S. Morgello et al., CENTRAL-NERVOUS-SYSTEM STRONGYLOIDES-STERCORALIS IN ACQUIRED-IMMUNODEFICIENCY-SYNDROME - A REPORT OF 2 CASES AND REVIEW OF THE LITERATURE, Acta Neuropathologica, 86(3), 1993, pp. 285-288
Hyperinfection with Strongyloides stercoralis is rare in acquired immu
nodeficiency syndrome (AIDS), despite endemicity in areas where infect
ion with human immunodeficiency virus is highly prevalent. We autopsie
d two patients with AIDS and disseminated Strongyloides and describe t
heir central nervous system findings. The microscopic patterns of brai
n infection were dissimilar in the two patients, and reflected histolo
gy in systemic viscera. In one patient, a granulomatous response accom
panied filariform larvae in all locations, including granulomatous epe
ndymitis in brain. Additionally in the brain, larvae without tissue re
action were seen. In the second patient, the absence of tissue respons
e to larvae was body wide, and isolated parasites were found in centru
m semiovale. The occurrence of these patients in a region where Strong
yloides is not endemic suggests that this infection may be more preval
ent in AIDS than formerly suspected.
