Craniotomy for cavernous hemangioma epilepsy is usually curable, but if the patient’s epilepsy is also related to other factors, then seizures may still occur after surgery.
A cavernous hemangioma is a spongy abnormal blood vessel mass composed of thin-walled blood vessels. Intracranial cavernous hemangiomas can stimulate nerves, leading to abnormal nerve discharges and secondary epilepsy, which can usually be cured after craniotomy to remove the lesion that stimulates the seizures, i.e. the cavernous hemangioma.
However, if the patient’s seizures are also related to other factors, such as cortical developmental disorders, head trauma, central nervous system infections, or if the patient’s epilepsy is idiopathic in nature, then seizures may still occur after craniotomy.
If you have cavernous hemangioma or epilepsy, it is recommended that you seek medical attention and follow your doctor’s instructions.
