Makroadenom der Hypophyse mit mäßiger Hyperprolaktinämie

Abstract

This case demonstrates that the differential diagnosis of macroprolactinoma with low secretory activity and functional hyperprolactinemia is very difficult preoperatively in individual cases. This is relevant because macroprolactinomas with low secretory activity can also be treated successfully with dopamine agonists. We therefore suggest a drug treatment trial with dopamine agonists in all macroadenoms with hyperprolactinemia, particularly in those with prolactin levels above 2000 mU/l (100 ng/ml).
