Abstract

Authoritative figures indicate that Ascaris lumbricoides has a wider geographic distribution and infests a larger number of people than any other known intestinal parasite. And since the worm in both its larval and adult stages is actively migratory, it is not surprising that disturbances resulting from the presence of the parasite in organs other than the intestine should be frequently reported. The lesions in the lungs and elsewhere caused by the larval migrations are well described in recent papers by Fülleborn,1 Stewart2 and others. The varied wanderings of the adult worm are fully considered in all textbooks on parasitology and tropical medicine (Brumpt,3 Fantham,4 Chandler,5 Castellani and Chalmers,6 and Manson7). Only a few general statements, therefore, need be recorded here, by way of introduction to the report of a case of extra-intestinal ascariasis showing certain interesting features.
