Scrotal gray-scale and color Doppler sonographic findings in genitourinary Brucellosis

PURPOSE: Brucellosis is an enzootic disease that is frequently transmitted from Brucella-infected animals and their products to humans through the gastrointestinal tract. Genitourinary complications are seen in 2-10% of cases. We used sonography to investigate such complications in patients from a Brucella-endemic area. METHODS: Between 1992 and 1996, 246 patients were clinically and serologically diagnosed as having brucellosis and were examined by sonography. RESULTS: Genitourinary complications were identified by sonography in 26 patients. Fifteen of these patients had unilateral epididymo-orchitis, 6 had diffuse orchitis, and 5 had a focal hypoechoic testicular lesion. An increase in the vascularity of the lesions was seen in the 14 patients who also underwent color Doppler examination. Spectral waveform analysis showed a decrease in the resistance index in 9 patients. After medical treatment, all but 1 of the lesions disappeared within 2 months; the last lesion persisted for 6 months. CONCLUSIONS: In areas in which brucellosis is endemic, when scrotal abnormalities are seen with gray-scale or color Doppler sonography, the possibility of genitourinary tract complications of brucellosis should be considered. Simple Brucella tests may prevent unnecessary surgery.
