CT demonstration of calcification within old cerebral infarcts.

Calcifications within old cerebral infarcts were demonstrated by CT in three patients who had suffered strokes probably due to emboli from a carotid or cardiac source. In two of them, calcifications were not shown on CT at onset but were first noted on follow-up CT approximately 2 years later in one, and 5 years later in the other. In the third case a large solitary calcification was found on the first CT carried out 13 years after onset. To our knowledge, these findings have not been described previously.
