title: Ectopic adrenal tissue as radiographic lymphadenopathy in renal cell carcinoma.
abstract: In the presence of solid, contrast-enhancing renal mass, concomitant contrast-enhancing retroperitoneal mass is usually viewed as regional lymph node metastasis unless proven otherwise. The present report of ectopic adrenal tissue demonstrates that the presence of retroperitoneal contrast-enhancing mass may be a benign finding in patients with renal malignancy. Pathology remains the definitive method for diagnosis in such situation.
