If there are symptoms of melanoma brain metastasis, patients generally display symptoms of increased intracranial pressure, typically manifesting as headaches accompanied by nausea, vomiting, papilledema, and localized neurological deficits. The tumor in the brain substantively invades the ventricles, easily causing symptoms such as hemiplegia, aphasia, and psychiatric symptoms in patients. If the melanoma occurs in the spinal cord, it can easily lead to segmental sensory and motor disturbances and subarachnoid hemorrhage of the spinal cord. If patients suddenly experience disturbances in consciousness or vomiting, some may develop brain herniation, which is very dangerous. It is recommended that patients seek timely treatment.
