Differential Diagnosis for 2-Day Right Side Swollen Glands
- Single most likely diagnosis
- Viral pharyngitis: The patient's symptoms of swollen glands and pain upon swallowing, without a sore throat, could be indicative of a viral infection affecting the lymph nodes in the neck, which is a common and likely cause.
- Other Likely diagnoses
- Bacterial pharyngitis: Although the throat is not sore, bacterial infections like streptococcal pharyngitis can cause swollen lymph nodes and discomfort, making it a plausible diagnosis.
- Mononucleosis: Caused by the Epstein-Barr virus, this condition often presents with swollen lymph nodes, particularly in the neck, and can lead to discomfort when swallowing.
- Reactive lymphadenitis: This is an inflammatory reaction in the lymph nodes, often in response to an infection elsewhere in the body, which could explain the swollen and painful glands.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Malignancy (lymphoma): Although rare, lymphoma can present with swollen lymph nodes, and it is crucial to consider this diagnosis to ensure timely treatment if present.
- Abscess (peritonsillar or retropharyngeal): These can cause severe pain and swelling, and if not promptly treated, can lead to serious complications, including airway obstruction.
- Tuberculosis: A less common cause of lymphadenitis, especially in areas with high prevalence, which requires specific treatment and can have significant consequences if missed.
- Rare diagnoses
- Sjögren's syndrome: An autoimmune disorder that can cause swollen lymph nodes and salivary gland enlargement, though it's less likely given the acute presentation.
- Cat-scratch disease: Caused by Bartonella henselae, transmitted through cat scratches, which can lead to swollen and painful lymph nodes, particularly in the neck.
- Toxoplasmosis: A parasitic infection that can cause lymphadenopathy, though it's more commonly associated with other systemic symptoms.
