A case of alveolar hydatid disease of the liver for which progression was seen on CT images

Abstract

A 59-year-old woman with autoimmune hepatitis was referred to our hospital for examination of a liver tumor detected in 2001. A CT scan showed a hypovascular mass, and a liver biopsy revealed the presence of an inflammatory pseudotumor. A June 2003 CT scan showed enlargement of the tumor and polycystic pathological changes. Echinococcus antibody was positive, and a diagnosis of liver hydatid disease was made. A liver left lobe resection was performed. CT was useful in this case for detecting change in the lesion and for making the diagnosis of liver hydatid disease.
