Abstract
IntroductionDesmoplastic fibroma is an extremely rare primary benign bone tumor. It occurs most often in the mandible, followed by the femur and pelvis. To the best of our knowledge, fewer than 200 cases have been described in the published literature. Furthermore, this case is the first report of desmoplastic fibroma with simultaneous presentation in two different locations.Case presentationWe present an unusual case of desmoplastic fibroma in a 56-year-old Caucasian man, who presented to our hospital with lumbar pain. Computed tomography and magnetic resonance imaging were performed, demonstrating two lytic expansile lesions affecting both his left iliac bone and his left sacral wing. Curettage and cortical-cancellous grafting was performed, followed by postoperative computed tomography and magnetic resonance imaging.ConclusionDesmoplastic fibroma with unusual and simultaneous manifestations in two different locations has never been reported previously to the best of our knowledge. The purpose of this case report is to present the computed tomography and magnetic resonance imaging features of this rare tumor before and after the surgical treatment. Furthermore, the radiological findings with the description of the characteristics and the clinical presentation of this rare tumor, contribute to the wide spectrum of manifestations of this tumor, in order to recognize it and to have the appropriate management.

Desmoplastic fibroma (DF) of bone is a rare, lytic, locally aggressive but non-metastatic tumor that was first described by Jaffe in 1958 [1]
Summary
DF of the bone is a rare benign tumor with clinical symptoms that are usually non-specific. It is a benign tumor that should be included in the differential diagnosis list of any lytic bone lesion, especially in young patients. It differs from other benign fibrous lesions in that the lesion is very destructive locally and often recurs after incomplete excision.
