title: Human toxocariasis. Review with report of a probable case.
abstract: A 23-year-old woman with fever, myalgias, stridor, pelvic cramping, lower abdominal pain, and profound eosinophilia was presumed to have toxocariasis. An enzyme-linked immunosorbent assay titer of 1:64 and an elevated IgE level supported the diagnosis. The patient became asymptomatic without treatment, and the eosinophil count returned to normal over several months. A stool sample from her dog was found to contain Toxocara canis ova, but the patient had no history of geophagia. Presumably, she acquired infection by hand-to-mouth transmission of infectious ova after handling the dog. Toxocariasis from this type of transmission is usually not seen in an adult, but it does occur, as this case demonstrates. Thus, the primary care physician should consider toxocariasis in any patient with a suggestive clinical picture and eosinophilia.
