Additional File 1:

Transverse scan of the patient's right iliac crest. A large onchocercoma with a small cystic area (echo-free – black – zone) can be seen. Within this cystic area movements of the adult filaria(e) are visible. Fragments of the worm body can be seen as a double layer membrane. The corresponding image can be seen as figure 2B.

Additional File 2:

Longitudinal scan of the patient's right trochanter. A homogenous medium sized onchocercoma can be seen. Although there is no cystic – echo-free area, worm movements are presented in the b-mode image (arrow). Lateral shadows and a back wall reflection are visible. The corresponding image can be seen as figure 3A.

Additional File 3:

Transverse scan of the patient's left knee. A large cystic onchocercoma can be seen. Movements of a conglomerate of coiled adult filariae are displayed in the cystic fluid of the nodule. Static fragments of the worms are visible in the lower left part of the video image. The corresponding image can be seen as figure 4A.
