Answer:
Oleothorax
The correct answer is oleothorax. This patient had a history of pulmonary tuberculosis in the 1950s, and treatment at this time for this condition involved instillation of oil into the pleural space to collapse the involved lung. The oil was usually aspirated after the treatment was complete, which was usually a period of two years. In this case, the patient was lost to follow up after completing the treatment and the oil was left in place.
