Only dizziness without headache cannot indicate whether the patient has tumor in the brain. There are many reasons for the patient’s dizziness, such as because of elevated blood pressure, which will cause the patient to have headache, dizziness and head swelling. In case of poor sleep, patients may experience dizziness, loss of muscle strength and concentration. Insufficient blood supply to the brain may also cause patients to have dizziness symptoms. There are also peripheral vertigo diseases, such as Meniere’s disease, vestibular neuronitis, and benign paroxysmal positional vertigo, all of which can cause patients to experience varying degrees of dizziness. There are also cardiac diseases, such as frequent premature ventricular beats, atrial fibrillation, chronic cardiac insufficiency, which cause dizziness in patients with cardiogenic cerebral insufficiency when the heart pumping is affected, and anemia and hypotensive conditions can cause dizziness in patients. Therefore, dizziness without headache is not necessarily a manifestation of brain tumor. Patients with tumors in the pontocerebellar horn region may suffer from dizziness, headache, and hearing loss.
