Differential Diagnosis for Hepatitis with Enlarged Mediastinal Lymph Node

Single Most Likely Diagnosis

  • Tuberculosis (TB): Given the combination of hepatitis and enlarged mediastinal lymph nodes, TB is a strong consideration, especially in regions where TB is prevalent. TB can cause both liver involvement (hepatitis) and lymphadenopathy, including mediastinal lymph nodes.

Other Likely Diagnoses

  • Lymphoma: Both Hodgkin's and non-Hodgkin's lymphoma can present with hepatomegaly (enlarged liver) and lymphadenopathy, including mediastinal lymph nodes. The liver involvement could be due to direct infiltration by lymphoma cells.
  • Sarcoidosis: This is a systemic granulomatous disease that can affect multiple organs, including the liver and lymph nodes. It often presents with lymphadenopathy, including mediastinal nodes, and can cause liver dysfunction.
  • Infectious Mononucleosis: Caused by Epstein-Barr virus (EBV), it can lead to hepatitis and lymphadenopathy. Although less common, it's a consideration, especially in younger patients.

Do Not Miss Diagnoses

  • Malignant Histiocytosis: A rare but aggressive condition that can present with systemic symptoms, including liver dysfunction and lymphadenopathy. It's crucial to consider due to its poor prognosis if left untreated.
  • Lymphoproliferative Disorders: Disorders such as Castleman disease can present with lymphadenopathy and systemic symptoms, including liver involvement.

Rare Diagnoses

  • Kikuchi-Fujimoto Disease: A rare, self-limiting condition that can cause lymphadenopathy and systemic symptoms, including liver involvement.
  • Kimura Disease: A chronic inflammatory disorder that can cause lymphadenopathy and eosinophilia, with potential liver involvement, though it's more commonly associated with lymph nodes in the head and neck region.
  • Whipple's Disease: A rare, systemic bacterial infection that can cause malabsorption, weight loss, and lymphadenopathy, including mediastinal nodes, along with liver dysfunction.
