Cavernous Malformations of the Brain (Cavernomas) - Surgical Treatment
A cavernoma or cavernous malformation is a
vascular abnormality of the central nervous system. It consists of a
cluster of abnormal, dilated veins that have the propensity to bleed.
When located in a critical area of the brain, bleeding from such a
lesion can cause neurological damage. Cavernomas located in the
brainstem have the highest likelihood of harming a patient. When they
are surgically accessible, the option of having their cavernoma
removed is given to our patients.
Case of a 60 Year old woman with progressive left-sided paralysis due to a brainstem cavernoma (red arrows on pre-operative MRI scans). She was unfortunately previously diagnosed as having had a tumor, and had received radiotherapy at another institution. At present, radiotherapy is not known to cure these lesions.
