Abstract

The aim of this article is to make radiologists and clinicians familial with the spectrum of cystic lesions in the abdomen. Mesenteric and omental cystic lesions are uncommon. One should be familiar with them as well as with other conditions that manifest as cysts. Initial step in diagnosing a cystic abdominal mass is to localize the organ of origin. Differential diagnosis includes enteric duplication cyst, enteric cyst, mesothelial cyst, non pancreatic pseudocyst, cystic mesothelioma, cystic teratoma, and urachal cyst. There is significant overlap in imaging features of abdominal cysts, which often require histological correlation to establish a final diagnosis. The main role of imaging is to document the nature of the abdominal mass and its origin.

Highlights

Hydatid disease is caused by the echinococcus tapeworm, and can result in cyst formation anywhere in the body
We present a diagnosed case of mesenteric hydatid cyst with radiologic finding, peroperative specimen and correlated with histopathologic findings
The hydatid cysts have three layers- a) outer pericyst is formed by the host cells as a fibrous protective zone, b) the middle laminated membrane, which is acellular and allows the passage of nutrients, and c) the endocyst, where the scolices (Figure 4A) and the germinal layer are produced.[2,3]

Summary

Introduction

Hydatid disease is caused by the echinococcus tapeworm, and can result in cyst formation anywhere in the body. There are two main species of the echinococcus a) echinococcus granulosus and b) echinococcus multilocularis.[1,2] It is endemic in some areas of the world. Liver and lungs are most commonly involved organs. Mesenteric hydatid cyst is an uncommon location. We present a diagnosed case of mesenteric hydatid cyst with radiologic finding, peroperative specimen and correlated with histopathologic findings
