Available treatment for DHG will vary depending on the location in the brain that the tumor arises, but typically the first stage of treatment is surgical resection, with the aim of removing as much of the tumor as possible (i.e. gross- or near-total resection). Concomitantly, patients will undergo radiotherapy or proton therapy.
A vestibular schwannoma (VS), also called acoustic neuroma, is a benign tumor that develops on the vestibulocochlear nerve that passes from the inner ear to the brain. The tumor originates when Schwann cells that form the insulating myelin sheath on the nerve malfunction.
