The symptoms of dizziness, nausea, vomiting, and tinnitus may be caused by central diseases, vestibular diseases, intracranial tumors, and intracranial occupations. Most of them are caused by infarcts in the cerebellum, but when they affect the vestibular artery of the patient, the vestibular artery becomes occluded and the symptoms of nausea, vomiting and tinnitus will occur. Secondly, if the dizziness, nausea, vomiting, and tinnitus are not accompanied by ataxia, and if the patient walks without limb immobility, the possibility of Ménière’s disease should be considered. Thirdly, if the patient has a chronic onset and the patient’s condition gradually progresses, it should be considered to be caused by a tumor in the pontocerebellar horn region, which can be clarified by CT or MRI examination of the head.
