Rare presentation of May-Thurner syndrome in childhood with lower abdominal ectopic kidney.

We report a case of a child who presented clinically with features of nephrotic syndrome and May-Thurner syndrome consecutively in the first decade of life. Initially, the nephrotic syndrome was diagnosed and treated. May-Thurner syndrome was suspected clinically in later childhood when there was remission of nephrotic syndrome with persistent left lower leg swelling. The specific imaging modalities are used to document the mechanical compression of the left common iliac vein by the lower abdominal ectopic left kidney before definite management. Our discussion highlights the role of various imaging modalities in the diagnosis of May-Thurner syndrome.
