Primitive neuroectodermal tumour (PNET) is very rare, especially in adults. We report a 60-year-old man presented with a PNET. The symptoms at the time of diagnosis were intense headache, Broca's aphasia and right hemiparesis. Only an open biopsy was performed. Irradiation of the primary tumour was the main treatment (total tumour dose 59.8 Gy) because of serious haematological side effects due to chemotherapy. The patient tolerated radiation therapy extremely well and his neurological symptoms were improved. 1 month after completion of radiotherapy, MRI showed no regression of the tumour. Clinical deterioration was observed 10 months after the initial diagnosis and the patient died 2 months later. In cases of PNET, initial therapy is surgical bulk reduction whenever possible. Irradiation of the cerebrospinal axis is justified as a routine treatment but, owing to the radioresistance of the tumour, the addition of multiregimen chemotherapy appears to improve survival, according to the literature.
