Perirenal Macrocystic Lymphatic Malforamtion in a Neonate: A Case Report

Abstract

Perirenal lymphatic malformation (LM) is a rare benign lesion that often simulate as perinephric collection or parapelvic cyst. A neonate, antenatally diagnosed with a renal cystic mass, was investigated to have a perirenal LM on postnatal ultrasonography and MRI. The LM was excised successfully. Histopathologic examination of the specimen confirmed the diagnosis. Perirenal LM should be evoked for a renal cystic mass diagnosed prenatally. Knowledge of this entity can prevent an unnecessary nephrectomy.
