The MRI findings of cavernous hemangioma in the thoracic spinal epidural space / 实用放射学杂志

ABSTRACT

Objective To explore the MRI features of cavernous hemangioma in the thoracic spinal epidural space,to improve the recognition of the disease.Methods The clinical,pathological and MRI data of 7 cases with cavernous hemangioma in the thoracic spinal epidural space confirmed by surgery and pathology were analyzed retrospectively.Results 7 cases of cavernous hemangioma in the thoracic spinal epidural space were included in our study,all cases underwent MRI contrast enhancement examination and 6 of them underwent conventional MRI examination.On T1WI,4 cases showed hypointensity,2 cases showed slightly hypointensity and 1 case showed mixed slightly hypointensity.On T2WI,5 cases showed slightly hyperintensity,1 case showed slightly hypointensity. On fat suppression sequence,5 cases showed hyperintensity,1 case showed heterogeneous hyperintensity.On diffusion-weighted imaging (DWI),7 cases showed obviously hyperintensity.On contrast-enhanced images,the lesions enhanced homogeneously in 5,enhanced heterogeneously in 2.Conclusion MRI can display the location,appearance and enhancement pattern of thoracic spinal epidural cavernous hemangioma distinctly,while definite diagnosis of which still depends on pathology.
