Can 18Fluoro-deoxy-glukose-positron emission tomography/computed tomography be a useful for decision of elective surgery in thoracic aortic aneurysm

Abstract

Thoracic aortic aneurysm (TAA) should be treated before the complications with prophylactic surgery. However, important number of ruptures have been occurred below the cut-off size for surgery. In addition, in some cases, who in the cut-off value limit, decision of surgery may sometimes be difficult. 18Fluoro-deoxy-glukose positron emission tomography/computed tomography (18FDG-PET/CT) may useful such situations. We present a case that, TAA in 18FDG-PET/CT in a patient with larynx carcinoma. He had a TAA with near the cut-off value and increased metabolic activity in baseline imaging. After 3 months, SUVmax value increased and elective surgery was performed. We think that aneurysms may be another pathology that 18FDG-PET/CT potentially be useful apart from imaging malignant diseases.
