An Infected Intrahepatic Pancreatic Pseudocyst and Calcified Pancreas: A Rare Complication of Chronic Pancreatitis.

Pancreatic pseudocyst is a common complication of pancreatitis and is usually located in the peripancreatic space, spleen, and retroperitoneum. An infected intrahepatic pseudocyst following acute on chronic pancreatitis is extremely rare. Here, we report a case of intrahepatic pancreatic pseudocyst with superimposed infection following chronic pancreatitis in a 42-year-old female who presented with severe abdominal pain, vomiting, and bloating sensation. Her labs showed elevated pancreatic enzymes (amylase and lipase), and a provisional diagnosis of acute pancreatitis was made. Imaging revealed a cystic lesion in the left lobe and a calcified pancreas. Endoscopic aspiration of the cystic lesion and pathologic examination confirmed infected intrahepatic pancreatic pseudocyst due to the high serum amylase level and positive  on culture in aspirated cystic fluid, complicated by chronic pancreatitis.
