Sonographically Detected Testicular Microlithiasis / 대한비뇨기과학회지

ABSTRACT

Testicular microlithiasis (TM) is an uncommon abnormality in which concentric laminated bodies are scattered throughout the testis within seminiferous tubules. The sonographic appearance of TM is characteristic. In a retrospective analysis of 281 testicular sonograms, TM were found in 7 cases (2.5%). The presence of TM was associated with the presence of acute epididymitis (n=3), varicocele (n =l), hydrocele (n =l), testicular tumor (n =l), and cryptorchidism (n =l). The pathogenesis of TM is still poorly understood and its clinical relevance is unclear. However, because TM may be associated with testicular tumor, we advocate careful evaluation and follow up of the testes when this abnormality is detected.
