A Case of Pancreatic Duct Leak Presenting as Lower Extremity Pain and Edema.

Pancreatic pseudocyst from pancreatic duct leak is one of the common complications of both acute and chronic pancreatitis. The presentation of such leaks can range from patients being completely asymptomatic to septic shock. Extra-abdominal collections of fluid due to pancreatic duct leaks are very rare. We describe a diagnostically challenging patient with acute chronic pancreatitis presenting with lower extremity swelling and pain, who was found to have a pancreatic fluid leak into the right iliopsoas, right gluteal, and thigh muscle compartment. Despite endoscopic stenting of the pancreatic duct and multiple percutaneous drain placement and antibiotic treatment for abscess formation, the patient's condition deteriorated clinically. Surgical options could not be pursued due to poor functional status.
