Vascular malformations are congenital lesions that are present at birth and do not regress. However, they often present later in life. They are subdivided into two categories: (1) slow- or low-flow and (2) fast- or high-flow malformations. Low-flow malformations contain combinations of capillary, venous, and lymphatic components. Venous malformations can occur anywhere in the body, but are most frequently seen in the head and neck (40%). These lesions present in a variety of ways, from a vague blue patch to a soft blue mass, which may be single isolated or may occur in multiple areas. Treatment depends on the type of lesion, the location, degree of involvement, and the clinical symptoms. Here we are report the imaging and histopathologic findings in a patient with multiple venous malformations affecting the left side of the face and trunk.
