Cavernous angiomas of the brain stem and spinal cord.
This article reviews the pathology, clinical course and management of cavernous angiomas in the brain stem and spinal cord. Both lesions have been diagnosed with increasing frequency as a result of magnetic resonance image scanning. Brain stem lesions tend to present dramatically; their treatment remains microsurgical excision despite some studies that have looked at the use of radiosurgery. Spinal lesions are either extra-, or more commonly, intramedullary. Intramedullary cavernomas present with a wide spectrum of symptoms ranging from acute haematomyelia to presentations that mimic demylelinating conditions; extramedullary cavernous angiomas tend to produce radicular symptoms or subarachnoid haemorrhage. Both are treated by microsurgical excision.
