Atypical fat necrosis of the breast: The 'mycetoma' appearance
A very unusual appearance of fat necrosis in the breast is described. The low density/hypo-echoic rim and high density/hyperechoic central part are shown on mammography and ultrasound, respectively. The mass had the appearance of a 'mycetoma' in a cavity in the lung. The radiological diagnosis of fat necrosis was confirmed by histopathology.
