Diffuse cavernous hemangioma of the rectum: evaluation and MRI.
Computed tomography (CT) and magnetic resonance imaging (MRI) were used preoperatively to stage the extent of a diffuse rectal hemangioma in a 37-year-old man with recurrent rectal bleeding. On T2-weighted MR scans, the lesion demonstrated a heterogenous signal intensity with large portions displaying the hyperintensity characteristic of hemangiomas of solid organs. MRI did not depict calcified phleboliths evident on CT and barium enema.
