Abstract

Benign multicystic mesothelioma is a rare mesothelial lesion that forms multicystic masses in the upper abdomen, pelvis, and retroperitoneum. Most cases have a benign course. We present the ultrasound and MR findings of benign multicystic mesothelioma in the left round ligament, which caused a left inguinal hernia in a 46-year-old woman.

Keywords: Mesothelioma, Cystic, Inguinal Hernia, Peritoneum

Figures and Tables

Fig. 1

A. Ultrasonography of left inguinal area shows a well defined 6×5 cm sized multiseptated cystic mass. The content of the cystic mass is anechoic without solid portion.

B. T2 weighted axial image shows a septated cystic mass on left inguinal area (black arrow). Within the cystic mass, multiple thin septae are seen without fluid-fluid level.
C. Gd-DTPA enhanced T1weighted MR image shows well enhanced cystic wall and septae, but enhancing solid portion is not depicted (black arrow).
D. In operation field, we checks the round ligament on medial aspect of inguinal ligament (black arrow), and then find a cystic mass abutting the round ligament.
E. Surgical specimen shows a gray brown mass with multiple variable sized cystic spaces, measuring 6.0×3.5×2.0 cm in size.
F. Histologic specimen (H & E stain, ×40) shows multiple cystic spaces lined by flat mesothelial cells (black arrows), and on the immunohistochemical stain, the lining cells are positive in calretinin and D2-40 and negative in CD31, which indicated mesothelial origin.
