They may also experience systemic symptoms, such as: People with a malignant lymph node may notice that the node feels hard or rubbery. These include being aged 40 years or older and being assigned male at birth. metastases, or the spread of an existing cancerĬertain risk factors make a person more likely to have a malignant lymph problem, such as lymphoma.Much less commonly, swollen lymph nodes can also indicate a malignancy, or cancer, including: Immune disorders that can cause swollen lymph glands include: InfectionsĮxamples of infections that can cause swollen lymph nodes can include:Ĭat scratch fever, which is also called cat scratch disease, can cause localized lymph node swelling in the area near the cat scratch. The following sections discuss the possible causes of swollen lymph nodes in more detail. When more than one region swells, this is called generalized lymphadenopathy, and it usually signifies a systemic, or body-wide, disease that may require medical attention. Most people have localized lymphadenopathy, in which only the lymph nodes in one particular area of the body swell up. It is important to contact a doctor to discuss any possible side effects of medications. These conditions can include:Ĭertain medications can also cause swelling. Many different conditions cause the lymph nodes to swell, particularly the nodes in the head and neck. For example, an ear infection may cause swollen lymph nodes near the ear, while someone with an upper respiratory tract infection may notice swollen lymph nodes in their neck. The location of the swelling often relates to the affected area. The swelling occurs as a result of immune cell activity in the lymph nodes. The lymph nodes may swell when a person has an infection. Lymph nodes also contain immune cells that help fight infection by attacking the germs that the body’s lymph fluid has collected. The lymph nodes filter the fluid and release it back into the bloodstream together with salts and proteins. While doing so, it collects and traps harmful matter, such as bacteria, viruses, and bodily waste products. Lymph fluid flows in and out of the lymph nodes throughout the body before finally making its way back to the chest. The main lymph nodes that people may see or feel are found: The human body has hundreds of lymph nodes. The lymph nodes collect and filter fluids, waste materials, and harmful germs. Other imaging tests and clinical history can help in some cases.Share on Pinterest Jovo Jovanovic/Stocksy United It is often not possible to tell the cause of the lymph node enlargement without a biopsy. Enlarged lymph nodes can also occur because of spread of cancer, infections, inflammatory conditions or more generalized illnesses. When lymph nodes are markedly enlarged and matted, than lymphoma becomes the main consideration. These infections will often be apparent to the clinical doctor.Įnlarged lymph nodes in the pelvis on CT can therefore have many causes. Ulcers or infections of the skin result in enlarged lymph nodes on CT. Infections like Syphilis, flu, fungus can cause more generalized lymph node enlargement.More systemic conditions will result in more generalized enlarged lymph nodes not isolated to the pelvis.Įnlarged lymph nodes in the pelvis are common when there are infections or inflammatory conditions of the legs and feet. Autoimmune conditions like lupus or arthritis like rheumatoid can cause lymphadenopathy. Often there will be a history of cancer or associated findings.Įnlarged lymph nodes in the pelvis on CT can be seen with systemic infections like HIV/AIDS which can cause lymphadenopathy in the body. Many types of cancer produce enlarged lymph nodes in the pelvis on CT but some of the more common ones are prostate cancer, gynecological cancer, and cancers of the extremities. Spread of cancer to the lymph nodes in the pelvis is another cause of enlarged lymph nodes. Lymphoma staging often involves imaging the body with CT or PET scan. Lymphoma is a blood cancer and can be limited to the nodes or involve structures outside the lymph nodes. Multiple markedly enlarged lymph nodes in the pelvis that are greater than say 2 centimeters and matted raise concern for something like lymphoma. Unfortunately, distinguishing those lymph nodes that are from benign conditions and cancer may not be possible without biopsy. Enlarged lymph nodes in the pelvis are those which are abnormally shaped or larger than typical. Enlarged lymph nodes on CT in the pelvis can be present because of infections, inflammatory conditions, cancer, or even medications.
