A 36-year-old man presented to the emergency room with a 3-week history of intermittent, intense epigastric pain. He had an episode of alcoholic pancreatitis 8 months before, which was complicated by a 9-cm pseudocyst located in the body and tail of the pancreas. The patient did not attend the follow-up appointment. He denied having fever, vomiting, weight loss, or gastrointestinal hemorrhage, and claimed to be abstemious. Physical examination was normal, except for epigastric tenderness. Blood tests including hemogram, amylase, lipase, and inflammatory markers were unremarkable. Computed tomography (CT) scan showed that the pseudocyst remained stable in size and contained a small amount of high-attenuation debris ([Fig. 1]); there were signs of left portal hypertension determined by compression of the splenic vein. Endoscopic ultrasound (EUS) revealed a vessel within the cyst, evidence of intracystic hemorrhage, and hemosuccus pancreaticus ([Fig. 2]). The patient remained hemodynamically stable but his hemoglobin level dropped by 1.5 g/dL. No pseudoaneurysm or contrast extravasation was detected on abdominal angiography. Emergent surgery was proposed, but the patient refused further intervention and was discharged on request. A few weeks later, the patient returned to the emergency room due to abdominal pain. CT demonstrated a vessel within the cystic wall ([Fig. 3]). The patient underwent surgery with ligation of the vessel and drainage of the cyst; he remains asymptomatic at 6-month follow-up.
Hemorrhage is a rare but potentially lethal complication of pancreatic pseudocysts, and is the result of erosion of the adjacent vessels by compression and proteolytic action of the cystic contents [1]. A high index of suspicion is needed as bleeding is usually intermittent. In our patient, EUS was essential for ensuring appropriate diagnosis. Evaluation of pancreatic pseudocysts with EUS prior to drainage provides a highly detailed view of the pseudocyst and surrounding structures, which may result in significant changes to the management plan [2] [3].
