[Pourfour du Petit syndrome and intracranial aneurysms (author's transl)]

A 52 year old female suffered for more than 20 years from a recurrent pulsating headache on the left side. Clinical examination showed the retraction of the superior eyelid and mydriasis on the left. Exophthalmometry revealed 17 mm of protrusion for each eyeball. Angiographic investigations showed two little aneurysms: one of the anterior comunicating artery, the second of the left middle cerebral artery. In view of the clinical and angiographic findings the authors discuss the pathogenetic mechanisms of such oculo-sympthetic syndrome.
