“…There are several causes of diffuse bladder wall calcification. Globally, the most common cause of bladder calcification is Schistosomiasis, which results from migration of Schistosomiasis haematobium from the heart (after penetration of the skin and circulation through the venous system) to the venous plexus surrounding the bladder [34][35][36]. Bladder wall calcification is observed in many patients infected with S. haemato-bium.…”

The authors present 14 cases from the film interpretation session of the 11th annual meeting of the European Society of Urogenital Radiology presented in September, 2004. The cases demonstrate the imaging findings, differential diagnoses, and clinical relevance of a wide variety of genitourinary tract diseases. The cases include examples of benign and malignant urinary tract neoplasms, inflammatory processes, vascular diseases, traumatic injuries, and congenital anomalies.

“…Calcification of the SVs caused by schistosomiasis is well known, but only 1 case of schistosomiasis granuloma appearing on CT as a solid mass in the SVs has been reported. 23 Our series included 4 cases in which schistosomiasis granulomas appeared as SV masses on TRUS; 3 of them were bilateral and the fourth, unilateral. Calcifications were present in all our patients with schistosomiasis, appearing as diffuse, scattered bright echoes in 3 cases and as a rim-like calcification in 1 case.…”

“…A shell-like rim of calcification, an appearance produced by the submucosal deposition of eggs and not caused by fibrosis, has little to no effect on bladder capacity or emptying. Later in the course of infection, when the bladder wall becomes fibrotic and the bladder contracts, leading to a reduction in capacity, marked changes become visible at cystography (37,(45)(46)(47).…”

Genitourinary schistosomiasis is produced by Schistosoma haematobium, a species of fluke that is endemic to Africa and the Middle East, and causes substantial morbidity and mortality in those regions. It also may be seen elsewhere, as a result of travel or immigration. S haematobium, one of the five fluke species that account for most human cases of schistosomiasis, is the only species that infects the genitourinary system, where it may lead to a wide spectrum of clinical symptoms and signs. In the early stages, it primarily involves the bladder and ureters; later, the kidneys and genital organs are involved. It rarely infects the colon or lungs. A definitive diagnosis of genitourinary schistosomiasis is based on findings of parasite ova at microscopic urinalysis. Clinical manifestations and radiologic imaging features also may be suggestive of the disease, even at an early stage: Hematuria, dysuria, and hemospermia, early clinical signs of an established S haematobium infection, appear within 3 months after infection. At imaging, fine ureteral calcifications that appear as a line or parallel lines on abdominopelvic radiographs and as a circular pattern on axial images from computed tomography (CT) are considered pathognomonic of early-stage schistosomiasis. Ureteritis, pyelitis, and cystitis cystica, conditions that are characterized by air bubble-like filling defects representing ova deposited in the ureter, kidney, and bladder, respectively, may be seen at intravenous urography, intravenous ureteropyelography, and CT urography. Coarse calcification, fibrosis, and strictures are signs of chronic or late-stage schistosomiasis. Such changes may be especially severe in the bladder, creating a predisposition to squamous cell carcinoma. Genital involvement, which occurs more often in men than in women, predominantly affects the prostate and seminal vesicles.
