Schistosomiasis

An important cause of cystitis, schistosomiasis may appear as eggshell calcification in the submucosa of the bladder and ureteral wall. Chronic infection may be complicated by squamous cell carcinoma, especially when irregular filling defects or focal disruption of linear calcifications are seen.

Plain film of the pelvis shows bladder wall calcifications (open arrows) in patient with schistosomiasis infection. The right ureteral wall is also calcified (closed arrows).
