The pancreatic pseudocyst is a collection of pancreatic fluid surrounded by a non-epithelialized wall comprising granulation tissue and fibrosis, occurring in approximately 10% of patients diagnosed with acute pancreatitis and in 20–38% of those with chronic pancreatitis. Most pseudocysts are situated in the pancreatic head and pancreatic body, but about 20% develop in extrapancreatic locations. We present the case of a 46-year-old male patient diagnosed with chronic alcohol pancreatitis with acute exacerbation, who developed a large pancreatic pseudocyst with subcapsular location in the right hepatic lobe; this was successfully treated by laparoscopic surgical drainage, with no postoperative complications and no recurrence of the pseudocyst. The computed tomography scan and postoperative biochemical analysis of the intracystic fluid played a key role in establishing the diagnosis of this rare condition. An intrahepatic pancreatic pseudocyst is a rare location for pancreatic pseudocysts, but one located in the right hepatic lobe is extremely rare. The treatment of intrahepatic pancreatic pseudocysts may be conservative, though endoscopic, percutaneous, or surgical drainage may be necessary. The presence of symptoms, signs of extrinsic compression, or complications require drainage of the pseudocyst. The “take-away” lesson learned from this case: surgical treatment for pancreatic pseudocysts located subcapsularly in the liver may be considered when they are very large, or when minimally invasive treatment has not been effective.
