摘      要：BACKGROUND Fibrous dysplasia(FD)is a common benign intramedullary fibro-osseous *** of the spine is rare,with the literature including only case reports,and cases of monostotic FD(MFD)in the sacrum are extremely rare.A correct preoperative diagnosis of spinal MFD is important for clinicians to select proper *** SUMMARY We retrospectively assessed a case report of MFD in the *** patient was examined by computed tomography(CT)and magnetic resonance imaging(MRI),and the diagnosis was confirmed by pathology.A review of the literature was performed to analyze the imaging characteristics and differential diagnoses of spinal *** our patient,the CT scan showed the lesion to be expansile,with ground glass opacity and a sclerotic *** MRI,the lesion showed iso-low signal intensity on T1WI and iso-high signal intensity on T2WI.A low signal rim was found on T1WI and *** patient was treated by posterior focal excision,decompression,bone grafting,fusion and pedicle screw fixation.A satisfactory result was achieved,with pain *** complications had occurred at the 1-year follow *** MFD is an expansile osteolytic *** glass opacity and a sclerotic margin are obvious *** lesion often involves the vertebral body and posterior *** of these imaging characteristics of spinal FD could be helpful for diagnosis and prevent unnecessary procedures.
