We have examined, with systematic serial computerized tomography (CT) studies, 6 patients with persistent ischemic cerebral infarction. The CT of the ischemic cerebral infarction shows, during the third week, an isodense area. We have called this phenomenon "fogging effect" because at this effect and the CT report could be negative. The possibility of a false negative can be avoided by a control study with contrast medium: the infarction has an intensive contrast enhancement.
