Brain metastases from hepatocellular carcinoma are more dangerous, with the tumor occupying space in the skull and causing compression of surrounding tissues.
Different locations within the brain can lead to different symptoms. When it occurs in the parietal lobe, it will show loss of sensory ability, inability to discriminate, loss of muscle tone, and muscle atrophy. When metastasis to the main lateral parietal lobe is (when), it will show loss of ability to discriminate direction and position, loss of ability to read, write and count, etc. When liver cancer brain metastasis occurs in the occipital lobe, the patient will develop hallucinations, and when metastasis to the main lateral occipital lobe anteriorly manifests as not recognizing the color and form of objects.
Second, brain metastases from hepatocellular carcinoma can cause increased intracranial pressure, which can lead to headache, optic nerve papilledema, vomiting, etc. The headache is paroxysmal and becomes persistent as the disease progresses, intensifying during activities such as coughing, sneezing, bending over, and head bowing. Optic nerve papillar edema has no visual impairment in the early stages, but with time, symptoms such as loss of vision and narrowing of the visual field toward the center may appear. Vomiting often occurs with severe headaches, and nausea and vomiting occur, which can cause dehydration in patients. It can also lead to nerve paralysis, seizures, aphasia, bradycardia, and increased blood pressure.
