Cerebellar Tumor Surgery: Types, Symptoms and Recovery

What Is Cerebellar Tumor Surgery?

Cerebellar tumor surgery removes a tumor from the cerebellum, the brain's center for balance. Surgeons reach it through a small opening low at the back of the skull. As a result, the operation relieves pressure and also reveals the exact tumor type.

In adults, the most common tumor here is a metastasis, spread from a cancer elsewhere. Other adult types include hemangioblastoma and pilocytic astrocytoma, which complete removal often cures.

Because space here is tight, even a benign tumor can cause trouble. So most tumors in this area need surgery, MedlinePlus notes.

Cerebellar Tumor Symptoms

Symptoms come from two sources: strain on the cerebellum and blocked brain fluid. According to MedlinePlus, they also tend to start early.

Questions at this stage

When to See a Doctor About Balance Problems or Headaches

Most cerebellar symptoms build up over weeks, so you usually have time to arrange a visit. However, rising pressure at the back of the skull can turn dangerous quickly.

These signs can mean pressure on the brainstem. So get help at the nearest hospital first, rather than waiting for a visit abroad.

Types of Cerebellar Tumors in Adults

Cerebellar tumors range from slow, benign growths to fast cancers. The type then decides whether surgery alone suffices or further treatment follows.

See also our overview of brain tumor treatment.

Metastases: The Most Common Type in Adults

Metastases start as a cancer elsewhere, most often in the lung, breast, kidney or skin. MedlinePlus notes that they far outnumber tumors that begin in the brain.

In the cerebellum, even a small one can block the fluid flow. So a single larger metastasis often comes out with surgery, while radiosurgery suits small ones. Our guide to treatment for metastatic brain tumors compares the options.

Hemangioblastoma and Von Hippel-Lindau Disease

A hemangioblastoma is a benign tumor full of small blood vessels, often with a fluid cyst.

Some people with it also have VHL disease, an inherited condition. According to MedlinePlus Genetics, VHL also causes growths in the eyes, kidneys and adrenal glands.

Pilocytic Astrocytoma

A pilocytic astrocytoma grows slowly and mostly affects children and young adults. Complete removal often cures it; our astrocytoma guide also covers other grades.

How Doctors Diagnose a Cerebellar Tumor

First, the neurosurgeon tests your balance, coordination, reflexes and strength. An MRI scan with contrast then shows the tumor best, as MedlinePlus also notes.

Further tests then depend on the likely tumor type:

• MRI of the brain with contrast: size, cysts and the tumor's link to the brainstem
• CT scan: in emergencies, and to show the bone of the skull
• MRI of the whole spine: spread through the spinal fluid, as with medulloblastoma
• Scans of the chest and abdomen: a hidden cancer behind a metastasis
• Eye exam and genetic tests: signs of VHL disease with a hemangioblastoma

Conditions That Can Look Like a Cerebellar Tumor

Other problems in the cerebellum can also resemble a tumor on scans. Examples include an abscess, a small stroke and, rarely, a fungal infection.

Tumors beside the cerebellum, such as an acoustic neuroma, cause unsteadiness too. So do brainstem tumors and a Chiari malformation, in which the lower cerebellum sits too low.

Cerebellar Tumor Treatment Options Compared

Surgery is the main treatment for most cerebellar tumors that cause symptoms. However, the tumor type, its size and your health shape the full plan.

At the consultation, Prof. Albayrak explains which option fits your tumor and why.

How Cerebellar Tumor Surgery Works

The operation aims to remove as much tumor as is safe, ideally all of it. To do so, Prof. Albayrak combines microsurgery with neuronavigation and nerve monitoring.

Before the Operation

First, a steroid medicine often reduces the swelling around the tumor. Sometimes a thin temporary drain also relieves trapped fluid.

With a suspected hemangioblastoma, doctors check for an adrenal tumor linked to VHL. MedlinePlus Genetics warns that such a tumor can turn dangerous during surgery.

The Suboccipital Craniotomy, Step by Step

First, under general anesthesia, you usually lie face down. The surgeon then opens a small window in the skull, low at the back of the head.

Neuronavigation works like GPS and shows the safest route to the tumor. Nerve monitoring, meanwhile, warns the team of any strain on the brainstem and nerves.

Under the microscope, the surgeon then separates the tumor from healthy tissue. Finally, the dura closes, the bone usually goes back, and the skin closes with stitches.

How Surgery Differs by Tumor Type

A hemangioblastoma bleeds easily, so the surgeon usually removes it in one piece. With a cyst, removing the small nodule often suffices, and the cyst then collapses.

For a metastasis, the surgeon aims for complete removal, and focused radiation often follows. With a medulloblastoma, radiotherapy to the brain and spine follows too.

What Happens to the Fluid Blockage

Once the tumor comes out, the brain's fluid then often flows freely again. A few people, however, still need an ETV or a shunt, as our hydrocephalus treatment guide explains.

Risks and Side Effects of Cerebellar Tumor Surgery

Surgery at the back of the skull carries real risks, because the brainstem lies close by. Serious problems are uncommon, but know them before you decide.

Possible problems include:

• Worse balance, dizziness or double vision for a while, from swelling
• Slurred speech or trouble swallowing for a while
• A spinal fluid leak, or fluid under the wound
• Infection or meningitis, which needs antibiotics
• Bleeding or swelling that needs a second operation (rare)
• Hydrocephalus that needs a drain or a shunt
• Blood clots and chest infections
• In children, a temporary loss of speech (cerebellar mutism)
• Tumor regrowth, especially when part of it stays

Early walking and physiotherapy also cut the risk of clots and chest infections.

Recovery and Rehabilitation After Cerebellar Tumor Surgery

Most people spend the first days in intensive care and then move to the ward. Physiotherapy starts early, and balance usually improves over weeks to months.

A Typical Timeline

Getting Your Balance Back

The cerebellum often adapts well, so steady practice matters more than rest. A physiotherapist first trains standing, walking and turning, then harder balance tasks.

Occupational therapy also helps with fine hand tasks, and speech therapy with speech or swallowing. The NHS lists the same kinds of support after a brain tumor.

• Walk every day, with a stick or a companion at first
• Rest when tired, since fatigue often lasts for weeks
• Avoid driving until your doctor and local rules allow it

Coming to Istanbul from the US, Canada, the UK or Europe

Cerebellar tumor surgery needs time for recovery, a tissue report and a safe flight home. So plan your trip around the operation, and keep the return date flexible.

How Long to Stay in Istanbul

First, add up the consultation, tests, operation and hospital stay, including intensive care. Then rest nearby until a final check of your wound and walking. Overall, many plans come to about two to three weeks in Istanbul.

When You Can Fly Home

After brain surgery, UK aviation guidance advises about 7 days before flying. Air left inside the skull can expand at altitude.

The US CDC also warns that flying after surgery raises the risk of blood clots. So your surgeon sets the date after a check-up. If your balance stays poor, book wheelchair help at the airport, too.

Further Treatment and Follow-Up at Home

Radiotherapy or chemotherapy often continues at home, so involve your local cancer team early. Before you leave, collect the discharge summary, the tissue report and copies of your scans. Then book your 3-month MRI with your local doctor.

UK drivers must tell the DVLA about a brain tumor. After a grade 1 cerebellar tumor, such as a hemangioblastoma, driving may resume on recovery. A medulloblastoma or a metastasis, however, brings longer breaks.

Prof. Dr. Serdar Baki Albayrak

Neurosurgeon · Full Professor of Neurosurgery

The cerebellum sits right behind the brainstem, which controls breathing and swallowing. For this reason, Prof. Albayrak plans each route with neuronavigation and monitors the nerves throughout.

He completed his neurosurgery training at Istanbul University in 2004. He then took clinical fellowships at the University of Helsinki and Harvard Medical School. At Harvard, he trained at Brigham and Women's Hospital.
