The most common extraintestinal manifestations of Crohn's disease involve the eyes, skin, hepatobiliary tract, and the musculoskeletal and respiratory systems. Mass-forming granulomatous inflammation in extraintestinal organs is extremely rare and there are only a few reports of patients with Crohn's disease presenting with inflammatory pseudotumours of the liver, pancreas and kidneys. We present a case of a mass-forming renal granulomatous inflammation in an adult female with Crohn's disease. The clinical, pathological and imaging features of this case illustrate that renal inflammatory pseudotumour is a rare but important differential diagnosis of a renal mass in patients with Crohn's disease and that radiologists should be aware of its existence when considering other more common pathologies, such as focal pyelonephritis and renal tumours. Renal inflammatory pseudotumour may have relatively non-specific imaging features and a biopsy may be required to make the diagnosis.
克罗恩病最常见的肠外表现累及眼睛、皮肤、肝胆系统以及肌肉骨骼和呼吸系统。肠外器官出现肿块形成性肉芽肿性炎症极为罕见，仅有少数关于克罗恩病患者出现肝脏、胰腺和肾脏炎性假瘤的报道。我们报告一例成年女性克罗恩病患者出现肿块形成性肾肉芽肿性炎症的病例。该病例的临床、病理及影像学特征表明，肾炎性假瘤是克罗恩病患者肾肿块罕见但重要的鉴别诊断，放射科医生在考虑其他更常见的病理情况（如局灶性肾盂肾炎和肾肿瘤）时应意识到其存在。肾炎性假瘤可能具有相对非特异性的影像学特征，可能需要活检来明确诊断。
