Parkes Weber Syndrome | Diagnosis & Testing

How is Parkes Weber syndrome diagnosed?

Doctors can sometimes see evidence of Parkes Weber syndrome (PWS) in a prenatal ultrasound, and the capillary malformation (“port-wine stain”) is almost always apparent when your child is born.

If a child is older and you believe he has PWS, the first step to making a diagnosis is a complete medical history and a thorough physical exam. In many cases, that initial exam gives us enough information to diagnose PWS.

What tests may my child need?

If there’s any doubt, your doctor may recommend one or more of the following imaging tests, which can help determine the correct diagnosis and the appropriate next steps in treatment:

  • Magnetic resonance imaging (MRI): This high-resolution scan shows the extent of the hypertrophy (overgrowth) of tissue and gives your doctor information about what problems it may be causing.
  • Angiogram: In this study, an interventional radiologist injects a dye into your child's blood vessels, giving doctors a detailed view of the blood vessels in the affected limb.
  • Echocardiogram: An echocardiogram allows your child’s doctor to check the condition of her heart.

After we complete all necessary tests, our team of vascular anomalies specialists will review and discuss what they have learned about your child's condition. Then we will meet with you and your family to discuss the results and outline the best treatment options for your child.
