title: Calcified embolism: a rare cause of cerebral infarction.
abstract: Calcified cerebral emboli (CCE) are a rare cause of stroke and these emboli can be identified on a CT scan of the brain performed for the initial evaluation of stroke. In this report we present a patient who developed a CCE following cardiac catheterisation that lodged in the left middle cerebral artery with resultant right hemiparesis and aphasia. The calcified embolus was seen on CT but could not be identified on MRI. Predisposing factors for CCE include angiography and valve or vessel wall calcification. The natural history and response to standard therapy in patients with CCE as compared with stroke of other aetiologies have not been studied until now. Increased awareness and ability to identify calcified emboli will help us to have an improved understanding of strokes resulting from CCE.
