Features of testicular epidermoid cysts on contrast-enhanced sonography and real-time tissue elastography.
A series of 7 testicular epidermoid cysts were imaged by contrast-enhanced sonography to assess internal vascularity and by real-time tissue elastography to grade stiffness by a visual and strain ratio quantification scoring system. No internal vascular enhancement was seen on contrast-enhanced sonography; the 3 largest lesions showed rim enhancement. On the real-time elastographic color display, all lesions were predominantly blue ("hard"), and the lesions analyzed for the strain ratio had a mean value of 43.57. Contrast-enhanced sonography depicts the absence of vascular flow, and real-time elastography shows that the epidermoid cysts are hard. This combination of information will help further characterize these lesions.
