Hemangioblastoma is successfully treated in Israel thanks to world-class neurosurgery and advanced technologies that allow for the removal of even complex tumors with high precision and minimal risks. Leading specialists with years of experience in surgeries on the blood vessels of the brain and spinal cord use the most modern methods, including microsurgery, endoscopic techniques, and stereotactic radiosurgery. A personalized approach takes into account the size, location of the tumor, age, and overall health, making treatment as effective as possible.
The clinic offers not only world-class medical care but also comfortable accommodation and support from a personal coordinator. This ensures not only effective treatment but also makes the entire process as comfortable as possible for the patient.
About the Disease
Hemangioblastoma is a benign tumor composed of blood vessels that develops in the central nervous system, most often in the cerebellum. The causes of the disease are not fully understood; however, it is known that genetic predisposition plays a significant role, especially in von Hippel-Lindau syndrome. This tumor grows slowly and may remain asymptomatic for a long time, but as it increases in size, it begins to exert pressure on surrounding tissues, causing various neurological symptoms.
Patients may experience headaches, dizziness, coordination disturbances, weakness in the limbs, and balance problems. Additionally, the tumor can cause increased intracranial pressure, leading to symptoms such as nausea, vomiting, and blurred vision. In some cases, hemangioblastomas may bleed, resulting in more severe complications such as seizures and loss of consciousness.

Treatment Methods
At the Ichilov clinic, the choice of treatment method for hemangioblastoma is based on a precise assessment of the tumor's location, size, and neurological risks, allowing for the creation of an individualized protocol for each case.
Microsurgical Removal
When the tumor reaches a size that begins to compress surrounding structures of the brain or spinal cord, microsurgical removal becomes the preferred choice. The operation is performed using intraoperative neuro-navigation, which creates a three-dimensional map in real-time and allows the surgeon to see the tumor boundaries with millimeter precision. Modern microscopes with high magnification and fluorescent visualization help distinguish altered tissue from healthy tissue, which is critical when working near vital centers. Neurophysiological monitoring throughout the operation tracks the functions of the spinal cord and nerve roots, instantly signaling any risk.
Stereotactic Radiosurgery
Small hemangioblastomas located in difficult-to-reach areas of the brainstem or upper segments of the spinal cord often require a non-contact approach. The Gamma Knife system or linear accelerator directs multiple thin beams of radiation that intersect precisely at the tumor volume, creating a high dose of radiation with minimal impact on surrounding tissues. Planning the session takes several hours and involves overlaying MRI and CT data to build a virtual model. Radiation lasts from several minutes to an hour, the patient remains conscious, and a special mask or frame stabilizes the head with sub-millimeter accuracy. The effect develops gradually, with the tumor's vessels becoming necrotic over several months.
Embolization of Tumor Vessels
In hemangioblastomas with pronounced vascularization, where the tumor is literally permeated by a network of enlarged vessels, embolization serves as a preparatory stage before surgery. An interventional neuroradiologist accesses the feeding vessels of the tumor through a microcatheter inserted via the femoral artery and injects an embolizing material that blocks blood flow. The entire procedure is performed under angiographic control, which shows the movement of contrast in real-time through the vascular system. Reducing blood supply to the tumor a day before surgery lowers the risk of massive bleeding and makes removal safer. In some cases, embolization may be used as a standalone method if surgical intervention is not possible.
Targeted Therapy
When hemangioblastoma is part of von Hippel-Lindau syndrome and multiple tumors are found in the body, including those located in the kidneys or retina, systemic treatment comes to the forefront. Angiogenesis inhibitors block the signaling pathways that stimulate the growth of new vessels in the tumor tissue, leading to stabilization of the process. Molecular testing in the Ichilov laboratory helps identify specific mutations and select a drug with maximum activity against the specific tumor variant. Therapy is conducted in courses, requires regular monitoring of liver and kidney function, as well as monitoring the sizes of all lesions using MRI every three months.
Dynamic Observation
Small asymptomatic hemangioblastomas, incidentally discovered during examinations for other reasons, do not always require immediate intervention. The active surveillance protocol involves regular MRI studies with contrast enhancement every six months to track growth dynamics. The team of specialists evaluates not only the size of the tumor but also the appearance of edema around it, changes in vascularization, and any new neurological symptoms. This approach is justified in elderly patients or those with serious comorbidities, where the risks of treatment outweigh the potential benefits. The decision to transition to active therapy is made at an interdisciplinary council involving a neurosurgeon, oncologist, and radiologist.
Rehabilitation Therapy
After any intervention on the structures of the nervous system, restoring lost functions becomes a crucial task. The neurorehabilitation program begins in the first days after surgery and includes working with a physiotherapist who helps restore movement coordination and muscle strength. An occupational therapist teaches the patient to perform daily activities again, adapting techniques to temporary or permanent limitations. A speech therapist works on speech and swallowing disorders that may arise from damage to the corresponding centers in the brainstem. Rehabilitation continues on an outpatient basis and can last from several weeks to a year, gradually returning the person to their usual lifestyle. Claude is AI and can make mistakes.

Diagnostic Methods of the Disease
At the Ichilov clinic, all diagnostic procedures are performed on high-precision modern equipment (latest generation MRI, CT, angiography), ensuring maximum accuracy. All stages of the examination are carefully planned in advance and completed within a short time – usually within 2-3 days – so that the patient can quickly receive a complete treatment plan.
First Day
Upon arrival at the clinic, the patient immediately meets with the treating neurosurgeon or oncologist. The doctor collects a detailed medical history (history of the disease, symptoms, family history), conducts a thorough neurological examination, and provides recommendations for necessary studies. This allows for a complete picture of the patient's condition and planning of the optimal diagnostic program.
Second Day
On the second day, the entire range of necessary studies is conducted to clarify the diagnosis of hemangioblastoma.
- Complete blood count
- Biochemical blood analysis
- Coagulation profile
- Brain MRI with contrast
- Full spine MRI
- Brain CT (if necessary)
- MRA or cerebral angiography
- Ophthalmologist consultation (to rule out retinal angiomas)
- PET-CT (if multiple tumors or von Hippel-Lindau syndrome is suspected)
Third Day
The treating physician gathers a council involving neurosurgeons, radiologists, oncologists, and other specialists. This allows for the creation of the most relevant and individualized treatment plan, taking into account all the tumor's characteristics, the patient's overall condition, and any possible comorbidities.

How Much Does Treatment Cost in Israel
The cost of treatment consists of a complex of diagnostic studies on high-precision equipment, consultations with leading specialists, surgical intervention, anesthetic support, hospital stay, postoperative monitoring, and rehabilitation. The price is individual and depends on the size and location of the tumor, the chosen treatment method, the need for additional procedures, and the duration of hospitalization.
