Description:VM venous malformation Venous malformations are a congenital anomaly that, though present at birth, may become clinically apparent at any time throughout the lifespan. They are thought to be caused by an error in vascular morphogenesis, secondary to hereditable or sporadic mutations, altered gene expression, or environmental factors. Less frequently, they may ulcerate or bleed, although this is usually in response to trauma and more typically associated with arteriovenous malformations. They may also impede speech and swallowing and obstruct the upper airway, though most are asymptomatic. Multiple, rounded signal intensity voids representing phleboliths may be noted. Because they contain dilated, slow-flow vascular spaces, enhancement of the channels is typically seen after intravenous administration of gadolinium.
