What evaluation is best for an isolated, enlarged cervical lymph node?

Abstract

The evaluation and follow-up of an isolated, enlarged cervical lymph node is determined by the presence of inflammation, duration, size, and associated symptoms. For patients with inflammatory symptoms (ie, fever, pain, erythema, and recent infection), a single course of broad-spectrum antibiotic and reassessment in 1 to 2 weeks is reasonable (strength of recommendation [SOR]: C, expert opinion). If lymph node enlargement persists despite antibiotics, yet an infectious or inflammatory cause is still suspected, further evaluation may include a PPD skin test and chest radiograph1 (SOR: C, expert opinion).
