RESUMEN

INTRODUCTION: Pons herniation after cabergoline therapy for giant prolactinoma is a complication not documented in literature. CASE REPORT: We report a medium aged patient who developed secondary hemiparesis after 18 months of medical treatment. MRI revealed pons herniation into the clivus. There was improvement with conservative treatment. Secuencial MRIs are presented showing the tumor at the moment of the diagnosis, tumor shrinkage and pons herniation. DISCUSSION: Some studies have shown that a significant and rapid tumor shrinkage resulting from treatment with cabergoline can occur and it is thought that some complications are related with this tumor regression, as in the presented case.
