A 58-year-old Indian man presented with one-month history of dull pain and mass in the left upper quadrant of abdomen. There was no history of fever or weight loss. Clinical examination revealed splenomegaly. Hemoglobin, renal and liver function tests were within normal limits. Abdominal computed tomography (CT) revealed a 5×6 cm nonenhancing heterogeneous cystic lesion in pancreatic tail infiltrating the spleen. A provisional diagnosis of pancreatic cystic neoplasm was made and the patient was referred for endoscopic ultrasonography (EUS).
