1. Headache due to increased intracranial pressure
Early on, pain may present as localized distending headache on the side of the lesion, later progressing to persistent severe diffuse headache, worst in the early morning and exacerbated by coughing or defecation.
2. Nausea and vomiting due to increased intracranial pressure
Often accompanies headache and may present as projectile vomiting, potentially causing dehydration, due to stimulation of the medullary vomiting center by elevated intracranial pressure.
3. Papilledema and visual impairment
Impaired venous outflow in the fundus leads to papilledema, causing blurred vision and visual field constriction and potentially progressing to secondary optic atrophy.
4. Motor dysfunction
Compression of the motor cortex or corticospinal tracts can cause progressive contralateral weakness progressing to hemiplegia, with abnormal muscle tone and positive pathological reflexes.
5. Sensory dysfunction
Involvement of the parietal sensory cortex can cause contralateral numbness and decreased sensation, with reduced sensitivity to temperature and pain.
6. Language impairment
Damage to the dominant-hemisphere language centers can cause expressive or receptive aphasia, with difficulty in speech production or comprehension.
7. Seizures
Tumor-related cortical irritation may trigger abnormal discharges, leading to focal or generalized seizures, and may be the initial presentation in some patients.
8. Neuropsychiatric and cognitive changes
Frontal or temporal lobe involvement may cause slowed responses, memory decline, personality changes, and, in severe cases, hallucinations or aggressive behavior.
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that brain metastasis is a severe complication of advanced cancer. Tumor destruction of brain tissue can cause life-threatening intracranial hypertension and disabling sequelae such as paralysis and aphasia. Symptoms warrant immediate standardized evaluation and management. Individualized MDT-based multimodal therapy can effectively control disease, relieve symptoms, prolong survival, and improve quality of life.
