title: Patient With Slow-Growing Mediastinal Mass Presents With Chest Pain and Dyspnea.
abstract: A 52-year-old white woman presented with severe pain over the right upper abdomen and nonpleuritic, right-sided, lower chest-wall pain. Her pain had progressively gotten more frequent and severe over the last 5 months. It was also associated with a nonexertional, pressure-like sensation in the central chest. The patient denied any shortness of breath, fevers, cough, or any sputum production. She was taking levothyroxine for hypothyroidism and was a 30-pack-year current smoker; there was no history of drug abuse or occupational exposure. Previous chest radiographs dating back to 5 years consistently showed an elevated right-sided hemidiaphragm without any infiltrates or effusions; cardiomediastinal structures were unremarkable. She had not had a previous workup for these abnormal findings.
