Intrathoracic kidney is a partial or complete displacement of the kidney above the hemidiaphragm into the mediastinal compartment of the thorax. It is usually seen as an incidental finding discovered on chest radiograph or abdominal ultrasound. However computed tomography consents the correct detection of intrathoracic masses and defines their shape, size, and extent. We here report a case of ectopic thoracic kidney in a 22-year-old man who had a long history of scrotal discomfort associated with right varicocele. Frequently, this ectopia does not affect renal function and the stretched ureter provides good drainage. In literature, a small number of cases shows that varicocele is a possible mode of presentation of kidney tumors, but this is the first case of varicocele secondary to intrathoracic kidney ectopia.
胸腔内肾是指肾脏部分或全部移位至横膈上方进入胸腔的纵隔腔。它通常是在胸部X光片或腹部超声检查时偶然发现的。然而，计算机断层扫描有助于正确检测胸腔内肿块并确定其形状、大小和范围。我们在此报告一例22岁男性的异位胸腔内肾病例，该患者长期存在与右侧精索静脉曲张相关的阴囊不适。通常，这种异位情况不会影响肾功能，且拉长的输尿管可提供良好的引流。在文献中，少数病例表明精索静脉曲张可能是肾肿瘤的一种表现形式，但这是首例继发于胸腔内肾异位的精索静脉曲张病例。
