Female, caucasian, 74 years old, asymptomatic, had a routine chest X-rays done 4 years before. This exam showed a regular mass in the upper third of the right hemithorax (Fig. 1). A CT scan suggested a pleural tumor as a possible diagnosis (Fig. 2). She refused a biopsy or a surgery that was the proposed treatment. She was lost of follow-up. Currently she came back with chest pain and shortness-of-breath and a new radiological study,including chest X-rays, CT scan and MRI (Fig. 3 to 5) showed that the lesion was 3 or 4 times bigger. At this point she accepted the operation.
