Differential Diagnosis for Right Side Neck Swelling with Pain
Single Most Likely Diagnosis
- Lymphadenitis: This is an inflammation of the lymph nodes, often caused by a bacterial or viral infection. The symptoms of lymphadenitis, such as neck swelling and pain, are consistent with the presentation, making it a likely diagnosis.
Other Likely Diagnoses
- Tonsillitis: Infection or inflammation of the tonsils can cause referred pain and swelling in the neck, especially if the infection spreads to the lymph nodes.
- Dental Abscess: A dental infection can cause pain and swelling that radiates to the neck, particularly if the abscess is located in the lower teeth.
- Thyroiditis: Inflammation of the thyroid gland can cause neck pain and swelling, and while less common, it is a plausible diagnosis given the symptoms.
- Brachial Cyst: A benign cyst that develops in the neck, which can become inflamed and cause pain and swelling.
Do Not Miss Diagnoses
- Lymphoma: Although less common, lymphoma (cancer of the lymphatic system) can present with painless or painful lymph node swelling in the neck. Missing this diagnosis could have severe consequences.
- Tuberculosis: TB can cause lymph node swelling and pain, especially in the neck. Given its potential severity and the importance of early treatment, it's crucial not to miss this diagnosis.
- Carotid Artery Dissection: A tear in the carotid artery can cause neck pain and swelling, and it requires immediate medical attention to prevent stroke.
- Abscess (Deep Neck Abscess): A collection of pus in the deep tissues of the neck, which can be life-threatening if not promptly treated.
Rare Diagnoses
- Branchial Cleft Cyst: A congenital anomaly that can present as a lump in the neck, which may become infected and cause pain.
- Parotid Gland Tumors: Although rare, tumors of the parotid gland can cause swelling and pain in the neck and face.
- Actinomycosis: A rare bacterial infection that can cause chronic inflammation and abscesses in the neck.
- Kikuchi Disease: A rare condition characterized by lymph node swelling, usually in the neck, accompanied by fever and night sweats.
