True lymphoepithelial cysts of the pancreas are rare entities which still pose a diagnostic challenge, despite the latest radiological and surgical advances. We present a case of young male who presented with an asymptomatic abdominal mass. An abdominal CT reported it as a probable solid tumour located in the body of the pancreas, whist the MR showed a cystic neoplasm. Various differential diagnoses were considered, such as papillary neoplasm, solid epithelial neoplasm, intraductal papillary mucinous neoplasm of the pancreas or mucinous cystadenoma/cystadenocarcinoma of the pancreas. However, histopathology revealed its benign, cystic lymphoepithelial nature. Close collaboration between radiologists, surgeons and pathologists is especially crucial for this lesion, since simple diagnostic procedures can prevent high risk surgery.
