A carotid body tumor (also called a chemodectoma or paraganglioma) is a growth on the side of your neck in the area where the carotid artery splits off into smaller blood vessels that carry blood to your brain.
The perivisceral lymph nodes are located in the central compartment of the neck, defined as level VI, which is delimited laterally by the common carotid arteries, inferiorly by the jugular notch, and superiorly by the hyoid bone2, and that coincides with the muscular triangle, described in the anatomy compendiums.
At first a carotid body tumor may not present any symptoms, but it can usually be felt as a slow-growing, painless mass on the side of a person’s neck. As the tumor gets bigger, over the course of several years, it may start to cause symptoms that include: Difficulty swallowing. High blood pressure or heart …
Along with atherosclerosis, there are other less common conditions that also can affect the carotid arteries, including: Aneurysms or swelling of the artery. Carotid artery dissections, where the wall of the artery splits.
The carotid arteries are two large blood vessels that supply oxygenated blood to the large, front part of the brain. This is where thinking, speech, personality, and sensory and motor functions reside. You can feel your pulse in the carotid arteries on each side of your neck, right below the angle of the jaw line.
The most common lumps or swellings are enlarged lymph nodes. These can be caused by bacterial or viral infections, cancer (malignancy), or other rare causes. Swollen salivary glands under the jaw may be caused by infection or cancer. Lumps in the muscles of the neck are caused by injury or torticollis.
- Painless swelling of lymph nodes in your neck, armpits or groin.
- Persistent fatigue.
- Night sweats.
- Shortness of breath.
- Unexplained weight loss.
- Itchy skin.
When to see a doctor See your doctor if you’re concerned or if your swollen lymph nodes: Have appeared for no apparent reason. Continue to enlarge or have been present for two to four weeks. Feel hard or rubbery, or don’t move when you push on them.
Both common carotid arteries run within the carotid sheath until they bifurcate into the internal and external carotid arteries at the level of the upper border of the thyroid cartilage.
They are slow-growing tumors that can remain asymptomatic for many years. The doubling time (TD) of carotid body tumors (CBTs), as estimated by Jansen et al using sequential imaging, was 7.13 years with a median growth rate of 0.83 mm/year.
We report a case of carotid body tumor in a 42-year-old female, who presented with painless, pulsatile, gradually progressive lateral neck swelling. The diagnosis is suspected on the basis of history, clinical and radiological examination findings and a successful surgical excision of the tumor is performed.
The incidence of carotid body tumors (CBTs) is less than 1 in 30000. CBTs represent more than half of neck paragangliomas (PGLs), yet still a very rare cause of neck lumps. Like other paragangliomas, CBTs originate from the neural crest. The most common site is the carotid body.
Carotidynia is a pain that you feel in your neck or face. It is linked with physical changes that can happen in a carotid artery in your neck. Your neck may feel tender in the area of the artery. The pain often goes up the neck to the jaw, ear, or forehead.
One of the common causes of pain in the neck is soreness and tenderness of one or both carotid arteries and is related to overdistention, relaxation, and increased pulsation in this vessel. The syndrome of vascular neck pain is closely related to the various forms of extracranial vascular headache.
An extracranial carotid artery aneurysm is a bulging or ballooning in the wall of the carotid artery in the neck.
- Sudden numbness or weakness in the face or limbs, often on only one side of the body.
- Sudden trouble speaking and understanding.
- Sudden trouble seeing in one or both eyes.
- Sudden dizziness or loss of balance.
- Sudden, severe headache with no known cause.
The carotid arteries are major blood vessels in the neck that supply blood to the brain, neck, and face. There are two carotid arteries, one on the right and one on the left. In the neck, each carotid artery branches into two divisions: The internal carotid artery supplies blood to the brain.
- Chest pain.
- Shortness of breath.
- Heart palpitations.
- Weakness or dizziness.
Lymph nodes often swell in one location when a problem such as an injury, infection, or tumor develops in or near the lymph node. Which lymph nodes are swollen can help identify the problem. The glands on either side of the neck, under the jaw, or behind the ears commonly swell when you have a cold or sore throat.
What does a cancerous lymph node feel like? Cancerous lymph nodes can occur anywhere on the neck and are typically described as firm, painless, and sometimes may be immovable.
A lump on your neck could be anything from a minor infection to a serious condition. Most moveable lumps aren’t serious. In general, if the lump is soft and goes away on its own, it’s probably nothing to worry about. A neck lump that persists, grows, or hurts could be a sign of infection or other illness.
- Hodgkin’s lymphoma.
- Cat scratch fever.
Most types of lymphoma can’t be diagnosed by a blood test. However, blood tests can help your medical team find out how lymphoma and its treatment are affecting your body. They can also be used to find out more about your general health.
Lymphomas can start anywhere in the body where lymph tissue is found. The major sites of lymph tissue are: Lymph nodes: Lymph nodes are bean-sized collections of lymphocytes and other immune system cells throughout the body, including inside the chest, abdomen, and pelvis.
People can check whether their lymph nodes are swollen by gently pressing around the area, such as the side of the neck. Swollen lymph nodes will feel like soft, round bumps, and they may be the size of a pea or a grape. They might be tender to the touch, which indicates inflammation.
Lymph nodes can always be felt in the neck and groin. They are about the size of a bean. They never go away.
What causes swollen lymph nodes? The most common cause of lymph node swelling in your neck is an upper respiratory infection, which can take 10 to 14 days to resolve completely. As soon as you start feeling better, the swelling should go down as well, though it may take a few weeks longer to go away completely.
The carotid triangle includes the common carotid artery and its bifurcation into the external carotid artery (ECA) and internal carotid artery (ICA). It usually contains the superior thyroid, lingual, facial, occipital, and ascending pharyngeal arteries.
The vagus nerve usually lies in a posterior lateral position within the carotid sheath but occasionally may spiral anteriorly, particularly in the lower end of the incision.
A muscle flap made of the upper portion of the pectoralis major is used to protect the carotid artery.
See your doctor and/or an ENT (ear, nose, and throat) specialist, or otolaryngologist, if the lump in your neck lasts longer than two to three weeks. This is a persistent neck mass, which means that the lump has not gone away.
The actual size of the tumors may vary greatly. Some have reported tumors as large as 10 cm. Paragangliomas that are found in difficult to access locations such as jugulotympanic paragangliomas more often will be fragmented and histologic features may be difficult to decipher.
Taking your carotid pulse Your carotid pulse can be taken on either side of your neck. Put the tip of your index and long finger in the groove of your neck along your windpipe to feel the pulse in your carotid artery.
Carotid body tumor, also known as a chemodectoma or carotid body paraganglioma, is a highly vascular glomus tumor that arises from the paraganglion cells of the carotid body. It is located at the carotid bifurcation with characteristic splaying of the ICA and ECA.
Embolization involves using a type of glue or special particles to stop the blood flow. The surgical removal (also called surgical resection) of the tumor takes place after the embolization. The neurosurgeon makes an incision in the neck and performs this open surgical procedure to remove the tumor.
With a cervical artery dissection, the neck pain is unusual, persistent, and often accompanied by a severe headache, says Dr. Rost. The neck pain from a carotid artery tear often spreads along the side of the neck and up toward the outer corner of the eye.
6 Inflammation, degeneration, and increased pressure within the venous system could also be possible causes of venous aneurysm in the neck. 5 Venous aneurysms in the neck usually have a benign clinical course and may present as cervical swelling, pain and tenderness in the neck.
