Primary pancreatic echinococcosis: A rare mimicking of choledochal cyst

Abstract

A 32-year-old female presented with epigastric pain, post-prandial fullness, nausea and weight loss for 6 months. Examination revealed mild pallor. Her hemoglobin was 11 gm%, absolute eosinophil count was elevated, but LFTs were normal. Abdominal ultrasound abdomen showed a prominent common bile duct (CBD), a mildly dilated main pancreatic duct (MPD), and a 5.5 × 5.3 cm cystic lesion in the head of the pancreas compressing the portal vein (PV). CT of the abdomen showed a thin-walled hypodense lesion (4.8 × 4.1 × 4.7 cm) in the head of pancreas with dilated MPD and compression of PV and proximal duodenum (Fig. 1A).
