Scintigraphic evaluation of the liver in Fasciola hepatica with radiocolloid and 67Ga-citrate.

A group of 23 patients with Fasciola hepatica have been studied in the province of Biscay. The diagnosis was reached after finding parasite eggs in the faeces or duodenal juice. The liver lesion was confirmed by means of macro and microscopic studies. Radiocolloid demonstrated the presence of cold areas in 18 patients; in 13 of them the uptake with 67Ga was positive. These isotopic findings identified Fasciola hepatica as one of the causes of 'cold areas' in traditional liver scans and positive 67Ga uptake.
