Unidentified Object in the Mediastinum: A Case Report of Severe Aortic Calcification in a Patient With Rheumatoid Arthritis.

We present a case of an 80-year-old female with a past medical history of rheumatoid arthritis (RA) who was incidentally found to have severe circumferential thoracic aortic calcification detected on chest X-ray and computed tomography (CT) scan of the chest. This case highlights the chronic inflammatory state and immunological vascular damage as key mechanisms for the accumulation of dystrophic calcification in the blood vessels and soft tissues of patients with autoimmune and inflammatory diseases. It also emphasizes the importance of coordinated multidisciplinary care and management between different specialties including primary care physician (PCP), cardiology, and rheumatology to address all the challenges related to disease control and optimize cardiovascular risk factors in this patient population.
