[Syringo-peritoneal shunt].

The pathogenesis of syringomyelia is still under discussion. The authors advocate the role of the pressure of the spinal C.S.

[Cerebral aneurysms complicating bacterial endocarditis. Seven cases (author's transl)].

The authors report seven cases of cerebral aneurysms complicating bacterial endocarditis. The evolution was good in three cases, two of which without sequelae. The bacteries involved were staphylococcus, streptococcus, and enterobacter.

Extra-intracranial anastomosis preliminary to treatment of carotid artery-cavernous sinus fistula.

The authors emphasize the value of extra-intracranial anastomosis prior to occlusion of the cervical segment of the main cerebral arteries, and report a case of carotid-cavernous sinus fistula successfully treated by combined extra-intracranial anastomosis and intra-luminal occlusion of the carotid artery with a balloon catheter.

[Changes in plasma level of corticotropin after intravenous injection of metyrapone. Value of this test in pituitary pathology].

The Metyrapone was given, the morning, in perfusion intravenous of saline serum over 2 hours. A.C.

Role of the pneumo-encephalogram in the diagnosis of spontaneous subarachnoid haemorrhage.

The authors have collected eighteen cases of primary intraventricular lesions revealed by a subarachnoid haemorrhage. Among these cases, the most important are the choroid plexus papillomas followed by ependymomas; some cases have no precise histological interpretation. Generally speaking, cerebral arteriography gives only indirect evidence of ventricular dilation and thus does not confirm the presence of a lesion.

[Spontaneous rhinorrhea due to (congenital?) evagination of arachnoidea in the paranasal sinuses].

Report on two cases of spontaneous, intermittent and long lasting spinal fluid rhinorrhea. The lesion responsible of the spinal fluid fistula is a glio-arachnoid expansion of the convexity of the frontal pole, contained into a fibrous pedicle ; it crosses the dura mater and penetrates, through a well individualized bone orifice, into the posterior wall of the frontal sinus or into an ethmoid-frontal cell. This arachnoid diverticle is not associated with an hydrocephalon.
