Role of 18 F-FDG PET/CT in the Diagnostic Evaluation of a Hypermetabolic Pulmonary Artery lesion: A Case Report of IgG4-Related Disease Mimicking Malignancy (EANM 2026) - Sep 29, 2026 - Abstract #EP-1494; "Systemic treatment was initiated with intravenous methylprednisolone pulses, followed by oral prednisone with rapid tapering and subsequent rituximab therapy. IgG4-RD involving the pulmonary artery is an exceptionally rare condition that may closely mimic vascular malignancy. 18F-FDG PET/CT is essential for lesion characterization, detection of multisystem involvement, and guiding therapeutic strategy."
