| Abstract: | Objective To investigate the characteristics of magnetic resonance image(MRI) of spinal cord cavernous hemangioma. Methods Six cases of spinal cord cavernous heman-gioma diagnosed by MRI and confirmed by pathology were reviewed. The characteristics of MRI wereanalgzed and correlated with pathological characteristics of spinal cord cavernous hemangioma. ResultsIn 4 cases, the tumors were located in thoracic segment of the spinal cord and 2 in cervical cord. Alllesions were solitary and the spinal cords were normal or a little thicker. The MRI showed that the im-ages of focus were ball-like popcorn or mulberry with mixed signal,with short T2 signal around the fo-cus. Under microscope, the hemangioma was composed of highly expanded blood sinusoids and its wallwas thin and consisted of flat epithelial cells. T'here were some red blood cells in the cavity of the sinu-soid and a little fibrous tissue in the diazoma between blood sinusoids. And also some fresh and old hem-orrhages could be seen in the specimen. Conclusion MRI has high sensitivity and specificity in thediagnosis of spinal cavernous hemangioma. |
