Information About the Field of Cavernomas

What Is a Cavernoma?

A cavernoma refers to a benign vascular malformation consisting of an accumulation of altered veins. As a result, they can cause bleeding even at low pressure, which either goes undetected or manifests as headaches , paralysis, or seizures. Cavernomas can occur in the brain as well as in the spinal cord. They are congenital but can also develop during life.

Causes of Cavernomas

The exact cause of cerebral cavernomas is unknown. Some of the malformations are hereditary.

Symptoms and Diagnosis of Cavernomas

20-40% of cerebral cavernomas do not result in symptoms. Sometimes they are discovered incidentally in a cranial CT or MRI. Symptomatic cavernomas typically become prominent between the ages of 10 and 50. Symptoms depend on the location of the vascular malformation. They often become symptomatic with epileptic seizures or present as movement and speech disorders .

Cranial CT is carried out to clarify acute symptoms of a possible cavernoma. Bleeding can be diagnosed reliably and quickly on the CT image. Further clarification of the cause can be made by CT angiography or head MRI.

Cavernoma Therapy

Whether to treat and which therapy is best for the patient depends on numerous factors and must be decided on a case-by-case basis. An influence in this decision is symptomatology and localization of the cavernoma. Cavernomas in the cerebrum are usually more harmless in their course than those in the brainstem. Symptomatic cavernomas are removed neurosurgical if they are easily accessible. A wait-and-see approach is taken for asymptomatic cerebral cavernomas.

Cavernoma Surgery

Because cavernomas are benign alterations, they can usually be removed entirely, and patients are subsequently considered cured. Surgical therapy is recommended when cavernomas become symptomatic. The closer a cavernoma is to functionally essential areas in the brain, the earlier it causes symptoms. The proximity of the cavernoma to essential structures in the brain presents a significant challenge for neurosurgeons, so the indication for surgery must be critical, and exceptional safety measures must be taken. These measures include techniques such as neuro-navigation-assisted surgical planning, functional navigation, microscopic surgery, and intraoperative monitoring.

Cavernoma Irradiation

For cavernomas in inoperable localizations, the option of radiation is available. Neither definite indications nor necessary dose has been established for radiosurgery yet. A combination with previous neuroradiological surgery is possible. However, the closure rates are significantly lower and also occur after an average of 18 months. In a few cases, even more, extended latency periods have been described. Irradiation can be carried out equivalently with proton radiation or stereotactic radiosurgery (gamma-knife, cyber-knife, linear accelerator).

Bleeding Risk in Cavernomas

The risk of bleeding is approximately 0.25-3.1% per patient year. After bleeding, the risk for another bleeding increases to about 4.5% per patient year.

Which Physicians and Clinics Are Specialized in Cavernomas?

Close collaboration between neurosurgeons, neuroradiologists, neurologists, and radiation oncologists is important for the optimal treatment of cavernoma patients. In neurology clinics, patients are usually treated on an outpatient basis, and a diagnosis is made in collaboration with neuroradiologists. It is carried out by neurosurgeons if surgery is necessary, while radiation oncologists carry out radiation therapy.
