RESUMO
Two cases of pulmonary filariasis with atypical clinical and radiologic features without significant eosinophilia are presented. A diagnosis of pulmonary filariasis could not have been made without bronchial brush cytology, which showed sheathed microfilariae of Wuchereria bancrofti. Both cases responded well to antifilarial treatment, indicating that the microfilariae were not an incidental finding but were responsible for the symptoms and radiologic lesions.

A 26-year-old male presented with oedema, massive albuminuria and microscopic haematuria. Kidney biopsy revealed enlarged cellular glomeruli infiltrated by polymorphs and eosinophils with focal fibrin deposits along the basement membrane. Microfilariae were seen in the lumen of few glomerular capillaries. Antistreptolysin titre was negative. The absence of other aetiological factors and presence of microfilariae within glomeruli suggests that nephrotic syndrome may be due to a filarial nephritis.
