Testicular calcification and microlithiasis: association with primary intra-testicular malignancy in 3,477 patients.

The prevalence of all forms of scrotal and testicular calcification and their association with testicular tumour in a symptomatic paediatric and adult population was investigated. A retrospective study of all testicular ultrasound examinations performed at a single centre over a 5-year period was undertaken. All studies were performed by experienced operators, recorded in a standard method, using high-frequency linear array transducers (> or =10 MHz).
