Oleothorax: A Historic Chest Radiograph Finding

Even though tuberculosis (TB) is an extremely old disease, proper effective treatment for the condition became available only around 1944, with the discovery of streptomycin's effect on Mycobacterium tuberculosis. Until then, surgical approaches had been among some of the treatments employed, which were dropped with the progressive development of antimycobacterial agents. We present a case of an 83-year-old woman, with a history of pulmonary tuberculosis (PT) at the age of 15 years, presenting with a seven-day history of cough, dark sputum, dyspnea, and pleuritic chest pain. She was submitted to a chest radiograph. The exam revealed a large oval calcified mass on the left apex, compatible with oleothorax. Oleothorax should be included in the differential diagnosis of large calcified thoracic masses in older patients.
