Hemangiomas associated with PHACE syndrome are usually small or not there at birth, but are easier to see during the first days to weeks of life. They can grow quite fast.

Hemangiomas linked with PHACE syndrome tend to cover a large area of the face, head or neck, either as one lesion or as many single lesions. They are usually over certain facial areas called segments.

If the medical history and the actual exam of the hemangioma look typical for PHACE syndrome, more tests are ordered to confirm the diagnosis. These tests may include: 

• Ultrasound
• Magnetic resonance imaging (MRI)
• Magnetic resonance angiography of the brain (MRA)
• Echocardiogram (echo) or electrocardiogram (EKG) of the heart
• Eye exam by an eye doctor  

 Other tests may be needed for diagnosis and treatment.

As it grows, the hemangioma can break down skin, distort facial features or get in the way of other vital functions, such as breathing, vision, and hearing.

Other complications will depend on what other structures are involved. These could include developmental delay, seizures, headaches, and abnormal muscle tone if the brain is involved.

Usually the hemangioma requires medical therapy. The child may need other therapies, depending on what other organs or structures are involved.

PHACE syndrome needs to be managed by a multidisciplinary team of experts. Additional specialties such as cardiology, ophthalmology, neurology, and neurosurgery may need to be involved.

The team of experts pays close attention to how these children develop throughout the school-age period.
