ABSTRACT

Pancreatic pseudocyst is a cystic pancreatic mass filled with pancreatic enzymes, which is typically a complication of chronic pancreatitis. It is usually located at the head of pancreas or at the lesser sac of stomach and can be diagnosed with different radiology modalities such as computed tomography and endoscopic ultrasound. However, an ectopic pancreatic tissue can give rise to a heterotopic pancreatic pseudocyst and misdiagnose as other intraabdominal mass pathologies, i.e. gastrointestinal stromal tumour. We describe a case of heterotopic pancreatic pseudocyst which was diagnosed as gastrointestinal stromal tumour preoperatively based on computed tomography scan findings.

Keywords: ectopic pancreas, endoscopic ultrasound, heterotopic
