Strongyloidiasis is a chronic parasitic infection caused by Strongyloides stercoralis, an endemic and frequent cause of pulmonary diseases in tropical and subtropical areas. It is estimated to affect over 600 million people worldwide. This roundworm is endemic in regions with suboptimal sanitation. Autochthonous transmission, in which larvae generated in the host reinfect the host, results in chronic asymptomatic infection, often with eosinophilia.Infection with human immunodeficiency virus (HIV), human T-lymphotropic virus 1 (HTLV-1), hypogammaglobulinemia, alcoholism, and malnutrition has been associated with an increased risk of strongyloidiasis.Larvae can be found in soil and penetrate the skin of people who go barefoot. After penetration, filariform larvae migrate to the lungs, where they mature, are coughed up, and swallowed. Once in the small intestine, the larvae mature into adult females, which intermittently produce eggs through asexual reproduction. These eggs hatch into rhabditiform larvae, which are excreted in the stool. The rhabditiform larvae, which are non-infectious, then give rise to infectious filariform larvae, either in the soil or within the host’s intestine. This leads to the unique phenomenon of autoinfection, where filariform larvae generated in the host invade the intestinal mucosa or perianal skin, restarting the infectious cycle.Strongyloidiasis can be chronic, acute, or lead to hyperinfection syndrome. In the latter two, patients may present with extra-intestinal manifestations, with the lungs being the most commonly affected organ.Although some reports discuss the radiological findings of strongyloidiasis, there is limited published data, to our knowledge, that describes the pulmonary manifestations of this disease on chest CT.
