Tuberculous orchitis US and MRI findings. Correlation with histopathological findings

Tuberculosis of the testis is a rare disease. Although Ultrasound (US) findings of tuberculous epididymo-orchitis have been well described, there are only few reported cases describing the Magnetic Resonance Imaging (MR) findings of this disease. Herein, we describe the US and MR findings in a patient with tuberculous orchitis of the left testis and correlate them with the histopathological findings. In our case, the MR findings differ from previous studies because granulomatous areas in the testis had intermediate to high signal intensity on T2WI, while in all studies granulomatous areas in tuberculous epididymo-orchitis demonstrated invariably low signal intensity.
