  • Title: Caroli's disease versus polycystic hepatic disease. Differential diagnosis with Tc-99m DISIDA scintigraphy.
    Author: Pinós T, Xiol X, Herranz R, Figueras C, Catalá I.
    Journal: Clin Nucl Med; 1993 Aug; 18(8):664-7. PubMed ID: 8403697.
    Abstract:
    Four patients with multiple hepatic cysts were studied: two were diagnosed with Caroli's disease (CD) and two with polycystic hepatic disease (PHD). In CD, hepatic scintigraphy with Tc-99m DISIDA showed areas of focally increased radiotracer accumulation that persisted more than 120 minutes, whereas in PHD, areas of focally decreased radiotracer accumulation were observed with normal liver washout and biliary excretion. When multiple hepatic cysts are shown by abdominal echography or CT scan, hepatic scintigraphy with Tc-99m DISIDA should be performed. This examination is safe and noninvasive, and permits differential diagnosis between CD and PHD.
