Symptoms and treatment of the von hippel lindau syndrome vhl
Anyone with an aunt, uncle, cousin, or grandparent with VHL may also be at risk. The following are offered as general guidelines for possible treatment therapies.

How is VHL inherited? New therapies include anti-angiogenesis blood vessel starving medications, which stop blood vessels from growing, and targeted therapies that help your body fight the disease on a molecular level. Other types of tumors develop in the adrenal glands, the kidneys, or the pancreas. They are also at an increased risk of developing a type of kidney cancer called clear cell renal cell carcinoma and a type of pancreatic cancer called a pancreatic neuroendocrine tumor. Treatment of most cases of VHL usually involves surgery to remove the tumors before they become harmful. People with VHL also have an increased risk of developing clear cell renal cell carcinoma , which is a specific type of kidney cancer; pheochromocytoma , which is a tumor of the adrenal gland ; and a type of pancreatic tumor known as pancreatic neuroendocrine tumor. This allows physicians to direct the extensive screening process only to those who actually manifest the germline mutation. Once the lesion has been removed, the cyst will collapse. This is called an adrenalectomy. Screening guidelines for systemic disease include complete blood count to look for polycythemia vera; measurement of urinary catecholamine metabolites vanillylmandelic acid, metanephrines and total catecholamines to detect pheochromocytomas; urinalysis for hematuria; and urine cytology to detect RCC. Related Disorders VHL is a complicated disease, which causes tumors to grow in 10 different parts of the body: kidneys, adrenals, pancreas, brain, spine, retina, inner ears, reproductive tract, liver, and lungs. If you have VHL and develop eye problems or signs of a neurological problem, such as headaches, your doctor may recommend a thorough eye exam or MRI or CT scans of the brain. The result is increased levels of the various growth factors allowing for increased blood vessel growth angiogenesis and the formation of tumors. What research is being done?
The NIH's National Cancer Institute conducts research aimed at treating kidney tumors in individuals with VHL, as well as studies to identify gene mutations in people who are at risk of developing the disease.
Did You Know?
With juxtapapillary and endophytic RCH, other entities to be considered are disc edema, ischemic optic neuropathy and choroidal neovascularization. Even pheochromocytomas that do not appear to be active or causing symptoms should be considered for removal, ideally prior to pregnancy or non-emergency surgery.
Like all surgeries, surgery for VHL disorders is most successful when performed by a specialist with a great deal of experience in the particular procedure.
In addition, the appearance and severity of VHL lesions are so different between people that many members of the same family may have only some relatively harmless issue, while others may have a serious illness.
If both adrenal glands are removed, you will need to take medicine to give your body the hormones that usually are made by the adrenal gland.
