The CT findings of eleven patients with intramural hematoma of the gastrointestinal tract are presented. The most frequent site of intramural hematoma was duodenum(7/11), followed bjejunum(2/11), ascending colon(2/11), stomach(1/11), and rectum(1/11). Blunt abdominal trauma was the prime etiologic factor(7/11), others included pancreatitis, iatrogenic and unknown. Intramurla hematoma showed three patterns of CT characteristics ; intramural mass(8/11), thickened bowel wall(1/11), and both(2/11). The were variable attenuation value of 10 cases of intramural mass ; homogeneous hyperdensity or hypodensity in each 3 cases, inhomogeneous or mixed density in 4 cases. Also there were peripheral lucent halo(1/10), pseudocapsule or dense rim(5/10), crescentic hyperdensity(2/10) and central hyperdense area(4/10). Associated CT features were hemoperitoneum(4), mesenteric infiltration, fatty liver, pancreatic contusion, and chronic pancreatitis. CT is the most accurate method in establish ng the diagnosis of intramural hematoma, evaluating the extent of bleeding and its effect on adjacent organs, demonstrating regression after treatment, and detecting associated injury.
