- Vascular malformations include a broad range of diverse lesions that can affect every region of the body and can lead to serious illness in both adults and children.
- They usually grow proportionally with the age and show no regression.
- Magnetic resonance (MR) imaging in combination with MR angiography performed with intravenous administration of gadolinium-based contrast has an important role in evaluating the extent of lesions, particularly deeper lesions, and their relationship to adjacent structures
- Vascular malformations are developmental abnormalities, which usually do not present before puberty.
- MRI with dynamic contrast-enhanced sequences is the mainstay of diagnosis and characterization of these lesions.
- Goals of imaging peripheral vascular malformations are twofold: to define the anatomic extent of the lesion and to distinguish low-flow vascular malformations from high-flow vascular malformations.
- The most important characterizing feature of vascular malformations is whether the lesion is a high-flow or low-flow vascular malformation, because direct percutaneous sclerotherapy is described as the treatment of choice for low-flow vascular malformations.
According to the preponderant vascular channels, vascular malformations are classified as venous, lymphatic, capillary, arterial or combined.
