On ln-111 WBC images, diffuse homogeneous uptake of the radiopharmaceutical should be present throughout the liver. The authors present a case of a febrile patient with polycystic liver disease in whom the normal diffuse uptake was not seen. Instead, the images demonstrated focal areas of uptake, which suggested infection. Tc- 99m SC liver spleen scintigraphy demonstrated the In- 111 WBC foci to correspond to areas of residual normal parenchyma. The patient underwent laparotomy and liver transplantation and no abscesses were found. Pathologic examination of the liver revealed multiple uninfected cysts and residual normal parenchyma in the caudate lobe, corresponding to the findings on scintigraphy.
