title: [Transformation of cerebral infarction into hemorrhage during x-ray computed tomography in a patient under anticoagulant treatment].
abstract: Repeated CT scans provide the only means of confirming the initial ischemic nature of a cerebrovascular accident and its eventual course towards a hemorrhage. Precise data can be obtained as to the frequency of this complication as a function of factors such as the embolic origin of the infarct or associated anticoagulant therapy. The present case shows that contrast medium, at least in patients receiving anticoagulant treatment, may constitute a risk factor by increasing the possibility of transformation of a pale infarct into a hemorrhagic one. Possible relevant properties of iodized contrast media with respect to this type of complication are considered.
