Differential Diagnosis for High Grade Fever and Cervical Lymphadenopathy

Single Most Likely Diagnosis

  • Tuberculosis (TB): Given the combination of high-grade fever and cervical lymphadenopathy, TB is a leading consideration, especially in regions where TB is prevalent. The infection can cause significant lymph node enlargement and systemic symptoms like fever.

Other Likely Diagnoses

  • Infectious Mononucleosis: Caused by Epstein-Barr virus (EBV), this condition often presents with fever, sore throat, and lymphadenopathy, including cervical lymph nodes.
  • Lymphoma: Both Hodgkin and non-Hodgkin lymphoma can present with lymphadenopathy, including cervical lymph nodes, and systemic symptoms like fever.
  • Cat Scratch Disease: Caused by Bartonella henselae, this infection can lead to lymphadenopathy, typically in the region draining the site of the cat scratch, and is accompanied by fever.

Do Not Miss Diagnoses

  • HIV Infection: Acute HIV infection can present with fever and lymphadenopathy. Missing this diagnosis could lead to delayed treatment and significant morbidity.
  • Malignancy (e.g., Metastatic Cancer): Certain cancers, especially head and neck cancers, can metastasize to cervical lymph nodes and present with systemic symptoms like fever.
  • Lymphogranuloma Venereum: A sexually transmitted infection caused by Chlamydia trachomatis, which can cause fever, lymphadenopathy, and other systemic symptoms.

Rare Diagnoses

  • Kikuchi-Fujimoto Disease: A rare, self-limiting condition that presents with cervical lymphadenopathy and fever, more common in young women.
  • Kimura Disease: A chronic inflammatory disorder that can cause lymphadenopathy and eosinophilia, typically presenting with fever and lymph node enlargement in the head and neck region.
  • Castleman Disease: A rare disorder that can cause lymphadenopathy, fever, and other systemic symptoms, often involving the cervical lymph nodes.

Each of these diagnoses has a unique set of characteristics and epidemiological factors that can guide further investigation and management. A thorough history, physical examination, and diagnostic tests (such as blood work, imaging, and biopsy) are essential for determining the underlying cause of high-grade fever and cervical lymphadenopathy.
