ABSTRACT
Objective To investigate the MRI features of spinal epidural angiolipomas.Methods Clinical and MRI data of 18 patients with spinal epidural angiolipomas confirmed pathologically were retrospective analyzed.The MRI features of lesion site,size,shape,signal,bone destruction,enhancement and typing were observed and analyzed.Results One case of 18 cases were located in cervical vertebra,15 cases were thoracic vertebra,and 2 cases were lumbar vertebra.Ten cases formed paravertebral lump through foramen intervertebrale and damaged adjacent bones.MRI showed that T1W1 signal intensity was either isointense (n 11),mixed intense (n=5) or hyperintense (n =2).T2WI showed signal intensity was hyperintense (n=13) or mixed intense (n=5).The fat signal was seen in 5 cases,both T1W1 and T2W1 showed hyperintense.All the 18 cases showed remarkable enhancement.Ⅰ type (lesions confined to the spinal canal) was 8 cases (8/18,44.44%),Ⅱ type (lesions were dumbbell-shaped to the spinal canal) was 10 cases (10/18,55.56%).Conclusion The location of occurrence and the manifestations of MRI in spinal epidural angiolipomas have certain characteristics,which provides important clues to the preoperative diagnosis.
