previously visited HEMORRHAGIC TRANSFORMATION OF AN MCA INFARCTION Random Case

Findings: Hemorrhagic conversion of the previously identified region of infarction in the posteriosuperior parietal lobe.
Diagnosis: 62 year old male: with history of right sided MCA stroke presented for followup.
Discussion:

Hemorrhagic transformation of an infarct can be seen in up to half of all cases.  Anticoagulation and thrombolytics can often contribute.  1 to 2 weeks post-infarction is the peak time for this to occur, and usually first manifests as petichial hemorrhage outlining the gyral contours in the region of prior infarction. 

Typically for hemorrhagic transformation, you will not see intraventricular hemorrhage.  If you do, suspect other causes such as hypertensive intracerebral hemorrhage or AVM.
