Diagnostic considerations in urinary bladder wall calcification.

Area of Science:

• Radiology
• Urology
• Pathology

Background:

• Urinary bladder wall calcification is an uncommon radiographic finding.
• Several distinct conditions can lead to calcification of the bladder wall.

Purpose of the Study:

• To present a series of patients with bladder wall calcification.
• To discuss the various etiologies of bladder wall calcification.
• To outline diagnostic approaches for bladder wall calcification.

Main Methods:

• Retrospective review of 19 patients with radiographically visible bladder wall calcification.
• Analysis of clinical history, physical examination, laboratory studies, and radiographic findings.
• Discussion of reported causes and comparison with the patient series.

Main Results:

• The series included patients with schistosomiasis (8), primary bladder carcinoma (6), encrustation cystitis (2), amyloidosis (1), cyclophosphamide-induced cystitis (1), and tuberculosis (1).
• Radiographic appearance alone is often insufficient for definitive diagnosis.
• A comprehensive diagnostic approach is necessary.

Conclusions:

• Bladder wall calcification has a limited differential diagnosis.
• Accurate diagnosis typically requires integrating clinical information, laboratory results, imaging, and cystoscopy with biopsy.
• Cystoscopy with biopsy is crucial for confirming the diagnosis and excluding malignancy.
