Case Report: Filaria or Megasperm? A Cause of an Ultrasonographic "Filarial Dance Sign"

J Brad Wiggers et al. Am J Trop Med Hyg. 2018 Jul.

Abstract

Bancroftian filariasis can cause genital abnormalities related to chronic inflammation and obstruction of the afferent lymphatic vessels, and may demonstrate a "filarial dance sign" on scrotal ultrasound with mobile echogenic particles observed. We present a patient with a positive "filarial dance sign," travel within Latin America, and negative filarial serology.
