Grenzen der differentialdiagnostischen Aussagefähigkeit von CT und Sonographie bei der zystischen Leberechinokokkose

In regions of only sporadic occurrence of hydatid disease, the heterogenic appearance of the cysts often causes a diagnostic dilemma. In 28 patients the reports of sonography and/or computed tomography, without and during bolus injection of 100ml anionic contrast material, were compared to the results of the indirect haemagglutination test (IHA). In six cases additionally the enzyme-linked immunosorbent assay (ELISA), and in nine the histologic specimen were evaluated. The authors discuss the value of CT and US reporting on their experience and the difficulties in establishing the diagnosis in 14 histologically and/or serologically proven cases and another 14 cases with "typical" appearance but negative serology and/or histology.
