Bilateral perirenal lymphangiectasia is a rare condition characterized by the dilation of lymphatic ducts and the formation of fluid-filled cavities. Renal lymphangiectasia is rarely observed, affecting approximately 1% of cases, with only 34 bilateral cases reported in adults by 2025. This case report discusses a 55-year-old male with a history of recurrent pyelonephritis who was eventually diagnosed with bilateral acquired perirenal lymphangiectasia based on CT, MRI, and cytochemical analysis of perirenal fluid. The patient exhibited mild left flank pain without further complications, and given the disease's benign nature, an expectant management approach was adopted. Follow-up assessments confirmed an asymptomatic status. This report highlights the importance of considering lymphangiectasia in differential diagnoses for renal cystic lesions to avoid unnecessary procedures. Our case is the 35th documented instance of bilateral renal lymphangiectasia in the literature, underscoring the need for medical awareness of this condition to improve diagnosis and patient care.
双侧肾周淋巴管扩张症是一种罕见疾病，其特征为淋巴管扩张以及形成充满液体的腔隙。肾淋巴管扩张症很少见，约占病例的1%，截至2025年，成人双侧病例仅报告了34例。本病例报告讨论了一名55岁男性，有复发性肾盂肾炎病史，最终根据CT、MRI以及肾周液体的细胞化学分析诊断为双侧后天性肾周淋巴管扩张症。患者表现为轻度左侧腰痛，无进一步并发症，鉴于该疾病的良性性质，采取了观察等待的管理方法。随访评估证实患者无症状。本报告强调了在肾囊性病变的鉴别诊断中考虑淋巴管扩张症以避免不必要手术的重要性。我们的病例是文献中记录的第35例双侧肾淋巴管扩张症，强调了提高对该疾病的医学认识以改善诊断和患者护理的必要性。
