[Paraganglioma of the cranial vault. Apropos of a case].

The authors report the case of a 40 years old woman with a fronto parietal tumefaction and intracranial hypertension caused by a paraganglioma of the cranial vault. The clinical follow up is marked by rapid local recurrence of the tumor after complete excision. Usually paragangliomas arise in any area of the body where paraganglionar structures are situated (glomus jugulare, carotid glomus, vagus nerve). Other rare locations have been reported and remain difficult to be explained. The location at the cranial vault is exceptional. this tumor would probably arise from the paraganglionar cells which migrate from the neural crest following the trigeminal branches particularly the ophtalmic division.
