%X Vascular malformations (VM) are vascular spaces lined by flat epithelium with an estimated prevalence of 4.5% in the population (1). It is usually present at birth, with enlargement proportional to childĄ¯s growth, but sudden expansion may be seen in infection, hormonal changes or trauma (2). They are the most common child hood soft tissue masses (3). VM occurs due to errors in morphogenesis however they exhibit normal cell turnover unlike vascular tumors (4-6). These lesions can be diffuse or focal, simple or combined based on subtype of vessels involved (7). Appropriate distinction between different VM lead to improved management of lesions, therefore VM can be classified by the type of vessel component (capillary, venous, lymphatic, arterial and hybrid subtype) and according to blood flow dynamics (high and slow flow lesions) (8). Moreover, this classification system combined with detailed physical exam and imaging can have up to 90% accuracy of diagnosis (9). Doppler ultrasonography (US) has been the first diagnostic modality utilized in the management of patients with VM, due to low-cost, non-ionizing technology and the ability to provide lesionsĄ¯ flow characteristics (10), however magnetic resonance imaging (MRI) has proven advantageous to define extent of the lesions and guide appropriate treatment (11)
