Answer

A case report found positron emission tomography (PET) to be invaluable in confirming the diagnosis of an invasive malignant thymoma. [5] Although CT revealed evidence of an anterior mediastinal mass, PET showed a hypermetabolic mass consistent with this location, thereby raising suspicion of malignancy. Subsequent resection of the mass revealed a minimally invasive thymoma due to capsular invasion. PET should be added to the armamentarium as an available diagnostic modality to aid in staging and excluding extramediastinal involvement. [5]
