RÉSUMÉ
【Objective】 To report a case of testicular infarction due to polyarteritis nodosa (PAN), and to discuss its clinical diagnosis and treatment based on relevant literatures at home and abroad, so as to have a better understanding of this rare disease. 【Methods】 Clinical data of a case complaining of scrotal pain who was initially diagnosed as testicular torsion and later confirmed to be testicular infarction due to PAN were retrospectively analyzed, and relevant literatures were reviewed. 【Results】 With glucocorticoid, vasodilator and antioxidant treatment, the patient’s testicular blood flow was improved. 【Conclusion】 Testicular infarction due to PAN is a rare disease which is difficult to diagnose timely. The diagnosis depends on biopsy and the standards formulated by American College of Rheumatology (ACR). Good prognosis can be achieved with timely diagnosis and correct treatment.
RÉSUMÉ
Testicular torsion is a common differential diagnosis of acute scrotal pain along with acute epididymo-orchitis, which may lead to testicular non-viability. Doppler ultrasound and testicular scintigraphy are two routinely used modalities for the assessment of testicular viability. However, in some cases, these investigations may prove inadequate in differentiating between the two entities with widely differing management. Here, we present a case of a 52-year-old male with questionable viability of testis, who was investigated initially using testicular scintigraphy and was further subjected to a regional 18F-FDG PET/CT scan, in view of inconclusive findings with the conventional modalities.

A 77-year-old male underwent open repair for a right indirect inguinal hernia and complained of right scrotal pain on the third postoperative day. Color Doppler imaging revealed decreased blood flow with heterogeneous hypoechogenicity in the right testis. A Tc-99m pertechnetate testicular scan showed diffuse hyperemia and increased uptake in the right scrotum. Additional SPECT/CT revealed a photon defect in the right testicle with increased uptake in the peri-testicular area. A subsequent operation revealed a large hematoma in the right spermatic cord and consequent right testicular infarction, and right orchiectomy was performed.
