Segmental testicular infarction: Sonographic findings and pathologic correlation
J Ultrasound Med
Segmental testicular infarction can mimic testicular carcinoma on sonography and can lead to unnecessary orchiectomy. This case series describes and correlates sonographic and histologic findings of 7 pathologically proven segmental testicular infarction cases. Segmental testicular infarction should be suspected on sonography when a geographic lesion with low or mixed echogenicity has absent or near-absent flow in a patient with scrotal pain. A hyperechoic rim and peripheral hyperemia correspond to interstitial hemorrhage and inflammatory changes. As an infarct evolves, it becomes more discrete and hypoechoic as ghost outlines replace seminiferous tubules. Follow-up or contrastenhanced magnetic resonance imaging or sonography can increase diagnostic confidence in suspected cases and prevent unnecessary orchiectomy.
