FDG PET/CT in RelapsingPolychondritis: Whole-Body Cartilage Mapping, Disease Activity Assessment, and Diagnostic Utility — A Single-Centre Experience (EANM 2026) - Sep 29, 2026 - Abstract #OP-815; Pres time: Oct 21, 2026; 08:00 AM - 09:30 AM; Location: Hall F1; "The most extensive case (on steroids and rituximab) showed active involvement of the glottis, subglottis, trachea, bilateral main bronchi, thyroid, bilateral arytenoid and cricoid cartilages, and xiphoid (tracheal SUVmax 38.7; laryngeal SUVmax 30.9), confirming residual active disease despite treatment... FDG PET/CT provides clinically valuable information in RPC beyond conventional imaging by: (1) distinguishing active cartilage inflammation from structural damage; (2) mapping full airway disease extent; (3) identifying active disease in atypical presentations; (4) excluding active chondritis when PET is negative; and (5) monitoring treatment response. These findings support incorporating FDG PET/CT into the RPC diagnostic and monitoring algorithm."
