CTICasesMycobacterium Fortuitum Infection in Achalasia
Imaging findings
CT chest shows a severely dilated, fluid-filled esophagus (achalasia) with surrounding peribronchial tree-in-bud nodules, bronchiectasis, and focal consolidation in both lungs. Sputum cultures grew Mycobacterium fortuitum.
Key takeaways
Mycobacterium fortuitum is a rapidly growing atypical mycobacterium. It is strongly associated with chronic, subclinical lipid aspiration in patients with esophageal motility disorders like achalasia. Treating the underlying achalasia is essential to prevent recurrent aspiration and reinfection.
