Dengue hemorrhagic fever presenting with hemorrhagic pancreatitis and an intramural hematoma of the duodenal wall: a case report and review of the literature.

Dengue fever may present with atypical manifestations. Here we report a 47 year-old male presenting with fever and sore throat for 2 days, followed by epigastric pain and tarry stool for 4 days. The esophagogastroduodenoscopy revealed multiple ulcers with a nodular margin in the duodenal bulb and second portion of the duodenum. A MRI of the abdomen revealed hemorrhagic pancreatitis, with a large intramural hematoma in the second portion of duodenum. The final diagnosis was dengue hemorrhagic fever, grade II, complicated with hemorrhagic pancreatitis and an intramural hematoma of the duodenal wall. Physicians should be aware of the atypical abdominal presentations of dengue fever.
