Testicular tuberculosis (TB) is an uncommon presentation of extrapulmonary TB. Although rare in incidence, it is a great masquerader and should be kept in consideration while assessing focal abnormalities involving the testis. Ultrasound findings alone may be non-specific and mimic other diagnoses including infection, inflammation, tumor, infarct, and trauma. The main objective of this sonographic pictorial review is to discuss the imaging findings, specific differentiating features against each differential and use of ancillary imaging findings whenever available. Concurrent involvement of epididymis, septated hydrocele, scrotal wall edema, and calcification of tunica vaginalis provides strong evidence in an appropriate setting. Available extratesticular ancillary imaging findings must be correlated for correct diagnosis due to non-specific imaging and clinical presentation. Misdiagnosis of scrotal TB may lead to otherwise avoidable epididymo-orchiectomy.
睾丸结核是肺外结核的一种不常见表现。尽管发病率较低，但它极具伪装性，在评估睾丸局灶性异常时应予以考虑。仅超声检查结果可能不具有特异性，可模仿其他诊断，包括感染、炎症、肿瘤、梗死和创伤。本超声影像学综述的主要目的是讨论影像学表现、与每种鉴别诊断的特定鉴别特征以及在可行时辅助影像学检查结果的应用。在适当的情况下，附睾同时受累、分隔性鞘膜积液、阴囊壁水肿和鞘膜钙化可提供有力证据。由于影像学和临床表现不具特异性，必须结合可用的睾丸外辅助影像学检查结果以做出正确诊断。阴囊结核的误诊可能导致原本可避免的附睾 - 睾丸切除术。
