![]() They grow slowly and may extend deeper into nearby tissues and structures, causing problems. Vascular malformations are present at birth but may not be noticeable until childhood or even adulthood.When hemangiomas are large or affect function or cause pain or other problems, they usually can be managed with a medication that makes them shrink faster. These tumors rarely cause problems and usually go away without treatment. They grow rapidly for the first six months of an infant’s life. Strawberry hemangiomas typically appear after birth. They form when blood vessels clump together underneath the skin. Hemangiomas are a type of noncancerous (benign) vascular tumor.They both can cause birthmark-like blemishes, but there are differences: Vascular malformations and hemangiomas result from irregularities in blood vessels (vascular anomalies). What’s the difference between vascular malformations and hemangiomas? Lymphatic malformations: Dilated lymphatic channels forming fluid-containing cysts tend to develop in the soft tissues of your face, neck and axillary (arm pit) regions.Blood moves slowly through these caverns. Cavernous malformations: Tightly packed capillaries in your brain have long “caverns” ( cavernous malformations).But occasionally, they cause a hemorrhage. Most capillary telangiectasias don’t cause problems. Capillary telangiectasia: These small areas of enlarged capillaries tend to develop in the brain.Instead of connecting to capillaries, the arteries pump blood directly into the veins through a cluster of channels called a nidus. Arteriovenous malformation (AVM): An AVM is a tangle of arteries and veins that connect incorrectly.Veins carry blood back to your heart to get oxygen. ![]() Venous malformation: The most common type of vascular malformation, a venous malformation, develops in a vein.Healthcare providers determine the type of vascular malformation based on the affected blood vessels. Or they may develop in practically any part of your body, including your brain or spine. Vascular malformations may appear as birthmarks on an infant’s skin. What are the types of vascular malformations? They may also develop in lymphatic vessels in the lymphatic system.Īffected blood vessels may include one or more of the following structures: Vascular malformations can affect any blood vessel in your circulatory system. Vascular malformations that cause pain, impair function such as vision or activities or cause bleeding or other problems may need treatment. Rarely, vascular malformations develop during adulthood after trauma or another incident. Others look like birthmarks or red blemishes. Some vascular malformations develop on your face or neck or near your brain or spinal cord. They may present as a soft tissue mass, pain, swelling and/or skin discoloration. Vascular malformations can develop in any part of your body - from your head to your toes. These changes are typically present at birth but frequently may not become evident until later in life during childhood or even in adulthood. Vascular malformations are abnormalities that involve blood vessels.
