Cysticercosis of the nervous system: diagnosis by means of specific radioimmunoscan.

A new method for diagnosing cerebral cysticercosis by means of specific radioimmunoscan is described. The method has been evaluated in 24 patients with encouraging results. The technique involves a single intravenous injection followed by brain scanning and thus far has been entirely nontoxic. The accuracy of the scan was confirmed in 6 patients by surgical removal of lesions that coincided in location and number with the diagnostic scan of the parasites.
