Imaging and management of vascular malformations

Vascular malformations are a diffuse collection of abnormalities that are usually present at birth but may present any time during childhood or as an adult. Historically terminology has been complicated and used interchangeably causing confusion to patients and clinicians alike; however, a structured internationally agreed classification system exists. It is not uncommon for patients with vascular malformations to be referred to various specialties without obtaining a correct diagnosis and appropriate treatment. Vascular malformations can occur anywhere within the body and all patients will require imaging at some stage; therefore, it is important for all radiologists to be aware of the correct terminology and imaging characteristics. This review discusses classification and illustrates salient imaging findings and the modern approach to treatment of vascular malformations.
