Testicular germ cell tumors are the most common malignancies in men. Testicular torsion is also a scrotal phenomenon seen in adolescence and adulthood. The co-occurrence of these two scrotal disorders is extremely rare.
A 28-year-old East Asian man presented at our hospital with painless bilateral scrotal swelling. Both scrotal ultrasonography and computed tomography findings showed bilateral testicular tumors, and magnetic resonance imaging demonstrated a lack of enhancement in his right testis, indicating a hemorrhagic infarction and a left testicular tumor. After a bilateral orchiectomy, the intraoperative and histopathological findings revealed a left seminoma with a complicating contralateral testicular torsion that had developed with hemorrhagic infarction.
Testicular germ cell tumor with contralateral torsion is extremely rare. We could differentiate this case from bilateral testicular tumors appropriately using magnetic resonance imaging, and suggest that magnetic resonance imaging examination may be necessary to diagnose bilateral testicular masses.
睾丸生殖细胞肿瘤是男性最常见的恶性肿瘤。睾丸扭转也是在青少年和成年期出现的一种阴囊病症。这两种阴囊疾病同时发生极为罕见。
一名28岁的东亚男性因双侧阴囊无痛性肿胀前来我院就诊。阴囊超声和计算机断层扫描结果均显示双侧睾丸肿瘤，磁共振成像显示其右侧睾丸无强化，提示出血性梗死以及左侧睾丸肿瘤。双侧睾丸切除术后，术中及组织病理学检查结果显示为左侧精原细胞瘤，并伴有对侧睾丸扭转并发出血性梗死。
伴有对侧扭转的睾丸生殖细胞肿瘤极为罕见。我们通过磁共振成像能够将该病例与双侧睾丸肿瘤进行恰当区分，并建议磁共振成像检查对于诊断双侧睾丸肿块可能是必要的。
