Patient ReportsCirsoid Aneurysm: Diagnosis and Treatment
Written by Medicover Team and Medically Reviewed by Dr Sudharsan Reddy Yalamuru , Vascular Endovascular Surgeon
Table of Contents
Cirsoid aneurysms are characterised by an abnormal tangle of blood vessels where arterial blood flows directly into the venous system, bypassing capillaries. Predominantly occurring in the scalp, these aneurysms can lead to a pulsatile mass, visible swelling, and increased vascularity.
What are the Causes of Cirsoid Aneurysms?
The aetiology of cirsoid aneurysms is multifaceted, with both congenital and acquired factors contributing to their development.
Congenital Factors
Some individuals are born with arteriovenous malformations (AVMs) that predispose them to developing cirsoid aneurysms. These congenital AVMs result from incomplete embryonic development of the vascular system, leading to direct arterial-to-venous connections.
Acquired Factors
- Trauma: Head injuries, particularly those affecting the scalp, can instigate the formation of a cirsoid aneurysm. This trauma can lead to the rupture of small blood vessels, forming abnormal connections as they heal.
- Surgical Interventions: Previous surgeries involving scalp incisions may inadvertently contribute to the development of cirsoid aneurysms.
- Infections: Rarely, severe infections affecting scalp tissues can trigger vascular changes leading to aneurysm formation.
What are the Symptoms of Cirsoid Aneurysms?
The symptoms of cirsoid aneurysms can vary based on the size and location of the malformation. Common symptoms include:
- Pulsatile Mass: A noticeable, throbbing mass on the scalp, often accompanied by a bruit (a whooshing sound heard with a stethoscope).
- Swelling: Localized swelling on the scalp that may increase in size over time.
- Pain or Tenderness: The affected area may become painful or tender to touch, particularly if inflammation occurs.
- Bleeding: Given the superficial location of many cirsoid aneurysms, there is a risk of spontaneous bleeding or bleeding following minor trauma.
When to See a Doctor for Cirsoid Aneurysms?
If you notice a pulsating swelling on the scalp, persistent headaches, bleeding from a scalp lesion, visible enlarged blood vessels, or symptoms that worsen over time, consult a Vascular Endovascular Surgeon. Early diagnosis and treatment can help prevent complications such as excessive bleeding, pain, and cosmetic concerns.
- If you develop a pulsating lump or swelling on the scalp.
- If you experience persistent headaches or scalp pain associated with the swelling.
- If the affected area bleeds spontaneously or after minor trauma.
- If you notice enlarged, twisted, or prominent blood vessels on the scalp.
- If the swelling increases in size or becomes painful.
- If you experience dizziness, ringing in the ears, or cosmetic changes due to the lesion.
- If you have a history of scalp injury followed by the development of abnormal blood vessels.
- If your symptoms persist or worsen, consult a Vascular Endovascular Surgeon for a comprehensive evaluation, imaging studies, and a personalized treatment plan.

How are Cirsoid Aneurysms Diagnosed?
Accurate diagnosis of a cirsoid aneurysm is crucial for effective treatment planning. Several diagnostic modalities are employed to assess the condition.
Physical Examination
A thorough physical examination often reveals the characteristic pulsatile mass and audible bruit. The clinician may also assess for any neurological deficits or signs of increased intracranial pressure if cerebral involvement is suspected.
Imaging Studies
- Ultrasonography: Doppler Ultrasound can help visualize blood flow patterns, confirming the presence of arteriovenous connections.
- CT Angiography (CTA): Offers detailed images of blood vessels, aiding in the assessment of the aneurysm's size and extent.
- Magnetic Resonance Angiography (MRA): Provides high-resolution images of vascular structures without exposing patients to radiation.
- Digital Subtraction Angiography (DSA): Considered the gold standard for vascular imaging, DSA offers precise details about vascular architecture and is often used in pre-surgical planning.
How are Cirsoid Aneurysms Treated?
The treatment of cirsoid aneurysms is tailored to the individual based on the aneurysm's characteristics and the patient's overall health. The primary goals are to relieve symptoms, prevent complications, and eliminate the aneurysm.
Surgical Intervention
- Ligation and Excision: Direct surgical removal of the aneurysm involves ligating feeding vessels and excising the affected area. This method is often preferred for accessible, well-defined aneurysms.
- Embolization: This minimally invasive endovascular technique involves inserting embolic agents into the feeding arteries to block blood flow. It can be used alone or together with surgery.
- Stereotactic Radiosurgery: For aneurysms not suitable for conventional surgery, focused radiation therapy may be used to promote gradual closure of abnormal blood vessels.
Non-Surgical Management
In selected cases, conservative management may be appropriate, particularly if the aneurysm is asymptomatic or poses a low risk of complications. Regular monitoring and avoiding trauma to the scalp are generally recommended.

What are the Latest Advancements in Cirsoid Aneurysm Treatment?
Recent advances in imaging and interventional radiology have significantly improved the diagnosis and treatment of cirsoid aneurysms. Innovations such as three-dimensional rotational angiography and advanced embolic materials provide greater treatment precision and improved outcomes.
A multidisciplinary approach involving vascular surgery, endovascular specialists, neurosurgeons, and interventional radiologists has further enhanced patient care. Early diagnosis and timely treatment remain essential for preventing complications and achieving the best possible long-term results.
