CTICasesPost-TBNA acute bacterial lymphadenitis
Imaging findings
Serial CT scans show rapid enlargement of a right paratracheal lymph node and adjacent ground-glass consolidation within 7 days following a transbronchial needle aspiration (TBNA) biopsy.
Key takeaways
Infectious lymphadenitis is a rare complication of transbronchial needle biopsy (TBNA). It is caused by introducing oral or airway flora into the node during the procedure, leading to rapid nodal enlargement.
