What is Hemangioblastoma?
Hemangioblastomas are slow-growing tumors that can develop on the retina, spinal cord, or blood vessels of the brain. These benign tumors account for about 3% of all spinal tumors. They are not cancerous but can cause significant neurological problems. A hemangioblastoma does not harm healthy tissue and typically can be treated with surgery or focused radiation.
Causes of Hemangioblastoma
The cause for most cases of hemangioblastomas is unknown. About 25% of patients also have von Hippel-Lindau syndrome, an inherited condition characterized by the abnormal growth of tumor in the brain, spinal cord, retina, and kidneys.
Symptoms of Hemangioblastoma
If the tumor compresses the spinal cord or puts pressure on the brain, it can cause several symptoms, including numbness or weakness in the arms or legs. Patients may also have difficulty with balance and coordination and impaired bladder and bowel functions. Other common symptoms include headaches, nausea, and vomiting. In some cases, a hemangioblastoma can cause enough pressure in the brain to cause swelling. Excess fluid in the brain is called cerebral edema, and it can be life threatening.
Diagnosis of Hemangioblastoma
Your doctor may perform a physical exam, blood tests, and imaging scans, including X-rays, MRIs, or a CT scan, to diagnose a hemangioblastoma. A cerebral angiography may also be performed by injecting contrast dye into the bloodstream so that any abnormalities in the blood vessels can be seen on an X-ray. Hemangioblastoma typically becomes symptomatic between ages 30 and 50.
Treatment of Hemangioblastoma
Small hemangioblastoma that don’t cause symptoms may not need any treatment. They may be found incidentally and can be monitored through imaging. Microsurgical resection is a minimally invasive procedure that can remove small tumors. Stereotactic radiosurgery can be used to provide concentrated doses of radiation along with surgery to remove the hemangioblastoma. Using both treatments also decreases the risk of recurrence. Preoperative embolization is sometimes used to cut off the blood supply to the tumor before surgery. Following treatment, you will need to be monitored with regular follow-up exams and MRIs. About one quarter of patients experience a recurrence.
