Bilharzial arthropathy.
The joints of 124 young adult patients with bilharziasis were examined. Heels, sacroiliac joints, cervical spine, knee joint, dorsal spine, and tarsal joints were affected. Biopsy of the knee synovia showed synovitis, vasculitis, and the presence of bilharzial ova in three cases. Radiologically the heels and sacroiliac joints showed inflammatory changes. Schistosomiasis may cause an arthropathy.
