Vascular anomalies represent a spectrum of disorders ranging from simple "birthmarks" to life-threatening entities. Incorrect nomenclature and misdiagnosis are common in patients with these anomalies. The objectives of this educational presentation are to provide radiologists with a comprehensive understanding of the ISSVA (International Society for the Study of Vascular Anomalies) classification and to enhance their familiarity with the clinical and imaging features of commonly encountered soft tissue vascular anomalies in pediatric patients. Special emphasis is placed on emphasizing the practicality of ultrasound as an effective diagnostic tool. The ISSVA has been updated with the recognition of causal genetic mutations, most recently revised in May 2018. The main organizational principle of this classification divides vascular lesions into: vascular tumors (neoplastic): benign, locally aggressive/borderline, and malignant; vascular malformations (non-neoplastic): simple, combined, major named vessels, and associated with other anomalies; unclassified anomalies (unclear whether tumor or malformation).
