Cavernomas are circumscribed lesion with thick packed, thin-walled vascular cavities. Most cavernomas are very small. They have a tendency for repeated minor bleedings.

A clinically significant bleeding occurs in about one out of five patients. The risk of bleeding is estimated to be 0.5 to 1 percent. This risk is increased according to the literature, if the cavernoma has previously bled.  The symptoms depend on the location of the cavernoma and can be epileptic seizures or neurological deficits such as paralysis or numbness.

The only treatment modality for cavernomas is surgical removal of the lesion. Especially in deep-seated cavernomas an accurate preoperative planning using magnetic resonance imaging (MRI) is necessary. Our department is also equipped with all necessary modern technical tools such as a surgical microscope, intraoperative ultrasound, neuronavigation and intraoperative neuromonitoring in order to make the operation as safe as possible in critical regions.
