Indium 111 labeled white blood cell scintigraphy for the diagnosis of upper abdominal abscesses in a child with Wiscott-Aldrich syndrome.

We report on a case of multiple hepatic abscesses in an immunodeficient patient where initial radiologic evaluation by ultrasonography and computed tomography confused early management by failing to demonstrate the abscesses and by suggesting other diagnoses. Indium 111 (In-111) white blood cell (WBC) scanning with Tc-99 liver-spleen scan subtraction accurately demonstrated subcapsular hepatic abscesses in four out of four sequential studies, and later confirmed resolution of the abscesses. We suggest that In-111 WBC scanning may be used as a highly specific method of diagnosing suspected upper abdominal abscesses in children.
