Orchitis

Orchitis is an inflammation of the testes, usually caused by an infection, such as with mumps virus or with sexually transmitted infections. People with orchitis may present with testicular enlargement, pain, tenderness, and swelling. They can also have systemic symptoms like fever, headache, and myalgias. Diagnosis is clinical, but an ultrasound must be done to rule out other causes of acute scrotum such as testicular torsion. Treatment involves symptom relief with analgesics, and antibiotics if a bacterial infection is identified.
