Role of imaging in the diagnosis of vascular malformations vascular malformations

Imaging evaluation of vascular malformations (VM) is paramount for proper diagnosis and treatment planning. These lesions often present as complex vascular masses with arterial, venous and lymphatic components, requiring the use of advanced imaging modalities for full anatomical characterization. Symptoms also depend of the location and flow characteristic of such lesions and range from: asymptomatic to severe forms of cardiac arteriovenous shunting. We present an overview of the diagnostic work-up of VM per most recent classification systems and describe imaging characteristics of such lesions at ultrasonography (US) and magnetic resonance imaging (MRI) as a diagnostic tool for work-up of such patients.
