Glioblastoma multiforme is the most common primary brain tumor, despite an aggressive clinical course, less than 2% of patients develop extraneural metastasis. We present a 72-year-old male diagnosed with a right temporal glioblastoma due to headache. He underwent total gross resection surgery and after that the patient was treated with adyuvant therapy. Five months after the patient returned with trigeminal neuralgia, and MRI showed an infratemporal cranial mass which infiltrates masticator space, the surrounding bone, the temporal muscle and superior cervical and parotid lymph nodes. The patient underwent a new surgery reaching partial resection of the temporal lesion. After that the patient continued suffering from disabling trigeminal neuralgia, that's why because of the bad clinical situation and the treatment failure we decided to restrict therapeutic efforts. The patient died 3 weeks after the diagnosis of extracranial metastasis.
