ABSTRACT
A 45-year-old woman developed signs of meningeal irritation after myelography with iohexol. Her condition improved very quickly (after antibiotic treatment). Rapid improvement, absence of pathogenic organisms in the pre-treatment CSF culture, the level of CSF pleocytosis and protein were in favor of chemical meningitis.

The authors exposed his surgical experience with 10 cases of intrapetrous cholesteatomas specially in view of clinical diagnosis. In fact, no special clinical signs were found except perhaps "facial tic" and intolerable tinnitus in this study. They emphasised upon the necessity of evoked potentials, CT-Scan with contrast and eventually MNR examination specially usefull in cholesteatoma when some doubt subsists.

A non operated aneurysm of the anterior communicating artery enlarged considerably over a seven years period; it finally thrombosed and behaved like a suprasellar tumor. The clinical course, the angiographic evolution and the anatomical examination allowed, in this case, to account for the increase in volume by progressive stretching of the wall, and not by incorporation of a false aneurysmal sack resulting from an encapsulated haematoma. Histologically, the wall of this giant aneurysm showed various changes : on the inner aspect, progressive thickening occurs, due to fibrous organization of mural thrombosis; in the depth, far from the nutrient sources, necrotic atheromatous like foci occur, which isolate an inner leaflet, prone to become nectrotic at a later stage. Distension of such a weakened wall may lead to several consequences; a progressive increase in volume of the aneurysm, partial ruptures with haemodissection starting from the aneurysmal lumen, or even complete rupture of the wall and subarachnoid haemorrhage. On the other hand, circulatory stasis, due to the important increase in volume, may facilitate progressive thrombosis of the aneurysm. The living character of the wall is emphasized by the coexistance of these unfavourable (degeneration, ruptures) and favourable (thrombosis, fibrous organization) features, which continuously influence the spontaneous evolution of the aneurysm.

The authors discuss the approach to adopt in a case of multiple cerebral aneurysm, taking into account the patient's condition and the appearance of the aneurysmal wall. The size of the aneurysm is not an absolute criterion on which the base an assumption as to the site of the rupture and the haemorrhage. Therapy should be based on plastic coating together with clipping of the aneurysm.
