CTICasesPseudomonas lymphadenitis post-lung transplantation
Imaging findings
CT and MRI show confluent, necrotic mediastinal/hilar lymphadenopathy adjacent to a small bronchial anastomosis dehiscence, in a double lung transplant recipient for cystic fibrosis.
Key takeaways
Airway colonization by resistant organisms (such as Pseudomonas in CF patients) can cause bronchial anastomotic dehiscence. Subsequent tracking of bacteria into the mediastinum leads to necrotizing lymphadenitis.
