Bromocriptine-Treated Giant Lactating Adenoma: A Case Report with Imaging Findings

ABSTRACT

Lactating adenoma is a benign breast disease that occurs during pregnancy or lactational periods. Here we report on a case of rapidly enlarging lactating adenoma in a 28-year-old postpartum woman, which was mistaken for a malignant breast tumor. Treatment with bromocriptine resulted in a rapid reduction of the mass, suggesting that bromocriptine could be used for shrinking lactating adenoma and to facilitate surgical removal. We describe its imaging findings, including ultrasonographic findings with correlative histologic features, confirmed by surgical excision.
