Beautiful aspect of hydatid cyst

Abstract

Hydatid Disease (HD) is a mild endemic disease caused by ecchinococus granulosus. It can affect any system of the body, with hepatic predilection [1,2]. Most often asymptomatic, the literature describes 5 evolutionary stages ranging from simple cysts, with it poses a problem of differential diagnosis in its simple form to complicated forms that may or may not be calcified. It is made up of three sofas; the pericyst, ectocyst, and endocyst. The CT scan plays an important role in imaging complicated hydatid cysts. The most common are rupture and superinfection. Occurring in 50 to 90% of cases, the rupture can be communicative or contained. When contained, the endocyst detaches from the pericyst appearing as a curvilinear structure or floating membranes which may subsequently calcify. This aspect is found on ultrasound, or on a CT scan [1,3]. The case on this hepatic ultrasound (Figure 1A) generated a grossly oval lesion, containing calcified serpiginous structures (floating membranes), generating shadow cones which mask the posterior reinforcement of this non-vascularized fluid mass on color Doppler (yellow star).
