Differential Diagnosis for Lymph Node Swelling and WBC of 11
Single Most Likely Diagnosis
- Viral Pharyngitis: This is a common condition that can cause lymph node swelling and a mild increase in white blood cell (WBC) count. The symptoms often include sore throat, fever, and swollen lymph nodes, which are consistent with the presentation.
Other Likely Diagnoses
- Bacterial Pharyngitis: Similar to viral pharyngitis but caused by bacteria, this condition can also lead to lymph node swelling and an elevated WBC count. Symptoms may include severe sore throat, fever, and swollen lymph nodes.
- Mononucleosis (Mono): Caused by the Epstein-Barr virus, mono can lead to significant lymph node swelling, particularly in the neck, and an elevated WBC count. Other symptoms include fever, sore throat, and fatigue.
- Tuberculosis (TB): Although less common in some regions, TB can cause lymph node swelling, especially in the neck, and can lead to an elevated WBC count. Other symptoms may include cough, weight loss, and night sweats.
Do Not Miss Diagnoses
- Lymphoma: A type of cancer that affects the immune system, lymphoma can cause significant lymph node swelling and changes in the WBC count. It is crucial to consider this diagnosis to ensure timely treatment.
- Hodgkin Disease: Another form of lymphoma, Hodgkin disease can present with lymph node swelling, fever, and changes in WBC count. Early diagnosis is critical for effective treatment.
- Leukemia: A cancer of the blood and bone marrow, leukemia can cause an elevated WBC count and lymph node swelling. It is essential to rule out this diagnosis due to its severe implications.
Rare Diagnoses
- Castleman Disease: A rare disorder that involves an overgrowth of cells in the lymph nodes, Castleman disease can cause lymph node swelling and changes in WBC count. It is often associated with other systemic symptoms.
- Kikuchi-Fujimoto Disease: A rare condition that affects the lymph nodes, Kikuchi-Fujimoto disease can cause lymph node swelling, fever, and changes in WBC count. It is more common in young women and often resolves on its own.
- Sarcoidosis: A condition that can affect multiple parts of the body, sarcoidosis can cause lymph node swelling and changes in WBC count. It is characterized by the formation of granulomas in various organs.
