year-old man was admitted to some neurosurgical clinic on October 12, 1982, because of visual disturbance, general fatigue and impotence. Laboratory study revealed hyperprolactinemia (360 ng/ml) and slight enlargement of sella turcica indicated the pituitary adenoma. Transsphenoidal surgery was performed to remove the tumor on November 20, 1982. Histopathological examination revealed chromophobe adenoma, and prolactin was stained in the tumor cells by means of immunoperoxidase staining. Though the clinical symptoms had been improved after surgery, visual disturbance became worse about one month later. At that time empty sella syndrome was suspected and the second operation (interhemispheric approach) was performed on January 21, 1983. No pathological changes were observed at all. On July 13, 1983, he was transferred to our clinic, because his visual acuity was deteriorating. At this time we reviewed the previous CT scan and noticed a suprasellar mass. It was supposed that the lesion had been overlooked and was the cause of the visual disturbance. On August 1, 1983, a bifrontal craniotomy was performed and the suprasellar tumor was removed. Pathological examination of the tumor revealed craniopharyngioma. So it was supposed that pituitary adenoma and craniopharyngioma had been coexisting since onset. Except for cases with von Recklinghausen's disease, multiple primary intracranial tumors of different cell types are relatively rare. A review of literature revealed 94 cases until 1986. The most frequent combination of multiple tumors was meningioma and glioma. But we could not find any case of pituitary adenoma associated with craniopharyngioma in the literature.(ABSTRACT TRUNCATED AT 250 WORDS)
