Hemangioblastoma

What it is

From: Orphanet

A rare benign, highly vascularized tumor characterized by various symptoms depending on the location. They typically occur in the brain (typically cerebellum, in addition to brainstem, cerebrum) and spinal cord, and predominantly affect the central nervous system. However they can also be found in peripheral nerves, bone and soft tissue, liver, lung, pancreas, kidney, intestines, and skin in a lesser extent. They most commonly occur sporadically or in association with von Hippel-Lindau syndrome. Patients having cerebellar tumors often present with headaches, nausea, vomiting, and signs of increased intracranial pressure, whereas patients having brainstem tumors develop motor and sensory deficits, ataxia, and potentially fatal hemorrhages. Hemangioblastomas located in spinal cord may result in localized pain, motor weakness, sensory disturbances, and bowel or bladder dysfunction. Patients having optic nerve hemangioblastoma were also reported of either being asymptomatic or manifest vision loss, proptosis, and pain.

Reported clinical features and what the terms mean

The following findings are associated with this condition in Orphanet. They are not a checklist for diagnosing yourself, and they do not all occur in every affected person. Some are examination, imaging or laboratory findings that cannot be recognised at home.

The frequency labels describe how often a finding was reported among people with the condition in the source. They do not give the chance that a person with that symptom has the condition. Definitions below reproduce HPO terminology; they explain the term, not the likely severity in an individual.

Cerebellar edema · Very frequent (99-80%)

Swelling from fluid accumulation (serous fluid infiltration into the interstitial space) in the cerebellum.

Cerebellar hemangioblastoma · Very frequent (99-80%)

A hemangioblastoma of the cerebellum.

Headache · Very frequent (99-80%)

Cephalgia, or pain sensed in various parts of the head, not confined to the area of distribution of any nerve.

Hemangioblastoma · Obligate (100%)

A hemangioblastoma is a benign vascular neoplasm that arises almost exclusively in the central nervous system. Hemangioblastomas consist of a tightly packed cluster of small blood vessels forming a mass of up to 1 or 2 cm in diameter.

Intracranial cystic lesion · Very frequent (99-80%)

A cystic lesion originating within the brain.

Nausea and vomiting · Very frequent (99-80%)

Nausea is a commonly encountered symptom that has been defined as an unpleasant painless subjective feeling that one will imminently vomit. Vomiting has been defined as the forceful expulsion of the contents of the stomach, duodenum, or jejunum through the oral cavity. While nausea and vomiting are often thought to exist on a temporal continuum, this is not always the case. There are situations when severe nausea may be present without emesis and less frequently, when emesis may be present without preceding nausea.

Retinal capillary hemangioma · Very frequent (99-80%)

A benign vascular tumor of the retina without any neoplastic characteristics.

Vertigo · Very frequent (99-80%)

An abnormal sensation of spinning while the body is actually stationary.

Dysesthesia · Frequent (79-30%)

Painful sensations elicited by a nonpainful cutaneous stimulus such as a light touch or gentle stroking over affected areas of the body. Sometimes referred to as hyperpathia or hyperalgesia. Often perceived as an intense burning, dyesthesias may outlast the stimulus by several seconds.

Hypoactive bowel sounds · Frequent (79-30%)

An decreased amount of bowel sounds.

Lower limb muscle weakness · Frequent (79-30%)

Weakness of the muscles of the legs.

Neurogenic bladder · Frequent (79-30%)

A type of bladder dysfunction caused by neurologic damage. Neurogenic bladder can be flaccid or spastic. Common manifestatios of neurogenic bladder are overflow incontinence, frequency, urgency, urge incontinence, and retention.

Spinal hemangioblastoma · Frequent (79-30%)

A hemangioblastoma of the spinal cord.

Trigeminal neuralgia · Frequent (79-30%)

A neuropathic disorder characterized by episodes of intense pain in the face, originating from the trigeminal nerve. One, two, or all three branches of the nerve may be affected.

Which doctor should you see?

The suggested department for discussing Hemangioblastoma is Oncology, with a oncologist and relevant organ specialist as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.

Additional services that may be relevant, depending on the findings, include: Relevant organ specialist / Surgical Oncology as indicated.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• Has the exact tumour type been confirmed, and is staging relevant?
• What is the goal of each proposed treatment option?
• How will side effects, daily function and supportive care be addressed?

Treatment discussions and follow-up

The material gathered for this draft does not provide a complete condition-specific treatment pathway for Hemangioblastoma. That gap does not mean that treatment is unavailable. A clinician needs to establish the diagnosis and review current guidance before recommending medicines, procedures, rehabilitation or other support.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

The collected references do not establish a complete prevention or long-term outlook section for this entry. Missing information should not be interpreted as proof that prevention is impossible or that a particular outcome is inevitable. Ask what is known for the exact subtype, stage and personal circumstances, and which uncertainties remain.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
