Pancreatic pseudocyst that compressed the inferior vena cava and resulted in edema of the lower extremities.

To our knowledge, edema of the lower extremities has not previously been reported as a sign of a pancreatic pseudocyst. In this case report, we describe a 66-year-old man in whom such a lesion compressed the inferior vena cava and caused pronounced leg swelling. After drainage of the pseudocyst, the edema did not recur. Although the most well-known complications of pancreatic pseudocyst are pain, hemorrhage, rupture, infection, and obstruction of adjacent viscera, bilateral edema of the lower extremities can be the initial manifestation of this lesion.
