Abstract
Ultrasound and colour flow imaging play a major role in the diagnosis of superficial vascular and lymphatic lesions in children. For deeper and more extensive lesions, magnetic resonance imaging is often complementary to ultrasound. This review aims to provide an understanding of the biological behaviour and typical imaging appearances of haemangiomas, arteriovenous malformations, venous malformations, lymphatic malformations and similar lesions which may occur in the neck in childhood.
