title: Epithelial cyst arising in an intrapancreatic accessory spleen: a diagnostic dilemma.
abstract: An epithelial cyst in an intrapancreatic accessory spleen (ECIAS) is a rare disease that is commonly misdiagnosed preoperatively. To identify the clinical and imaging features of ECIAS, we reviewed the relevant medical literature. Twenty-one cases of ECIAS were identified, including our own. The cases were mainly diagnosed as mucinous cystic neoplasm (MCN) preoperatively based on clinical and imaging features, such as, a woman in middle age; elevation of serum CA19-9 levels; location in the tail of the pancreas; and a solid component resembling a mural nodule. ECIAS is another lesion to be considered in the differential diagnosis of MCN.
