Diagnosis: Vascular Malformation Vascular malformations are a group of congenital anomalies of vessel morphogenesis that can present at any age.

The International Society for the Study of Vascular Anomalies (ISSVA) updated the classification in 2014 to include capillary, venous, lymphatic, and arteriovenous malformations among the simple vascular malformations.

They are benign but can grow rapidly at times of hormonal stimulation such as puberty, and can be complicated by hemorrhage, thrombosis, or infection.

MRI is useful for mapping the full extent of the lesion.

Ultrasound can be helpful in confirming the diagnosis if the MRI is not definitive, and doppler evaluation can further characterize the type of vascular malformation.

Treatment depends on size and patient symptoms. Many can be treated noninvasively by an interventional radiologist, either using catheter-directed sclerotherapy or embolization.
