Intramural duodenal hematoma (IDH) occurs mainly in children, secondarily to blunt abdominal injury. In adults, blunt abdominal trauma accounts for 70 % of IDH cases [1]. Nontraumatic causes of IDH in adults include coagulation disorders, duodenal biopsy, and endoscopic injection therapy for bleeding ulcers [2]. Very few cases of IDH of pancreatic origin have been reported [3] [4] [5]. We describe a case of IDH presenting as a complication of pancreatic cancer. This report highlights the need to consider a malignant process as a possible etiology of IDH.

A 70-year-old man was admitted to hospital with coffee ground emesis and epigastralgia. There was no history of alcohol use, anticoagulant therapy, nonsteroidal anti-inflammatory drug (NSAID) use, or recent abdominal trauma. On esophagogastroduodenoscopy, multiple distal esophageal ulcers and a volcanic ulcerative mass in the duodenal bulb, which had a significantly narrowed lumen, were noted (Figure [1]). Biopsy specimens of the mass consisted of duodenal mucosal tissue with ulceration that was infiltrated by inflammatory cells but not tumor cells. Abdominal computed tomography demonstrated a heterogeneous, hyperdense mass located in the right anterior pararenal space and a low-attenuation mass in the uncinate process of the pancreas (Figure [2]). A diagnosis of an intramural duodenal hematoma secondary to the pancreatic mass was made.

Figure 2 Unenhanced abdominal computed tomography scan shows a heterogeneous, hyperdense mass in the right anterior pararenal space adjacent to the duodenum (arrowheads). A low-attenuation mass is shown in the uncinate process of the pancreas (arrow).

The patient underwent a Whipple procedure. An ovoid tumor, measuring 3 × 3 × 2.8 cm, was located in the uncinate process of the pancreas (Figure [3]). The duodenum was gray, fleshy, and soft, with an 8 × 5 × 1.8 cm hemorrhagic cystic lesion within the duodenal wall, which was in contact with the margin of the pancreatic tumor (Figure [3]). On microscopy, moderately differentiated ductal adenocarcinoma of the uncinate process of the pancreas, with invasion to the duodenal submucosa, was seen. Postoperatively, the patient recovered uneventfully and was discharged after 15 days.
