There is a 5.8 x 4 x 5.1 cm subhepatic mass centred upon the duodenum which appears to be intramural and of intermediate density (40 HU). This appears to mildly displace the adjacent head of pancreas and superior mesenteric vein and mildly compress the underlying inferior vena cava. Small locules of intramural gas is seen in duodenal wall medial to the mass. No adjacent fat stranding.The remainder of the bowels are unremarkable. The liver, pancreas, spleen, gallbladder, kidneys and adrenals are normal. No evidence of pneumoperitoneum. Small amount of pelvic fluid is physiological. The imaged lung bases are clear. No suspicious osseous lesions.
Conclusion: Intramural duodenal mass likely reflects a haematoma in this context. Correlation with the gastroscopy findings is suggested.
