Subacute cervical lymphadenitis

Subacute cervical lymphadenitis has a duration between 2 to 6 weeks.

Assess patients with subacute cervical lymphadenitis who have persistent fever for additional symptoms and exposure history. If indicated, consider testing for cytomegalovirus (CMV), Epstein–Barr virus (EBV), Toxoplasma gondii, Bartonella henselae (see Bartonella infections), Mycobacterium tuberculosis (see Tuberculosis), HIV and syphilis. CMV and EBV are common causes of subacute bilateral cervical lymphadenitis, especially if lymphadenopathy is present in other areas of the body. Noninfective causes include rheumatologic conditions and cancer.

Consider imaging and lymph node biopsy; investigations should be guided by expected aetiology – seek expert advice.
