Hydatid cyst of liver ultrasound (type II: cyst with daughter cyst(s) and matrix)

Hydatid disease, caused by Echinococcus granulosus, is a parasitic disease that is endemic in many parts of the world. The radiologic findings range from purely cystic lesions to a completely solid appearance. Ultrasound is the most important imaging modality for liver hydatid disease and clearly demonstrates the floating membranes, daughter cysts, and hydatid sand characteristically seen in purely cystic lesions. There are several classification schemes for liver hydatid cysts based on their ultrasound appearances; the initial classification by Gharbi et al and the World Health Organization classification are the most commonly preferred Cyst classification Based on morphology the cyst can be classified into four different types 2: type I: simple cyst with no internal architecture type II: cyst with daughter cyst(s) and matrix type IIa: round daughter cysts at the periphery type IIb: larger, irregularly shaped daughter cysts occupying almost the entire volume of the mother cyst type IIc: oval masses with scattered calcifications and occasional daughter cysts type III: calcified cyst (dead cyst) type IV: complicated cyst, e.g. ruptured cyst
