Intracranial tumors, i.e., various types of brain tumors, are one of the common diseases of the nervous system, which are very harmful to the function of the human nervous system. They are generally divided into two categories: primary and secondary. Primary intracranial tumors can occur in brain tissue, meninges, cranial nerves, pituitary gland, vascular remnants of embryonic tissues and so on. Secondary tumors refer to malignant tumors in other parts of the body that metastasize or invade the skull to form metastatic tumors. So what is brain tumor vertigo. Brain tumor vertigo can directly compress or infiltrate the vestibular nerve, vestibular nerve nucleus, cerebellar pompholytic nodule or its related nerve pathway, vertigo; or due to the intracranial pressure increase to the vestibular nerve nucleus pressure caused by vertigo. The nature of vertigo can be true or non-true, the degree is not intense, and vertigo often persists with episodic intensification. The most common brain tumor causing vertigo is acoustic neuroma, which starts with unilateral tinnitus and hearing loss, and then vertigo gradually occurs, which can be a sense of swaying and instability, rotational vertigo is less common, and later there are signs of ipsilateral trigeminal, facial nerve and cerebellar involvement. Nystagmus, ipsilateral sensorineural deafness, loss of hot and cold response can be seen on examination, and enlargement of the internal auditory canal on the diseased side or simultaneous bone destruction can be seen on cranial X-ray. Brain stem tumor is characterized by gradual appearance of one or both sides of the cross paralysis, vertigo and nystagmus may be persistent, not accompanied by hearing loss. Vertigo due to cerebellar tumors is also common, and the vertigo can take many forms, most often accompanied by cerebellar nystagmus and headache. Earthworm tumors also have significant balance disorders, with unsteadiness and frequent backward slumping. Cerebellar hemisphere tumors may be associated with ipsilateral limb hypotonia and ataxia. Patients with fourth ventricle tumors or cysts in a certain head position have acute intracranial pressure increase due to blockage of cerebrospinal fluid channels by the mass, resulting in sudden onset of vertigo, headache, and vomiting. Patients often assume a fixed head position, and positional tests may induce central positional vertigo and positional nystagmus.
