Filariasis is a prevalent parasitic infection of lymphatic frequently seen in tropical countries. It has been reported in cytological samples from various sites; however, presence of microfilaria in smears from the urine sample is an uncommon finding. We describe an interesting and unusual case of elderly female who presented with achylous hematuria and an exophytic mass lesion in urinary bladder on computed tomography scan suspected of neoplastic mass lesion; however diagnosed as urinary filariasis on urine cytology and bladder biopsy.
