Abstract
We retrospectively reviewed five pathologically proven cases of diffuse cavernous hemangioma of the rectosigmoid colon to define the MR imaging features of this entity. Diffuse cavernous hemangioma of the rectosigmoid colon is revealed as rectosigmoid wall thickening with high signal intensity on T2-weighted MR images. Such wall thickening is associated with abnormal perirectal fat. The extent of bowel involvement and extrarectal locations are well shown on T2-weighted MR images.
