title: False-positive radiocolloid liver image due to a subphrenic abscess.
abstract: A false-positive radiocolloid liver image can occur in various disease processes from extrinsic structures adjacent to the liver. A patient whose radiocolloid liver imaging showed an apparent photopenic area in the liver is presented; the abdominal CT demonstrated a low-density lesion located anterior to the liver, and at surgery the lesion was confirmed to be a right anterior subphrenic abscess.
