[Lesions of the choroid plexus in schistosomiasis mansoni].
The histopathological study of the choroid plexus in cases of schistosomiasis showed that besides the formation of granulomatous lesions around the eggs, there is deposition of granular or linear Azan positive material in subepithelial areas. There is a suggestion that this material may represent immune complex deposit, as has been shown in the renal glomeruli in this disease.
