A case of eosinophilic meningo-encephalitis accompanied by eosinophilic inflammation of the myenteric plexus in Hodgkin's disease.

A case of Hodgkin's disease with eosinophilia in the cerebrospinal fluid without blood eosinophilia is presented. An additional remarkable feature was the finding of eosinophilia in Auerbach's myenteric plexus. Cerebrospinal fluid eosinophilia is usually associated with blood eosinophilia and this is often caused by helminthic infections of the CNS. The finding of cerebrospinal fluid eosinophilia without blood eosinophilia in any patient with Hodgkin's disease should point the physician to the possibility of a localization of tumour in the CNS.
