A pararenal mass is a clinical finding that cannot be explored preoperatively regarding its parent organ even nowadays. We report in the following about a patient who was admitted with dull pain located in the flank and upper abdomen. Ultrasound investigation at admission showed a solid homogeneous mass close to the upper pole of the left kidney. Urinalysis and catecholamine levels were normal. Intraoperatively, a sarcoma infiltrating the renal capsule and renal vein was observed. In the case of a mass located in the area of the adrenal gland, an extra-adrenal tumor must be considered especially if there are normal findings for urinalysis and catecholamine levels even if modern imaging techniques had been applied.
肾旁肿物是一种即使在当今也无法在术前明确其起源器官的临床发现。我们在下文报告了一名因侧腹和上腹部隐痛入院的患者。入院时的超声检查显示左肾上极附近有一个实性均匀肿物。尿液分析和儿茶酚胺水平正常。术中观察到一个肉瘤浸润肾包膜和肾静脉。对于位于肾上腺区域的肿物，尤其当尿液分析和儿茶酚胺水平结果正常时，即使应用了现代成像技术，也必须考虑肾上腺外肿瘤。
