title: [Clinical case of the month. Rendu-Osler-Weber disease: a rare case of stroke in the young].
abstract: Rendu-Osler disease or hereditary hemorragic telangiectasia is a group of autosomal dominant diseases characterized by angiodysplasic lesions in the skin, mucous membranes and viscera with risks of recurrent bleedings. Neurological complications have been described in 10-30% of these patients, most often hemorrhagic or septic. More exceptionally, ischemic strokes occur in these patients, particularly if they have pulmonary arteriovenous malformations. We report the observation of a 25 year old man who developed a latero-protuberantial stroke. The explorations revealed pulmonary AV malformations and nasal telangiectasias that led to the diagnostic of Rendu-Osler disease. This affection should be considered as a potential cause of cerebral ischemic attack, particularly in young patients without risk factors.
