Renal artery aneurysms (RAAs) are rare. Diagnosis is typically incidental with most cases asymptomatic and detected on routine imaging. Rarely large saccular RAAs may appear to extend to the neighbouring renal parenchyma. Differentiating these from renal tumours can be difficult and subsequent investigation with biopsy may result in fatal rupture. Our case describes an RAA arising from the right renal artery masquerading as renal cell carcinoma (RCC). Emphasis is placed upon thorough radiological evaluation ensuring that RAA is considered and excluded from the differential diagnosis prior to biopsy or surgical intervention. The role of multidisciplinary input is also emphasised.
肾动脉动脉瘤（RAAs）较为罕见。诊断通常是偶然发现的，大多数病例无症状，在常规影像学检查中被检测到。很少有大的囊状肾动脉动脉瘤可能看起来延伸至邻近的肾实质。将这些与肾肿瘤区分开来可能很困难，随后进行活检可能导致致命的破裂。我们的病例描述了一例起源于右肾动脉的肾动脉动脉瘤，伪装成肾细胞癌（RCC）。重点在于进行全面的放射学评估，确保在活检或手术干预之前考虑到肾动脉动脉瘤并将其从鉴别诊断中排除。还强调了多学科协作的作用。
