[Scrotal calcification associated with hydrocele testis in a child: a case report].

Scrotal calcification is a rare complication of childhood hydrocele testis. Herein, a 12-year-old boy who suffered from left hydrocele testis with intrascrotal calcification is reported. The boy had experienced scrotal pain about 6 months prior to the first visit to our hospital, and gradually noted scrotal swelling. Physical examination revealed left scrotal enlargement with transillumination. Sonographic examination revealed a left hydrocele testis, and a 1.5 cm discrete focus of calcification was found immediate cranio-lateral to the left testis, contour, size and consistency of which were palpated normally. In left hydrocelectomy, no appendix epididymidis was found. A smooth, white, spherical, firm body connecting to the head of the epididymidis was removed. A microscopic examination revealed multiple layers of collagenous tissue with the necrotic tissue in the core. We concluded that this case presented with hydrocele testis secondary to a growing calcification reacting to the infarction due to the repeated torsion of the appendix epididymidis.
