A rare case of very large extrarenal pelvis: A diagnostic dilemma

Abstract

Extrarenal pelvis is considered to be an anatomical variant. It is seen as a cystic mass just outside the renal sinus. It can be confused with parapelvic cyst, hydronephrosis or other renal masses. Over the years, computed tomographic (CT) urography has evolved as the primary imaging modality for evaluating the urinary tract in various clinical settings and to diagnose pathologies like congenital abnormalities, filling defects, dilatation, narrowing etc.
