Neuroimaging studies of cerebral "visceral larva migrans" syndrome.

"Visceral larva migrans" syndrome is a zoonotic disease caused by the migration or presence in human tissue of nematode larva from lower-order animals. This syndrome includes generalized illness, eosinophilia, and symptoms arising from larval invasions of different organs including the liver, lungs, eyes, and central nervous system. There has been only one case report of the computed tomographic (CT) and magnetic resonance imaging (MRI) appearances of cerebral toxocaral disease. Described here is a patient with cerebral toxocaral disease with a high eosinophil count and toxocaral titer in the serum and abnormal CT and MRI findings who had spontaneous recovery of the clinical symptoms.
