Abstract

Imaging description Relapsing polychondritis is a multi-system disorder that can involve the cartilage of the external ear, nose, larynx, trachea, and central bronchi. This disorder is characterized by recurrent inflammation and destruction of the cartilage in these areas. Although uncommon at presentation, respiratory tract involvement occurs in up to 50% of patients at some point during the course of the illness [1–4]. Involved airways are typically thickened along the cartilaginous portions of the wall with sparing of the posterior membranous portion of the wall (Figures 3.1 and 3.2). The wall thickening is typically smooth and diffuse [1–4] and often has increased attenuation ranging from subtly increased to obviously calcified [1] (Figure 3.3). In one-third of patients the airways are narrowed. When narrowing is present it may be either diffuse or focal (Figure 3.4). When expiratory imaging is obtained, tracheomalacia and/or bronchomalacia can be seen in over 50% of patients [1, 2] (Figure 3.5).
