We present a case of a large pancreatic pseudocyst in a 69-year-old man following post biopsy pancreatitis. Radiological findings revealed a thick-walled, fluid filled mass in proximity to the pancreas. Although pancreatic pseudocysts generally self-resolve, extensive or complicated cysts may require surgical or interventional management. Pseudocys...
