Abstract

Liver tumors may be detected on imaging studies performed for an unrelated reason or chronic liver disease follow-up, and sometimes it is difficult to differentiate between benign and malignant. A 59-year-old woman was admitted for a growing hepatic mass. Abdomen ultrasound revealed a 3.4 cm hyperechoic and mixed echoic mass. Computer tomography revealed a liver mass with early arterial enhancement and washout on the delayed phase. The liver biopsy was done but did not diagnose exactly. She underwent surgery and her liver tumor was diagnosed as an angiomyolipoma. The angiomyolipoma may be seen as a hetero- or homogenous echogenic mass in ultrasound. We should consider an angiomyolipoma as if an echogenic mass in the liver is discovered without any risk factor.
