Radioisotope Photoscanning of the Liver in Bilharzial Hepatic Fibrosis

Cairo, Egypt

ABSTRACT

Radioisotope photoscanning of the liver was done in 51 subjects: 12 normals and 39 patients suffering from hepatosplenic bilharziasis, using colloidal gold tagged with gold-198.

In normal individuals the borders of the liver scan were well-defined and regular, the distribution of radioactivity was homogenous, and the spleen was not visualized.

In the early bilharzial cases the hepatic shadow in the scan was more commonly enlarged than not, though retaining its regular defined borders. In 28% of these early cases significant mottling was apparent, whereas the spleen was visualized in 33% of them. In the late group of cases, the main abnormal findings were the irregular ill-defined borders, an abnormal liver size, and unequal distribution of radioactivity with variable grades of reduced density and mottling. The spleen was seen in 57% of these late cases.

Therefore, photoscanning can be used as an aid for the proper assessment of the degree of liver damage in bilharzial patients.
