Breast Filariasis Diagnosed by Real Time Sonographic Imaging: A Case Report

Abstract

A 30-year-old woman presented with a palpable subcutaneous nodule in the areolar region of the left breast. Sonomammographic examination revealed 2 cystic lesions showing typical “filarial dance” as vigorous twirling movement of multiple curvilinear echoes with mixed red blue color Doppler signals that was non-rhythmic, nonpulsatile, and the characteristic pulse Doppler trace due to irregular worm movement. Real time sonographic demonstration of these typical features is pathognomonic for filariasis, especially in endemic areas and treatment should be initiated without delay on the basis of ultrasound.
