Abstract:
Objective To study the connection between MRI characteristics of spinal cavernous hemangioma(SCH)and its clinical and pathological features.Methods 20 cases of SCH confirmed by pathology were retrospectively analysed.The characteristics of MRI signal intensity were analysed in comparison with the clinical manifestations and pathology.Results Among the 20 cases,5 lesions located in the cervical segment of spinal cord,12 lesions in the thoracic segment,2 in the lumbar segment and 1 in the thoracic-lumbar segement.SCH could be devided into four patterns:intramedullary lesion,epidural lesion,intradural-extramedulary lesion and vertebral lesion.The typical MRI characteristics of SCH were mixed signal intersity on T_1 or T_2 weighted images,low signal intensity ring could be seen around the lesions and more pronounced on T_2 images.Spinal cord compression syndrome was the main clinical manifestation.Cavernous hemangiomas were red or purple mulberg-like lesions which were composed of dilated,thin-walled vessel with a simple endothelial lining and a variably thin fibrous adventitia under the microscope.Conclusion MRI is the most reliable method in diagnosing SCH,MRI characteristics of signal intensity of SCH are correspond with their clinical and pathological features.
