Fibrosing mediastinitis manifesting as thoracic prevertebral thin band-like mass on MRI and PET-CT.
To our knowledge, no report exists of a posterior mediastinal thin band-like mass as a manifestation of fibrosing mediastinitis. A man showed right pleural effusion on chest radiograph. On CT, there was a band-like mass on thoracic prevertebral area. MRI demonstrated the enhancing longitudinal band-like mass all along the vertebrae on coronal and sagittal scans. It was hypermetabolic on PET-CT and there was another hot mass in the presacral area. Additional pelvic MRI showed presacral mass with aortic encasement. Biopsy specimen was consistent with fibrosing mediastinitis. We report a case of fibrosing mediastinitis of posterior mediastinum manifesting as thoracic prevertebral band-like mass and discontiguous presacral, periaortic mass studied with CT, MRI and PET-CT.
