Findings

No curated finding names frontonasal arteriovenous malformation yet. Everything below is reference data from Mondo, HPO and GenCC, not evidence about what affects it.

Definition

Frontonasal arteriovenous malformation is a rare vascular anomaly characterized by abnormal communication between arteries and veins, bypassing the capillary bed, located in the frontonasal area. It may present with intermittent nasal bleeding, blurred vision, pustule formation and/or disfigurement. Overlying skin may be of normal appearance or may manifest a red, pulsatile mass with local rise of temperature. Other features may include pain, ulceration, excessive growth and/or congestive heart failure.
