title: [A dangerous combination for stroke in young patient: assimilation of the atlas and anti beta2-glycoprotein I antibodies].
abstract: A 45 year old male was admitted to the hospital for unsteady gait and dizziness. The brain CT showed bilateral cerebellar ischemic stroke. The MRI corroborated the stroke in the cerebellum with a third acute ischemic stroke in the pons. The laboratory work up showed a positive anti beta2-glycoprotein I antibodies. The cerebral angiogram showed the territories occluded and also a rare malformation of the cranium vertebral junction called assimilation of the atlas. We concluded that due to the turbulence created in the V3 segment of the vertebral artery surrounding the atlas, the presence of the anti beta2-glycoprotein was the cause of the infarction in this patient.
