[A pancreatic pseudocyst in the liver]
Summary
A liver pseudocyst, unrelated to the pancreas, was diagnosed in a 43-year-old woman. It likely arose from heterotopic pancreatic tissue, treated successfully with resection and intestinal drainage.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Embryology
Background:
- Pancreatic pseudocysts typically arise from pancreatic duct injury or inflammation.
- Hepatic cystic lesions require careful differential diagnosis.
Observation:
- A large cystic lesion in the liver of a 43-year-old woman was histologically identified as a pancreatic pseudocyst.
- The patient's native pancreas appeared normal and showed no connection to the liver cyst.
Findings:
- Histologic examination confirmed the liver cyst as a pancreatic pseudocyst.
- The pseudocyst was successfully treated via partial resection and Roux-en-Y hepaticojejunostomy.
- Post-operative imaging at 8 months showed near-complete resolution of the hepatic lesion.
Implications:
- This case suggests heterotopic pancreatic tissue as a potential, albeit rare, source of pancreatic pseudocysts.
- Embryonic malformations leading to ectopic pancreatic tissue should be considered in the differential diagnosis of unusual cystic liver lesions.
- Surgical management involving resection and enteric drainage can be effective for hepatic pseudocysts of ectopic origin.
