Magnetic resonance angiography is now a technique commonly used in neurologic practice. We give a brief overview of the biophysical principles of this technique. ⋯ The purpose of this review is to concentrate on the role of magnetic resonance angiography in patients with various carotid artery diseases and to specify possibilities, limitations and risk of misinterpretation. Magnetic resonance angiography is a major, still evolving technique.

Bleeding stomal varices is a rare complication of portal hypertension. We report the case of a cirrhotic patient, with a history of colonic adenocarcinoma, who had recurrent bleeding stomal varices. ⋯ Twenty six months later only one stomal hemorrhage was noted. This suggests that transjugular intrahepatic portosystemic shunt and stomal varice embolization is effective in case of recurrent bleeding of stomal varices.

To evaluate the preoperative MRI criteria of a sinus cavernous invasion by a pituitary adenoma. ⋯ Except the total encasement of the intracavernous ICA, the cavernous sinus can be invaded when the lateral tangent of the supra and the intracavernous ICA is crossed, and also when the percentage of ICA encasement exceeds 25%.
