MR features of a case of chronic expanding hematoma.
We describe a patient with chronic expanding hematoma that was pathologically confirmed by examination of the resected specimen. It has increased gradually in the right lower lung field during a period of 10 years without symptoms. The MR T2-weighted image was useful to establish a diagnosis of chronic expanding hematoma, because of the mosaic of various signal intensities we named the "mosaic sign".
