title: Pseudotumor of kidney.
abstract: Hypertrophy of the renal columns of Bertin may present as a mass, at times difficult to distinguish from neoplasia or cyst. Herein, we present a case characterized by the inability of this lesion to absorb 99mTc DTPA (99mTechnetium diethylenetriaminepentaacetic acid) isotope on two separate renal studies.
