Arterio-portal fistula may develop at the biopsy site after percutaneous liver biopsy and demonstrates a characteristic appearance on angiography and Lipiodol computed tomography scan of the liver performed shortly after the biopsy. Radiologists should be familiar with these findings in order to avoid misinterpretation of arterio-portal fistula as hepatoma in hepatitis B carriers. (J HK Coll Radiol 2001;4:294-296)
