Suture Granuloma Mimicking Renal Cell Carcinoma: Magnetic Resonance Imaging (MRI) and Pathologic Correlation

Abstract

Solid renal masses are generally distinguished with contrast enhancement and intratumoral fatty foci by radiological examinations. The present of enhancement is most important criteria for diagnosis of malignant lesions. Generally, a contrast enhanced solid mass in kidney is accepted as a neoplasm. Foreign body granuloma is an extraordinary cause of enhanced solid renal mass. This case of a renal suture granuloma demonstrated peripheral enhanced exophytic renal mass mimic renal cell carcinoma, and underwent surgery. At the solid renal mass with different radiological features, biopsy is an option to determining the necessity of surgery as well as the surgical approach.
