title: Extensive primary Ewings' sarcoma in the greater wing of the sphenoid bone.
abstract: We describe a rare case of an extensive primary cranial Ewing's sarcoma located in the greater wing of the sphenoid bone with extension to the orbit, the endocranium, the parapharyngeal and infratemporal space. The patient presented with diplopia, anosmia and prolapse of the left eye. He was given chemo- and radiotherapy and was free of symptoms on re-examination 1.5 years later. The prognosis of Ewing's sarcoma in the absence of surgery is uncertain, but prompt treatment appears to have a satisfactory therapeutic outcome. In the future, more cases should be studied in order to investigate the biological behaviour of a primary cranial Ewing's sarcoma.
