摘要

我们在此报告一例与igg4相关的肾脏疾病（IgG4-RKD）合并不典型囊性肾肿块的病例，患者为73岁男性。计算机断层扫描显示肾脏弥漫性肿大及左肾囊性肿块。血液检查显示IgG和IgG4水平升高。肾活检诊断为IgG4-RKD。根据临床、影像学和超声检查结果，认为囊性肿块是良性的。未见恶性或脓肿形成。类固醇治疗后肾功能和IgG4水平均有改善；此外，肿块缩小，提示IgG4-RKD病因。IgG4-RKD患者应考虑囊性肾肿块伴囊性形成。

An Atypical Cystic Renal Mass in a Patient with IgG4-Related Kidney Disease.

We herein report a case of IgG4-related kidney disease (IgG4-RKD) with an atypical cystic renal mass in a 73-year-old man. Computed tomography revealed diffuse renal enlargement and a cystic mass in the left kidney. Blood tests revealed elevated IgG and IgG4 levels. A renal biopsy led to the IgG4-RKD diagnosis. The cystic mass was deemed to be benign based on the clinical, imaging, and ultrasonography findings. No malignancy or abscess formation was noted. Both the renal function and IgG4 levels improved after steroid treatment; moreover, the mass shrunk, suggesting an IgG4-RKD etiology. Cystic renal masses with capsule formation should be considered in patients presenting with IgG4-RKD.
