Renal lymphatic abnormalities are rare, and the understanding of pathophysiology involving renal lymphatics is limited. Symptoms can include hypertension, hematuria, proteinuria, chyluria, and abdominal and lumbar pain. Imaging techniques specific to the renal lymphatics have not been clarified. We review the intrahospital imaging evaluation/workup and clinical course of a 6-year-old male who presented to our institution with a large perirenal cyst. His presentation presented a diagnostic and management challenge. The cyst was determined to be lymphatic in origin and required multiple interventional radiology and surgical procedures for management.

肾淋巴管异常罕见，对涉及肾淋巴管的病理生理学的了解有限。症状可能包括高血压、血尿、蛋白尿、乳糜尿以及腹痛和腰痛。肾淋巴管特有的成像技术尚未阐明。我们回顾了一名 6 岁男性的院内影像学评估/检查和临床过程，他因一个大的肾周囊肿就诊于我们机构。他的演讲提出了诊断和管理方面的挑战。确定囊肿起源于淋巴管，需要多次介入放射学和外科手术进行管理。
