Spontaneous vertebral artery dissection in an elder patient: a case report

Vertebrobasilar artery dissection (VBD) is a rare cause of posterior ischemic strokes. It is more likely to occur in young patients with a history of traumatism or hereditary connective tissue disorders. Spontaneous VBD is rare, especially in elder patients. This paper aims to report the case of an old patient that presented with a posterior ischemic stroke due to a spontaneous vertebral artery dissection (SVAD), linked to atherosclerosis. The diagnosis of SVAD was made by Magnetic resonance imaging (MRI) which is the gold standard technique to diagnose this pathology in a short time so the patient could receive adequate treatment

Transient ischemic attack due to multiple spontaneous calcified embolus of the cerebral arteries on a calcified mitral and aortic stenosis

We report a case of calcified mitral and aortic stenosis revealed by a reversible ischemic stroke. A 59-year-old male patient, with background of hypertension, kidney failure, diabetes, and dyslipidemia, presented with neither acute onset of right-sided hemiparesis without aphasia nor any loss of consciousness. Head computed tomography (CT) revealed multiple rounded and amorph calcified high-density calcifications within the distal segments of both sylvian and posterior cerebral arteries. Angiographic CT of the carotids didn't reveal any stenosis or atherosclerotic plaques. Thoracic CT showed massive mitral and aortic valvular calcifications with a left ventricular hypertrophy
