title: Bilateral renal lymphangiomatosis: sonographic findings.
abstract: Renal lymphangiomatosis is an exceedingly rare disorder characterized by developmental malformation of the lymphatic system surrounding the kidneys. We report a case of bilateral renal lymphangiomatosis in a 21-year-old man who underwent abdominal sonographic examination that revealed numerous cystic areas of various sizes around both kidneys with extension along the renal hilum. Subsequent abdominal CT examination demonstrated bilateral, multilocular, fluid-filled cystic masses with thin walls in the perirenal and peripelvic region. MRI of the patient revealed bilaterally enlarged kidneys with multiple hyperintense lesions in both perirenal spaces and the peripelvic area on T2-weighted images. These cystic spaces appeared hypointense on T1-weighted images with no enhancement in postcontrast images. The diagnosis of renal lymphangiomatosis was made based on typical imaging findings.
