Discuss the treatment methods for neonatal brain cavernous angiomas, including surgery, radiation therapy, and chemotherapy, as well as the possibility of permanent cure.

A cavernous angioma is a non-solid tumor, actually a congenital cerebrovascular malformation. It contains vascular spaces, is prone to regional hemorrhaging, and gradually absorbs and softens. It primarily affects middle-aged and young adults, with hidden onset. Besides the aforementioned possible symptoms, headaches, sudden headaches after intratumoral hemorrhage, or epilepsy seizures may also occur. Head CT and MRI scans can be used for initial diagnosis.
