Vascular anomalies: Hemangiomas and beyond - Part I, fast-flow lesions

OBJECTIVE. The purpose of this study was to review the medical literature and the current classification of vascular anomalies to clarify common misconceptions and provide guidance for imaging and treatment. In this first article of a two-part series, we focus on the fast-flow vascular anomalies. CONCLUSION. Nonuniformity of terminology across the medical literature hampers understanding of the vascular anomalies. A familiarity with the classification and biology on which this terminology is based is essential for accurate and precise diagnosis.
