Ultrasound can be used in cases of filariasis to detect the presence of the adult worms in the lymphatics. It is used also in knowing how far the medical therapy is effective. Dilated lymphatic channels and living worm moving showing what is called filarial dance sign are noticed in the ultrasound.<ref name="pmid7570894">{{cite journal| author=Dreyer G, Noroes J, Amaral F, Nen A, Medeiros Z, Coutinho A et al.| title=Direct assessment of the adulticidal efficacy of a single dose of ivermectin in bancroftian filariasis. | journal=Trans R Soc Trop Med Hyg | year= 1995 | volume= 89 | issue= 4 | pages= 441-3 | pmid=7570894 | doi= | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=7570894  }} </ref><ref name="pmid15482404">{{cite journal| author=Mand S, Debrah A, Batsa L, Adjei O, Hoerauf A| title=Reliable and frequent detection of adult Wuchereria bancrofti in Ghanaian women by ultrasonography. | journal=Trop Med Int Health | year= 2004 | volume= 9 | issue= 10 | pages= 1111-4 | pmid=15482404 | doi=10.1111/j.1365-3156.2004.01304.x | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=15482404  }} </ref>

Overview

Ultrasound can be used to detect the presence of the adult worms in the lymphatics. It is also used in estimating the effectiveness of the medical therapy. Dilated lymphatic channels and living worm movement known as the filarial dance sign, are noticed on the ultrasound.

Ultrasound

  • Ultrasound can be used to detect the presence of adult worms in lymphatic vessels. Some studies used ultrasonography to follow up effectiveness of treatment. In some cases, worms can be visualized in the breast lymphatics.[1][2]
  • On ultrasound, the following findings can be observed:
    • Dilated lymphatic channels
    • Living worms tend to be in motion which is called "filarial dance" sign
