Some women with accessory glandular tissue in the axillae may present describing palpable findings with associated pain in the axillae that fluctuate with their cycles. MRI is a valuable tool for the diagnosis of accessory breast tissue, especially in peripubertal–pubertal girls and young patients. Supernumerary breast tissue may be affected by the same diseases and alterations that compromise normal breast tissue.
