Sonographically detected testicular microlithiasis and testicular carcinoma

Abstract
Testicular microlithiasis is an uncommon abnormality that produces the characteristic sonographic appearance of diffuse, punctate, hyperechoic foci throughout the testicular parenchyma. We have detected this distinctive sonographic pattern in 4 patients during a seven-year period. Three of the patients had proven concurrent testicular carcinoma. We describe our experience and review previous reports of testicular microlithiasis. We conclude that testicular microlithiasis may be associated with testicular neoplasia, and advocate particularly careful evaluation and followup of the testes when this abnormality is detected. © 1993 John Wiley & Sons, Inc.
