WebCushing reflex (also referred to as the vasopressor response, the Cushing effect, the Cushing reaction, the Cushing phenomenon, the Cushing response, or Cushing's Law) is a physiological nervous system response to increased intracranial pressure (ICP) that results in Cushing's triad of increased blood pressure, irregular breathing, and ... WebThis tumor is a locally aggressive, destructive form of astrocytoma. It spreads into, or "infiltrates"normal brain, and is considered malignant. It may occur anywhere within the central nervous system (CNS). Conventional treatment options include surgery and radiation therapy. Even after these treatments, it may recur.

WebThings to remember. An acoustic neuroma is a benign, slow-growing tumour that originates in the canal connecting the brain to the inner ear. Other names for this type of tumour include ‘vestibular schwannoma’ and ‘neurinoma’. An acoustic neuroma begins in the cells that line one of the two nerves that make up the eighth cranial nerve.
