Imaging findings
Nodular and segmental thickening of the tracheal wall, with similar nodular thickening and narrowing of the left mainstem bronchus. A soft tissue density lesion was also noted in the left lower lobe.
Key takeaways
Tracheobronchial involvement with nodular wall thickening and narrowing is a less common but important manifestation of Granulomatosis with Polyangiitis (Wegener's). Patients typically have positive c-ANCA and systemic symptoms like hearing loss and mastoiditis.
