Stroke complications and mimics: A video guide for radiologists

A new educational video reviews stroke complications like hemorrhagic conversion—masslike hemorrhage >1 cm with mass effect—and CT perfusion mimics, noting that patients with petechial hemorrhage may safely continue anticoagulation.

• The video, part of an introductory stroke series, teaches recognition of hemorrhagic conversion versus petechial hemorrhage and common stroke mimics on CT perfusion.
• Distinction between hemorrhagic conversion (>1 cm, mass effect) and petechial hemorrhage (small, may not require anticoagulation cessation) is highlighted.
• As an educational resource, it reflects one neuroradiologist's teaching approach and is not a formal guideline or systematic review.
