Spontaneous retroperitoneal bleeding is a rare occurrence that might have catastrophic implications. We present a 58-year-old male with a 4-day history of progressively worsening left-sided flank pain due to retroperitoneal hemorrhage from a nonfunctional renal paraganglioma. Abdominal contrast CT scan was helpful in locating the tumor, estimating tumor size and extent of bleeding, visualizing the interaction between the tumor and the surroundings, and ruling out any potential metastasis; however, it lacked specificity in identifying the origin of the mass, needing histologic investigation for a conclusive diagnosis. MRI was not available at our center. We report a rare case of spontaneous retroperitoneal bleeding as a complication of an unusual nonfunctional renal paraganglioma, which was initially misdiagnosed as renal cell carcinoma but later confirmed by postoperative histopathology.
自发性腹膜后出血是一种罕见的情况，可能会产生灾难性后果。我们报告一例58岁男性，因无功能肾副神经节瘤导致腹膜后出血，左侧胁腹痛进行性加重4天。腹部增强CT扫描有助于定位肿瘤、估计肿瘤大小和出血范围、观察肿瘤与周围组织的相互作用以及排除任何潜在转移；然而，它在确定肿块起源方面缺乏特异性，需要组织学检查以明确诊断。我们中心没有MRI设备。我们报告一例罕见的自发性腹膜后出血病例，它是一种不寻常的无功能肾副神经节瘤的并发症，最初被误诊为肾细胞癌，但后来经术后组织病理学证实。
