OBJECTIVE: The purpose of this article is to describe the imaging features of solitary fibrous tumors involving the kidney, bladder, adrenal gland, retroperitoneum, or pelvis and other rare locations.
CONCLUSION: Although clear radiologic differentiation of solitary fibrous tumors from malignancy is not possible, we suggest that familiarity with the manifestations of solitary fibrous tumors can help to avoid unnecessary radical surgery before histopathologic proof of malignancy is obtained
