Imaging findings
A patient with subglottic stenosis and a tracheostomy showed a markedly thick and abnormal airway extending into the bronchi. Medical history included a colectomy for ulcerative colitis years prior. Biopsy revealed ulcers with acute on chronic inflammation, with no microbial growth.
Key takeaways
This case highlights ulcerative colitis tracheobronchitis, a rare but known extracolonic manifestation of UC that can occur years, even decades, after colectomy. It can be mistaken for vasculitis but is distinguished by seronegativity and specific biopsy findings of acute on chronic inflammation and ulceration.
