Aortic and Carotid Artery Neuroendocrine Tumors in Cats Understanding Feline Aortic and Carotid Artery Neuroendocrine Tumors

Aortic and Carotid Artery Neuroendocrine Tumors in Cats

Neuroendocrine tumors (NETs) are among the rarest forms of tumor that cats can get. Here, we will talk more about this condition.

Cats are known to develop various types of tumors, and neuroendocrine tumors (NETs) are among the rarest. These tumors arise from the cells that produce hormones and can occur in various parts of the body, including the aortic and carotid arteries. Aortic and carotid artery neuroendocrine tumors in cats can be difficult to diagnose and treat because of their location and symptoms. 

In this article, we will delve into the causes, symptoms, diagnosis, and treatment options for aortic and carotid artery neuroendocrine tumors in cats. We will also explore the prognosis for this type of tumor and what pet owners can do to help their furry friends through the process.


The particular cause of aortic and carotid artery neuroendocrine tumors in cats is not well understood. However, there are certain factors that may heighten the possibility of developing these types of tumors, including:

  • Genetic predisposition: Siamese and Abyssinian cat breeds may be more prone to acquiring specific types of tumors, including NETs.

  • Age: Tumors, including NETs, are more likely to form in older cats.

  • Hormonal imbalances: Neuroendocrine tumors may form as a result of hormonal abnormalities.

  • Environmental toxin exposure: Exposure to particular chemicals or toxins may raise the risk of getting malignancies.

  • Infections: Aortic and carotid artery neuroendocrine tumors in cats may potentially be influenced by infections or chronic inflammation.

Diagnosis of Chemodectoma in Cats

Due to their location and symptoms, aortic and carotid artery neuroendocrine tumors in cats can be difficult to diagnose. However, a veterinarian can confirm the existence of these tumors using a number of diagnostic techniques, such as:

  • Physical examination: A veterinarian may feel a lump in the neck or a swollen artery during a physical examination.

  • Imaging procedures: Imaging procedures, including CT scans, X-rays, and ultrasounds, can help visualize the tumor and pinpoint its precise position.

  • Biopsy: The most conclusive technique to diagnose a neuroendocrine tumor is through a biopsy. To identify the type of tumor, a small tissue sample is removed from the growth and examined under a microscope.

  • Blood tests: Blood tests can be used to assess the health of the cat generally and look for any anomalies, such as hormonal imbalances.

  • Fine-needle aspiration: A fine needle is used to extract a small amount of tissue from the tumor, which can then be examined under a microscope to determine the type of tumor.

Neuroendocrine Tumors in Cats Symptoms

The symptoms of aortic and carotid artery neuroendocrine tumors in cats differ depending on where the tumor is located and how large it is. The following are some typical signs that aortic body tumor cats may show:

  • Panting or difficulty breathing: As the tumor enlarges, it may obstruct the cat's airway, making it challenging for it to breathe normally.

  • Inflammation of the neck: A carotid artery tumor may result in inflamed neck tissue.

  • Loss of appetite or weight loss: Discomfort or other symptoms in cats with tumors may cause them to lose their appetite or lose weight.

  • Lethargy or weakness: Due to the stress a tumor places on the cat's body, it might result in lethargy or weakness.

  • Difficulty swallowing: A tumor in the aortic artery may make it difficult for the cat to swallow.

  • Seizures: In some cases, a neuroendocrine tumor can cause seizures or other neurological symptoms.

Treatment and Management Options for Carotid Body Tumor Cats

The size, location, and general health of the cat all have a role in the course of chemodectoma treatment. The tumor may need to be surgically removed in some circumstances, while the veterinarian may advise a mix of treatments, such as:

  • Chemotherapy: For cats with advanced or metastatic cancers, chemotherapy may be advised.

  • Radiation therapy: Radiation therapy may be advised for cats with inoperable tumors or those who are not responding to other therapies.

  • Medications: Drugs might be provided to treat symptoms like pain or inflammation. Prednisolone or Onsior may be prescribed according to the cat’s peculiar symptoms.

  • Supportive treatment: Supportive care may be advised to assist the cat in managing their symptoms and enhance their quality of life. Examples include dietary support or oxygen therapy.

  • Periodic examinations: To track the tumor's development and modify treatment as necessary, routine examinations and imaging tests may be required.

Prevention Tips

Currently, there are no known prevention tips for aortic and carotid artery neuroendocrine tumors in cats. However, there are steps pet owners can take to keep their cats healthy and reduce their risk of developing tumors:

  • Schedule frequent visits: Regular check-ups with a veterinarian can help detect any health issues on time, including tumors.

  • Maintain a healthy diet: Feeding your cat a balanced and nutritious diet can help support its general health and immune system.

  • Minimize exposure to environmental toxins: Limiting your cat's exposure to environmental toxins and chemicals may help reduce their possibility of developing tumors.

  • Keep your cat at a healthy weight: Obesity may heighten the risk of developing health issues, including tumors.

  • Consider genetic testing: If you have a breed of cat that is predisposed to developing certain types of tumors, genetic testing may help identify any potential health risks.

While there are no guaranteed ways to prevent tumors in cats entirely, taking these steps can help support your cat's overall health and reduce its risk of developing health issues.
