title: The radiographic evaluation of appendiceal calcification due to schistosomiasis.
abstract: In a 6-month period, 25 appendices with histological involvement by schistosomiasis were radiographed. Eleven showed varying degrees of radiographically detectable calcification having a spotty, linear, or amorphous pattern affecting either a short segment or the whole appendix. Four of these appendices had a mixed pattern and one also had nodular calcification in the mesoappendix. In only 1 patient was the appendiceal calcification visible on preoperative abdominal radiographs. In 5 asymptomatic patients, not submitted to surgery, appendiceal calcification was detected during radiologic evaluation of urinary schistosomiasis.
