A patient presents with right-sided scrotal swelling, pain, fever, and a highly vascular testis on ultrasound. The most likely diagnosis is:

In acute scrotal infection, fever with scrotal pain plus Doppler evidence of increased blood flow points to an inflammatory process rather than a twisting condition, which would have reduced flow. When both the epididymis and the testis are inflamed, the combined diagnosis is epididymo-orchitis. The description of a highly vascular testis alongside the clinical signs fits infection involving both structures, making epididymo-orchitis the most appropriate label. If only one structure were involved, the name would refer to that single site, but the scenario implies simultaneous involvement of both the epididymis and the testis.
