[Focal defect of perfusion and phagocytic function caused by passive liver congestion. Report of a case].
A false-positive result of a occupant lesion of the left hepatic lobe is presented in a patient with congestive heart failure (CHF) and subacute bacterial endocarditis (SABE). Both, static liver scintigraphy and dynamic radioangiography showed a focal defect on the upper region of the left lobe, which disappeared with the CHF. It was concluded that this focal defect was caused by passive congestion of the liver. A scintigraphic sign to differentiate congestive splenomegaly to that caused and SABE is described.
