Abstract

BackgroundMucinous cystic neoplasm of the Liver is rare tumors with malignant potential that occur in the biliary epithelium. Because of its rare presentation, it is often misdiagnosed before surgery.Case presentationA 63-year-old female patient presented with intermittent upper abdominal pain for three months. Laparoscopic hepatectomy of Segment 7 was conducted based on the preoperative diagnosis of space-occupying lesion in the right lobe of the liver. Postoperative pathology showed a low-grade mucinous cystic neoplasm in the right posterior lobe of the liver. The preoperative CA19-9 level was significantly increased while the postoperative CA19-9 returned to the normal range.ConclusionsThe diagnosis of mucinous cystic neoplasm of the liver is closely related to the thickening of the cystic wall or the increase of CA19-9, which has great significance and deserves clinical attention.

Summary

Introduction

Mucinous cystic neoplasm of the Liver is rare tumors with malignant potential that occur in the biliary epithelium. Background Mucinous cystic neoplasm (MCN) of the liver was officially proposed in the fourth edition of the World Health Organization’s (WHO’s) new classification of digestive system tumors in 2010 [1], which was originally called biliary cystadenoma or cystadenocarcinoma [2]. Contrast-enhanced magnetic resonance imaging of the liver and gallbladder (Fig. 1B, C) revealed a normal size and shape of the liver and proportion of each lobe, and the intrahepatic and extrahepatic bile ducts and flow vessels ran naturally.
