Cavernous hemangioma accounts for 5% to 12% of all spinal vascular anomalies [1] and mainly occur in the vertebral body. Therefore, intradural extramedullary cavernous hemangioma are rare compared with vertebral body, epidural, and intramedullary cavernous hemangioma [2], with hemorrhagic transformation being very rare. Hemorrhagic transformation exacerbates the patient's neurological symptoms. In our case, the patient had a sudden neurological deterioration. Here, we report a case of hemorrhagic transformation of cavernous hemangioma presenting with sudden paraplegia, and have added the pertinent literature review.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
