Lymph Node Inflammation in CatsWritten By hannah hollingerPublished: 10/05/2016Updated: 05/14/2021What is Lymph Node Inflammation?The production of too many immune cells at once is what causes the lymphadenopathy. Either a solitary nodule can be effected, or a group of nodules. When this occurs in younger cats, it is generally due to an infectious disease. Swollen lymph nodes are a common finding in many sick cats. Infections and other complications signalled by inflamed lymph nodes need to be treated by a veterinarian as soon as possible for the best results.Lymph nodes are ducts within the body that are used to collect fluid and return it to the bloodstream. Inside the lymph nodes, lymphocytes (white blood cells) destroy bacteria, fungi, viruses, and cancer cells. When the body faces infection, the lymph nodes located closest to the infection will swell or enlarge. This is referred to as lymphadenopathy.Youtube PlayLymph Node Inflammation Average CostFrom 473 quotes ranging from $200 - $3,000Average Cost$850Protect yourself and your pet.

Symptoms of Lymph Node Inflammation in CatsAs lymph nodes swell from many different types of infections all over the body, various symptoms can occur. Below are the most common symptoms associated with lymphadenopathy.

• Swollen lymph nodes
• Tender or painful lymph nodes
• Fever
• Lethargy
• Vomiting
• Diarrhea
• Weight loss
• Loss of appetite
• Difficulty swallowing
• Mouth abscess
• High temperature
• Limping
• Dull hair coat

Causes of Lymph Node Inflammation in CatsGenerally, the cause of swollen lymph nodes has to do with a nearby issue in the body. These issues can range from minor to life-threatening and should be evaluated by a veterinarian. Causes are as follows:

• Bacterial infection
• Fungal infection
• Viral infection
• Parasitic disease
• Allergies
• Reactive Lymphoid Hyperplasia (benign lymph node swelling)
• Cancer of the lymph nodes or nearby organs
• Neoplastic Infiltration (meningitis caused by cancer cells)

Diagnosis of Lymph Node Inflammation in CatsThe first thing that a veterinarian will need from you is your cat's extensive medical history. This can give clues to underlying problems that may have developed to cause the swelling. A physical examination of the cat will be completed to try and locate the affected lymph nodes by feeling key areas of the body. Often this will include the submandibular (where the jaw meets the neck), the axillary (armpit of the front legs), the prescapular (where the front leg joins the shoulder) and the popliteal (on the rear legs opposite of the knee) areas. If there is any pain in these locations, that is an indication of swollen lymph nodes.  The vet will rule out all possible harmless syndromes by assessing all symptoms. Blood work will be done to get an overall picture on the cat's health. A complete blood count will show how many blood cells are present and indicate if cancer is the cause. A biochemical profile will show other substances in the blood. Urinalysis can help detect bacteria that may be causing infection. A lymph node biopsy to collect samples for microscopic examination may be needed if cancer is suspected.  X-rays and ultrasounds can be used to detect tumors or other abnormalities on the lymph nodes. When any lymphadenopathy is present, Feline Leukemia Virus and Feline Immunodeficiency Virus should be tested for. A fecal parasitological exam may be needed if parasites are suspected. The vet may recommend more extensive testing until a cause has been identified.Treatment of Lymph Node Inflammation in CatsTo restore lymph nodes to their normal size, the underlying condition that is causing the inflammation needs to be treated. There are a number of different treatments depending on which ailment the cat is suffering from. Bacterial Infection  The corresponding antibiotic will be prescribed to eliminate a bacterial infection. Antibiotics are often prescribed for 2-4 weeks. Fungal Infection  Antifungal medication, shampoo, or cream will be prescribed to eradicate a fungal infection affecting the cat.  Allergies  In the case of allergies, tests or the process of elimination will be used to identify the allergen. Once identified, the allergen will be removed from the cat’s environment or diet. Viral Infections  Most viral infections can only be treated symptomatically. The cat may need to be hospitalized for supportive care while fighting a viral infection. Intravenous fluids may be administered to keep the cat hydrated. Other care may be administered to keep the cat as comfortable as possible. Cancer  Cancer of the lymph nodes is very serious and needs to be treated aggressively. There are three main ways to treat cancer of the lymph nodes.

• Surgical Removal: This may be possible if the cancer has not spread out of the lymph nodes. If the cat is in good condition, a general anesthetic will be administered and surgery will be performed. Depending on the location of the lymph nodes, the surgery can vary in its overall risk. At home care will be needed upon discharge.
• Chemotherapy: This treatment can slow the progress of lymph node cancer in cats. It should be noted that cats are not treated the same way as humans. If the chemotherapy will drastically reduce the cat's quality of life, it will not be used.
• Radiation Therapy: This treatment is often used in combination with surgery. It can focus on the microscopic occurrences of cancer that cannot be surgically removed.

Recovery of Lymph Node Inflammation in CatsOnce your cat is home, take care to administer all prescriptions exactly as requested. This can help ensure all infections are properly treated. If symptoms are not going away, further treatment and tests may be necessary to find the root of the issue. A check-up appointment will be needed to gauge if lymph node swelling has gone down.  Once an infection has cleared out of the cat’s system, the lymph nodes should return to their normal size. If the cat has undergone surgery, extra care should be given to keep the incision clean and decrease all stress inducers during the healing process. It should be noted that in cases of lymph node cancer, prognosis is not great, with the maximum survival being about two years.Lymph Node Inflammation Average CostFrom 473 quotes ranging from $200 - $3,000Average Cost$850Protect yourself and your pet.

My pet has the following symptoms:Cat Flu- Sneezing, Runny Nose, Trouble Breathing, Swollen Eyes, Swollen LympnoidI have an 11 month old barn cat. He had developed what looks like cat flu. He was sneezing, runny nose and eyes. He took off for 3 days and came back with his one eye swollen and looked like full of mucus. I cleaned with warm cloth and gave medicated eye droos. I have been giving him water with electrolytes 3 times a day to keep him hydrated, and have been trying to give him nutrical but he fights it as he seems to have a hard time swallowing. I noticed today that he has a swollen lymph node on his neck. He will drink water on his own, but he has yet to eat anything.Aug. 3, 2020Answered by Dr. Michele K. DVM10 RecommendationsThank you for your question. That cat sounds quite sick, and it would probably be best to have them seen by a veterinarian. It may need antibiotic therapy or other medications. Once a veterinarian is able to look at the cat, see what might be going on, and get a treatment plan, you may be able to help keep the cat healthy. I hope that all goes well for the cat.Aug. 3, 2020Was this question and answer helpful?

My pet has the following symptoms:Swollen Lymph Nodes Back LegsMy cat is only indoors and is a real odd ball. The last inch of his tail is broken at an angle and one of his canine teeth grew in straight forward. Otherwise he's been the picture of health. I recently noticed the lymph nodes behind his back "knees" were really swollen and I have a vet appointment, but with limited contact with a vet these days I'm trying to prepare myself for some things. He's not showing any other signs of pain or discomfort, he's eating/drinking normally. I can't tell of any other swelling going on, though, so with it localized there on his legs I'm wondering what it couldbeJuly 28, 2020Answered by Dr. Michele K. DVM10 RecommendationsThank you for your question. Swollen lymph nodes can happen with infection or lymphoma. If there are more than one swollen lymph node, we worry more. Your veterinarian will be able to take samples at your appointment, and see if you have a concern for cancer or if it is infection. They will be able to discuss treatment with you as well. I hope that all goes well for your cat.July 28, 2020Was this question and answer helpful?
