A case of hepatic hydatid disease and imaging findings

A 45-year-old female patient was admitted to our hospital due to a space-occupying lesion which was found in a physical examination. Slight tenderness was found in her right lower abdomen for 1 month. On computed tomography (CT) imaging, a round, low-density lesion was observed in the liver. Several round cysts with lower density and thin wall were scattered in the center of the lesion. Linear calcification could be found in partial cystic wall. No significant enhancement was found in the lesion on contrast-enhanced CT imaging. A laparotomy was performed to remove the mass, which was sent to a pathological examination and hepatic cystic echinococcosis was diagnosed.
