Differential diagnosis between paravertebral spinal hemangioma and neurilemmoma using MRI / 实用放射学杂志

ABSTRACT

Objective To diagnose correctly for paravertebral spinal hemangioma and neurilemmoma through retrospective analysis of characteristics of MRI.Methods Paravertebral spinal hemangiomas (n＝11)and neurilemmomas (n＝17)confirmed by surgery and pathology were analyzed retrospectively.Results Paravertebral spinal hemangiomas occurred in the thoracic epidural,hyperintense singal on T2 WI,obvious homogeneous enhancement,associated with vertebral body destruction and vertebral hemangioma.Paravertebral neurilemmomas were located in the middle and upper cervical segments and the thoracic epidural space.The solid area showed mild hyperintense singal on T2 WI,irregularly higher hyperintense signal inside,and obvious heterogeneous enhancement,without the cystic area being enhanced.The differences between the two tumors were significant in location,vertebral hemangioma,lesions of the same layer of bone destruction,relationship with the spinal cord,T2 WI signal,and enhanced performance (P＜0.05 ).There were no significant differences in age,sex,clinical manifestation,shape,volume,affected attachment,and T1 WI signal (P＞0.05 ).Conclusion The MRI findings of paravertebral spinal hemangioma and neurilemmoma are significantly different in the location,vertebral hemangioma,bone destruction,relationship with the spinal cord,T2 WI signal and enhanced performance.
