A 39-year-old man presented with left scrotal pain which lasted for 3 days. The laboratory test showed slightly elevated C-reactive protein and lactate dehydrogenase whereas α-fetoprotein and β-human chorionic gonadotropin were normal. Scrotal Doppler ultrasound test demonstrated an oval-shaped hypoechoic lesion and enhanced magnetic resonance imaging revealed an avascular lesion in the left testis with the rim enhancement. He underwent left high orchiectomy. The histopathological examination revealed segmental testicular infarction with partial necrosis.
