The authors report on a case of "benign" intracranial hypertension due to bilateral thrombosis of the lateral sinuses and internal jugular veins of infectious origin (otitis). A venous by-pass was established between one of the lateral sinuses and an external jugular vein. As early as the first post-operative week, the intracranial pressure was reduced and the visual disorders regressed. Such venous by-passes, now made possible by micromicrosurgical techniques, can be suggested for treating occlusions of the intracranial sinuses due to thrombophlebitis, traumatisms or tumours.
The authors report 1 case of cerebellopontine angle chondroma. In the World literature 12 cases are already described. They insist on the difficulty of the diagnosis and on the length of clinical evolution (12 years). The CT Scan will certainly transform this pathology by early detection of small tumors at extra dural stage.
The present paper reports a case of intracranial hypertension secondary to thrombophlebitis of the two transverse sinuses and internal jugular veins in which microsurgical revascularization was attempted. This was carried out by means of a bypass graft inserted between the right transverse sinus and the superficial jugular vein. As early as the first post-operative week, intracranial pressure improved and visual disorders regressed. This type of venous revascularization using microsurgical techniques should contribute to more successful and lasting results in cases of sinus occlusions of thrombophlebitic, traumatic or tumorous origins.

The authors report a case of malignant ependymoma of the terminal medullary cone and the cauda equina, presenting at the stage of metastatic diffusion to the whole spinal axis. They stress the pathological interest of such a form and its extreme rarity.
The authors report the case of an eight-year-old girl hospitalised for severe headache with paroxysmal left otalgia, vomiting, aprexia, paralysis of the left 6 th cranial nerve and slight left facial weakness. Left carotid arteriography revealed a very large aneurysm of the internal carotid, involving its entire intra-petrous and intra-cavernous course. Treatment consisted of ligation of the internal carotid in the neck. Postoperative angiographic studies showed complete exclusion of the aneurysm, and it was unecessary to carry out "trapping" by ligation of the supra-cavernous carotid, as had initially been envisaged. The postoperative course was uneventful : immediate disappearance of otalgia, secondary complete recovery of the oculo-motor involvement and facial paresis. The absence of any infections or traumatic past history, together with the young age of the patient, represent arguments in favour of the congenital origin of this intra-petrous carotid aneurysm.
The authors report a case of post-traumatic pseudo-aneurysm of the pericallosal artery in an 11 year old child. The lesion was secondary to a perforating wound of the roof of the right orbit, the eye itself being undamaged.

The authors report 13 cases which permitted them to discuss the clinical signs, which were multiple, completed by further investigations of which the most important was lipiodol myelography. The treatment included usually surgical operation accompanied by radiotherapy, chemotherapy and sometimes immunotherapy. This combined treatment gave a better prognosis espeically in patients operated at stages I, II and III, and we obtained 25% favourable results.
