Rare cystic liver lesions: A diagnostic and managing challenge

Figure 1 Ultrasound image. A: Showing an anechoic mass in the liver (light blue arrow), with a rather thin capsule (cystadenoma); B: Showing two echinococcal cysts. The first on the right (red arrow-right image) appears as an anechoic mass with hydatid sand (type CE1) (white arrow-right image), while in the second (on the left), the detached and folded endocyst membrane is obvious (type CE3) (white arrow-left image).
