What is von Hippel-Lindau disease?
Von Hippel-Lindau disease is a genetic disorder What is a genetic disorder? Your genes are the chemical codes that control everything about how your body works, how it's made, and what it looks like. People have over 20,000 different genes. Every cell in your body has... read more that causes tumors to form in several organs. The most common tumors are made out of blood vessels (angiomas) and form in the brain and back of the eyes (retina). Other types of tumors form in the adrenal glands, kidney, liver, and pancreas. The tumors may or may not be cancerous.
Symptoms depend on the location of the tumors and typically appear between ages 10 and 30
Genetic testing is done on your child and also on all members of the immediate family
Treatment is surgery to remove tumors when possible
Your child will need frequent imaging studies to identify tumors because early treatment is most effective
People with von Hippel-Lindau disease are at risk of kidney cancer as they get older.

Sometimes, the baby inherited the abnormal gene from a parent. Other times, the baby is the first person in the family to have the abnormal gene.
What are the symptoms of von Hippel-Lindau disease?
Symptoms usually begin to show between the ages of 10 and 30 years.
Symptoms depend on the size and location of the tumors. Your child may:
Feel dizzy and weak
Have high blood pressure
Have difficulty hearing
Have vision loss, if a tumor in the back of the eye enlarges
What are the tests for von Hippel-Lindau disease?
If doctors suspect your child has von Hippel-Lindau disease, they do:
CT scans Computed Tomography A CT scan uses a large machine shaped like a large donut to take x-rays from many angles. A computer then takes the x-rays and creates many detailed pictures of the inside of your body.

If these tests suggest von Hippel-Lindau disease, doctors do other imaging tests to look for other tumors. They also do genetic tests to check for the abnormal gene.
Family members also need to be examined and have tests to see if they have the disorder too.
Because tumors can appear later on, people are checked regularly for tumors.
How do doctors treat von Hippel-Lindau disease?
Tumors are removed with surgery
Blood vessel tumors in the back of the eye usually are treated with lasers or freezing
Doctors do tests to check for new tumors every 1 to 2 years. There's no cure, but treatment can help your child avoid blindness or brain damage. Complications from brain tumors or kidney cancer can be fatal.
How can I prevent von Hippel-Lindau disease?
Usually this disease cannot be prevented.
If you have von Hippel-Lindau disease in your family and you're planning on having children, you can get genetic tests to see if you carry the gene that can cause this disease. Genetic counseling can help determine the risk of your child having the disease.
