The 'hot' hepatic abscess

A case of hepatic abscess appearing as a 'hot' lesion on the radiocolloid scintigraph is presented. Local stimulation of reticuloendothelial elements is suggested as the probable explanation for this unusual finding. Focal liver lesions demonstrating increased radiocolloid uptake have been described over the past few years in association with hemangioma and various venous obstructions. In this report an abscess is documented as another lesion producing a focal increase in hepatic radiocolloid concentration.
