these two medical problems are very very different. bell's palsy just follows the nerve pathway on one side of your face often resulting in a droopy eyelid or crooked smile. it tends to get better over time. it would not be common for a brain tumor to present as bell's palsy although some neurological disorders can cause one-side nerve paralysis. a brain tumor can present many different ways from a sudden loss of vision or hearing seizures sudden speech problems severe headaches vomiting inability to walk etc.
can bells palsy symtoms mimic a brain tumor?
