Learning Objectives: In regard to patients with pulmonary metastases secondary to well-differentiated thyroid cancer, the objectives of this educational exhibit are to: 1. List the various diagnostic imaging modalities available, 2. Describe the various findings on the various diagnostic imaging modalities, 3. Discuss the prognostic significance of the various findings.
Abstract Body: The prognosis in patients with well-differentiated thyroid cancer with distant metastases to lung, bone, brain, liver, kidney, and/or skin is reduced and varies by location. However, within a specific location, the prognosis can also be quite variable. Lung is one such example, and multiple publications have attempted to further characterize the prognosis of patients with pulmonary metastases based on the findings on various diagnostic imaging modalities. The objective of this educational exhibit is to present a review of the literature regarding the significance of the various pulmonary findings on chest-x-ray, non-contrast CT, radioiodine whole body images (e.g. macronodular, micronodular, diffuse, focal), and 18-F fluoro-deoxy-glucose positron emission tomography. With a better assessment of the prognosis of a patient with pulmonary metastases, the patient and the treating physician(s) will be better able to weigh the risks and benefits of the available treatment options.
