Extensive calcification of the urinary bladder and proximal ureter wall, with marked tortuous hydroureters and hydronephyrosis, more at the left.
Bilateral perinephric fat stranding and moderate ascites are also present.
The differential diagnosis for urinary bladder calcification include infections such as tuberculosis and schistosomiasis, secondary to therapy such as radiation cystitis and cyclophosphamide toxicity and urinary bladder malignancy (urothelial carcinoma and urachal carcinoma).
Biopsy of the urinary bladder proved this to be schistosomiasis.
