1. Headache symptoms: Patients with brain metastasis from kidney cancer often have headache symptoms, especially in the early morning, when the headache is more powerful and intense in nature, and sometimes they are also woken up in pain during sleep, but the headache will gradually ease or disappear after getting up and light activities.
2. Mental abnormalities: Mental abnormalities mainly refer to patients who often show symptoms of mental abnormalities such as melancholy, depression, forgetfulness, fiction, excitement, restlessness, etc. The reason for mental abnormalities in patients with brain metastases from kidney cancer is that brain tumors located in the frontal lobe of the brain destroy the mental activities of the frontal lobe, thus causing the above mental abnormalities.
3. Visual impairment: Because of the increased intracranial pressure, it will cause poor venous blood return to the eye, resulting in bruising and edema, which will damage the visual cells on the retina in the fundus of the eye, leading to vision loss, and vision loss is also a common manifestation of kidney cancer patients with brain metastases.
4. Vomiting: Vomiting is more common in patients with brain metastases from kidney cancer, mainly due to the increase in intracranial pressure, resulting in stimulation of the medulla oblongata respiratory center and vomiting, which occurs after a headache in the form of jets.
These are common symptoms of brain metastases from kidney cancer, in addition to tinnitus, deafness, hemiplegia or staggering gait, phantom smells, and abnormal or weak unilateral limb sensation.
