Vascular tumors and malformations encompass a spectrum of pathology that varies widely in presentation, severity, and treatments. Although typically a clinical diagnosis, accurate classification of lesions is often challenging. Imaging plays an integral role in confirming the clinical diagnosis, determining the extent of disease and planning treatment strategies. Ultrasound and MRI constitute the backbone of diagnostic imaging in vascular anomalies; however, other modalities such as radiography, computed tomography, and conventional angiography can play a role in certain situations.
