Spontaneous perforating hematoma of the rectum. Report of a case.

Intramural hematomas of the intestine most often occur in the setting of blunt abdominal trauma. However, spontaneous hematomas can occur secondary to either hematologic disorders, or use of anticoagulant therapy. There has been no clearly documented report of a spontaneous rectal hematoma. We describe the novel treatment of a patient with a spontaneous intramural hematoma of the rectum which presented as an abdominal catastrophe.
