Overview
Cystic echinococcosis must be differentiated from other diseases presenting with right sided abdominal pain such as pyogenic liver abscess and amoebic liver abscess and fungal liver abscess.
Differential Diagnosis
Echinococcal cyst must be differentiated from other diseases presenting with similar features of right sided abdominal pain such as:
