Abstract
A 32-year-old male patient with prolactin-producing pituitary adenoma was treated with 10 mg/day of bromocriptine (CB-154). The pre-administration baseline value of prolactin was 5, 000 ng/ml, which markedly decreased to 2-3 ng/ml after treatment. Computed tomography and pneumoencephlography performed at the time CB-154 administration was started showed the presence of a large supra and right parasellar extension of this tumor. About one year after the start of CB-154 treatment, the tumor had completely disappeared on CT scans. It is thought that CB-154 treatment reduced the size of a large prolactin-producing pituitary adenoma in this case.
