精巣上体炎の治療中に全般性精巣梗塞を認め精巣摘除に至った1例

Abstract

We report a case of global testicular infarction associated with epididymitis. A 26-year-old man with a history of clean intermittent self-catheterization since he was 1 year old presented to our hospital with left scrotal pain and swelling. He was diagnosed with epididymitis and was prescribed levofloxacin. On the next day, he returned with worsened symptoms of left scrotal pain, swelling, and fever. He was admitted because of his severe symptoms and high C-reactive protein level in the blood test. Antimicrobial therapy with intravenous flomoxef and analgesic treatment with pentazocine and loxoprofen were started but the symptoms did not improve. The color-Doppler ultrasound repeated on the 1st, 4th, and 5th day of admission showed left epididymal hypervascularity but it did not indicate testicular hypovascularity in any examinations. On the 6th day of admission, a contrast-magnetic resonance imaging (MRI) scan revealed no contrast enhancement in the left testis and high orchiectomy was performed. On pathological examination, abscess of the entire epididymis and generalized necrosis of the testes were observed. Inflammatory cell infiltration and thrombus formation were observed in almost all veins of the testis and spermatic cord, and the diagnosis of global testicular infarction associated with epididymitis was made. Global testicular infarction has been reported as a rare complication of epididymitis and should be considered in the case of atypical course of epididymitis.
