Mumps epididymo-orchitis: sonography and color Doppler sonographic findings
- 106 Downloads
Eleven cases of mumps epididymo-orchitis were examined by gray-scale and color Doppler ultrasonography. Nine cases were unilateral and two were bilateral. In the initial examination, the volume and the vascularity of the affected testis and epididymis and the thickness of the scrotal wall was greater than of the normal site, whereas the testicular echogenicity was decreased homogenously, resistivity indexes of intratesticular arteries were decreased, and spontaneous venous flow was seen in all cases. In contrast to nonspecific epididymo-orchitis, no hydrocele was seen, but minimal reactive hydrocele was found in two cases. The diagnosis was confirmed by specific immunglobulin-G examination. Patients were given interferon and were controlled by ultrasonography and Doppler ultrasonography at the third and seventh days of treatment and 3 months after treatment. Sonographic findings began to improve by the third day and fully disappeared in seventh day. No testicular atrophy was seen in the last control. To our knowledge, this is the first report on sonographic and color Doppler sonographic findings of mumps epididymo-orchitis.
