Inflammatory Pseudotumor (Myoblastic Tumor) of the Genitourinary Tract

Abstract

OBJECTIVE. The purpose of this article is to describe imaging features of the following genitourinary tract locations that can involve inflammatory pseudotumor: kidney, adrenal gland, retroperitoneum or pelvis, bladder, and other rare locations. CONCLUSION. Although definite radiologic differentiation from malignancy is not clearly possible, we suggest that familiarity with the manifestations of inflammatory pseudotumor can help avoid unnecessary radical surgery before histopathologic proof of malignancy is obtained.
