Four cases of brain lesions which developed symptoms in the region of mouth and jaw are reported. Lesions of three cases were brain tumors, which were acoustic neurinoma, lipoma, meningioma, and cerebral infarction. Symptoms of the mouth and jaw were consciousness of tongue and lip, trigeminal neuralgia, spontaneous pain of eye and maxilla. We are not well-versed in these illnesses. This paper describes the relation of such illnesses with symptoms in the region of the mouth and jaw.
As mentioned above, when neuralgia and consciousness of oral mucosa and face are found in patients, we should consider the possibility of brain lesions.
