Abstract
The diagnosis, surgical treatment and outcome of seven patients with histologically verified intramedullary cavernous haemangiomas are reported. Five males and two females, with progressive myelopathy were observed. The patients were aged between 7 and 61 years. The duration of their symptoms and signs before diagnosis varied from one month to 5 years. Magnetic resonance (MR) imaging was performed in all patients and spinal angiography was performed in five. All the patients underwent microsurgical resection of the cavernous haemangiomas. MR imaging diagnosed cavernous haemangiomas in all seven patients. T1-weighted images with or without contrast enhancement best defined the margins and size of the lesions. They also illustrated the exophytic components and the change in spinal cord surface well, and were important to surgical planning. T2-weighted images may be suboptimal due to their magnetic susceptibility artifacts. In all lesions, total removal was achieved. Postoperative neurological function improved in all patients in long term follow-up. With the advantages of MR examinations and more understanding about the pathological characteristics of intramedullary cavernous haemangiomas, total removal of the mass lesion should be attempted and the outcome is generally good.
