Pancreatic Lymphangioma Mimicking Mucinous Cystadenoma: A Report of a Rare Case

Abstract

Background: Pancreatic lymphangioma (PL) is a rare benign neoplasm arising from the lymphatic system. The imaging features of PLs are valuable but not pathognomonic, distinguishing PLs from other pancreatic cystic lesions is still a great challenge.Case presentation: In our study, we present a 62-year-old woman with PL showing tumor in the distal pancreas, which was misdiagnosed as mucinous cystadenoma preoperatively. Laparoscopic cystectomy was performed after onsite assessments intraoperatively and the recovery was uneventful. Conclusions: PLs should be included in the differential diagnosis of pancreatic cystic neoplasms and a minimally invasive way for PL treatments is also of great importance. This case will be a good complement for the whole PL cohort.
