Abstract

Chronic expanding hematoma is rare and occasionally misdiagnosed as malignant neoplasm. We describe a case in the female pelvis and correlate findings from pathology and magnetic resonance imaging. On diffusion-weighted images (DWI), our patient's hematoma showed 2 different signal intensities, which corresponded to pathological features of fresh and altered blood components. DWI can distinguish between such pathological features of a chronic expanding hematoma.
