Cabergoline treatment in a case of macroprolactinoma after delivery

We present a case of microprolactinoma (3 mm) grown into macroprolactinoma (21 mm) during pregnancy. This patient was admitted in our hospital for left hemianopsia 13 days after delivery. Through Magnetic Resonance Imaging (MRI) a macroprolactinoma (21 mm in diameter) was diagnosed. The Prolactin (PRL) serum levels were 152 ng/ml. The patient started Cabergoline treatment with good results: normalization of PRL levels after 5 days, of the visual field after 58 days and complete disappearance of prolactinoma within 180 days from the beginning of treatment.
