Supportive management resolved a colonic intramural hematoma in an anticoagulant user.

Intramural hematomas of the colon are rare. Intramural hematomas of the gastrointestinal tract often result from blunt trauma, although they may also occur spontaneously in patients taking anticoagulants or those with blood dyscrasia. Affected patients present with abdominal pain and lower gastrointestinal bleeding, as well as occasional signs of intestinal obstruction. The diagnosis is made using colonoscopy and abdominal CT. Resection of the involved bowel segment is accepted as the standard therapy; however, experience with conservative treatment has also been reported. We herein report the case of a 62-year-old woman taking warfarin who was diagnosed with a colonic intramural hematoma and completely recovered with conservative management.
