[Visceral larva migrans in adults with severe pulmonary manifestations].

BACKGROUND

Toxocariosis, the most frequent cause of visceral larva migrans, is usually a disease of children due to ingestion of eggs from the roundworm of dogs (Toxocara canis). Clinical expression varies from an symptomatic state to fuminant disorders; hepatomegaly with fever is frequent. Severe symptoms (rarely in adults) may occur.

CASE REPORT: A 42-year-old male with no past medical history complained of sudden onset pulmonary disorders. Laboratory findings included eosinophilia on blood tests, a severe respiratory obstructive syndrome and positive serum tests for Toxocara canis. All clinical and biological abnormalities regressed in a few weeks.

DISCUSSION: Diagnosis of visceral larva migrans is exceptional in adults and can only be proven by positive serological tests. Correct treatment remains under debate.
