title: Imaging features of bilateral breast plasmacytoma as unusual initial presentation of multiple myeloma: case report and literature review.
abstract: Breast plasmacytoma (BP) is an extremely rare extramedullary manifestation of multiple myeloma (MM). We report the imaging findings of an unusual case in which BP was the initial presentation of MM. A 53-year-old woman with no contributory medical history underwent chest computed tomography to evaluate intermittent nocturnal anterior chest pain, and bilateral multiple breast masses were found. Following an ultrasound-guided core needle biopsy, these lesions were confirmed to be BP.
