Differential Diagnosis for Swollen Glands in the Neck
Single Most Likely Diagnosis
- Viral Pharyngitis: This is often the most common cause of swollen glands in the neck, typically resulting from a viral infection such as mononucleosis or the common cold. The swollen glands are usually a reactive lymphadenopathy, which is the body's response to the infection.
Other Likely Diagnoses
- Bacterial Pharyngitis: Caused by bacteria like Streptococcus pyogenes, this condition can also lead to swollen lymph nodes in the neck as the body fights the infection.
- Tonsillitis: Inflammation of the tonsils, often due to infection, can cause the lymph nodes in the neck to become swollen.
- Dental Infections: Abscesses or infections in the teeth or gums can lead to swollen lymph nodes in the neck due to the spread of infection.
- Mononucleosis (Mono): Caused by the Epstein-Barr virus, mono can lead to significant lymphadenopathy, including swollen glands in the neck.
Do Not Miss Diagnoses
- Lymphoma: Although less common, lymphoma (both Hodgkin and non-Hodgkin) can present with swollen lymph nodes in the neck and is critical to diagnose early for effective treatment.
- Tuberculosis (TB): TB can cause lymphadenopathy, particularly in the neck, and is crucial to diagnose due to its public health implications and the need for specific treatment.
- HIV Infection: Acute HIV infection can present with lymphadenopathy, among other symptoms, and early diagnosis is vital for managing the disease.
- Thyroid Cancer: Certain types of thyroid cancer can cause lymphadenopathy in the neck, making it essential to consider in the differential diagnosis.
Rare Diagnoses
- Sarcoidosis: A condition that can cause inflammation in various parts of the body, including the lymph nodes, leading to swollen glands.
- Cat-Scratch Disease: Caused by the bacterium Bartonella henselae, this disease can result from a cat scratch or bite and lead to swollen lymph nodes.
- Toxoplasmosis: Infection with the Toxoplasma gondii parasite can cause lymphadenopathy, although it is more commonly associated with other symptoms.
- Kawasaki Disease: A rare condition in children that can cause lymphadenopathy, among other symptoms like fever and rash.
