True malformations of the vein of Galen are usually diagnosed within the first weeks of life. They represent less than 1 p. 100 of the cerebral arteriovenous malformations. These true malformations are exceptional in adults but should be known as an endovascular treatment could be performed. ⋯ The angiography enabled the diagnosis of a true malformation of the vein of Galen in its choroidian form. Its high blood flow entails cardiac failure because of a steal phenomenon. An endovascular treatment was declined because of numerous arterial afferences and the potential risks of peroperative haemorrhage.

In this article, we present an overview of the principles, practices and procedures of the presurgical evaluation of the epilepsies in use in our center and in the majority of French teams. Surgery for epilepsy is offered to patients presenting with severe epilepsy with partial seizures. Its aim is to stop the seizures, or to significantly reduce their frequency. ⋯ The phase II is often required and is aimed to precisely define the anatomical localization of the epileptogenic zone and the relationships with a structural lesion. This invasive phase is mainly based on stereoelectroencephalography (SEEG). Finally, the surgical procedure must be adapted according to the distribution and dynamics of the anatomical and functional abnormalities which individually define each case of epilepsy.

Many coagulation disorders have been associated with cerebral venous thrombosis. These disorders may be primary like protein C and S deficiency, antithrombine III deficiency and activated protein C resistance. Antiphospholipid antibodies represent an acquired disorders of coagulation. A prothrombotic state induced by more common factor including oral contraceptive, pregnancy and puerperium increases the venous thrombosis risk.

Parsonage-Turner syndrome is an idiopathic brachial neuropathy affecting the 5(th) and the 6(th) roots. Giant-cells arteritis rarely affects the brachial plexus. In such cases, it can mimic Parsonage-Turner syndrome. We report a case focusing on clinical signs suggesting giant-cell arteritis.

A number of patients admitted to intensive care units for non-neurological disorders develop neuromuscular complications. These patients present with an acute flaccid generalized weakness that may or may not be accompanied by sensory symptoms. There are two main conditions, namely critical illness polyneuropathy and neuromuscular disorder related to the use of neuromuscular blocking agents. ⋯ Critical illness neuropathies often cause difficulty in weaning patients from the respirator. They prolong the stay in the intensive care unit, thereby increasing the risks of complications for the patients. Course of these neuromuscular disorders is usually favorable, however sometimes with sequelae.
