Lymphographic abnormalities in patients with Brugia malayi filariasis and "idiopathic tropical eosinophilia".

ABSTRACT

Peripheral lymphography was carried out in 17 patients with elephantiasis and microfilaremia (Brugia malayi) and the findings compared to ten patients with "idiopathic tropical eosinophilia." There were extensive changes in peripheral lymphatic and regional nodal architecture in each group suggesting that "occult filariasis" is the cause of idiopathic tropical eosinophilia.
