Renal lymphangiectasia is a very rare disorder that results from developmental malformations affecting the renal lymphatic system. Patients of any age may present with a range of symptoms, such as abdominal pain, flank pain, a palpable mass, and hypertension. Radiologic features include lymphatic cysts forming a rind-like appearance along the outer edge of the renal cortex. We report a case of renal lymphangiectasia in a 49-year-old man presenting with headache and back pain, highlighting the characteristic imaging features and key diagnostic considerations of this rare condition.
