Intrathoracic kidney is very rare and has the lowest prevalence among all renal ectopias. We report the case of a 70-year-old male who was referred for diethylenetriaminepentaacetic acid (DTPA) scan as a part of presurgical work-up for a right renal mass. PriorUltrasonography abdomen incorrectly reported left kidney as normal in location. Tc-DTPA renal scan combined with single-photon emission computed tomography - computed tomography revealed impaired global glomerular filtration rate with left kidney in ectopic (intrathoracic) location. 18-fluorodeoxyglucose positron emission tomography-computed tomography images revealed a soft tissue mass completely replacing the right kidney with metastases to bilateral lungs. This case reemphasizes the importance of nuclear medicine imaging in diagnosis and evaluation of the renal function of the intrathoracic kidney.
胸内肾非常罕见，在所有肾异位中患病率最低。我们报告了一例70岁男性患者，该患者因右肾肿物行术前检查，接受二乙三胺五乙酸（DTPA）扫描。之前的腹部超声检查错误地报告左肾位置正常。锝-二乙三胺五乙酸肾扫描联合单光子发射计算机断层扫描-计算机断层扫描显示，左肾异位（胸内），整体肾小球滤过率受损。18-氟脱氧葡萄糖正电子发射断层扫描-计算机断层扫描图像显示，一个软组织肿块完全取代了右肾，并转移至双侧肺。该病例再次强调了核医学成像在胸内肾诊断和肾功能评估中的重要性。
