[Migratory hyperdense posterior cerebral artery sign following intravenous thrombolysis].

CONCLUSIONS: Evidence of posterior cerebral artery hyperdensity is a rare radiological finding associated with an increased volume of ischaemic stroke. A computed tomography scan of the head in the acute phase is essential to try to clarify its causation. Calcium emboli are an under-diagnosed cause of stroke and occur spontaneously in a large proportion of cases. If calcium embolism is suspected, a study must be conducted in search of a carotid, valvular or aortic arch pathology. Migration of the arterial hyperdensity towards distal is associated with a better prognosis. This case presented good progress in contrast to the poor prognosis described in the literature in cases of arterial hyperdensity as an early marker of stroke in the acute phase.
