Abstract
According to the International Society for the Study of Vascular Anomalies (ISSVA)
classification, vascular anomalies include a diverse range of pathologies, classified
as either vascular tumors or vascular malformations. This classification, last revised
in 2018, aims to explain the biological basis of vascular lesions and help clinicians
to manage the anomalies. In vascular tumors, there are proliferative changes of endothelial
cells, while vascular malformations primarily consist of structural vascular abnormalities.
Infantile hemangioma is the most common soft-tissue vascular tumor. Vascular malformations
are an extensive group of malformations of the arterial, venous, and lymphatic systems,
either in isolation or in combination. Radiological evaluation plays a key part in
the management of pediatric patients with these entities. The understanding of sonography
and magnetic resonance imaging findings entails its correlation with clinical findings
at the time of scanning.
