Noncompliant with chronic transfusions.
Normal imaging but stroke based on clinical symptoms of hemiparesis lasting 4 weeks.
Had MRA studies prior to initial stroke as part of enrollment in the STOP study.
Transferred to our institution in 1999. Review of records from parent institution showed no recurrent CVE. Has not had follow-up scans.
