[Results of lymphography in 13 cases of onchocerciasis]

Systematic lymphographic studies in 13 cases of infection with Onchocerca volvulus have enabled a "lymphographic diagram" to be made for each infected patient. The images obtained are similar to those observed in wuchereriasis. The microfilariae in onchocerciasis, however, are not transmitted in the lymphatic system, and the lesions, which vary according to the degree of infestation, show little progression. They are found mainly in the inguino-crural ganglia which are the first main ganglionic relay system for the lower limbs.
