ABSTRACT


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.
