A Case of Mediastinal Leiomyosarcoma Demonstrated on FDG PET/CT Imaging

A 56-year-old man presented with persisting chest tightness over 1 month. A mediastinal mass was found by chest radiography. To further evaluate the mass, chest CT was performed and the malignancy was suspected. Staging FDG PET/CT demonstrated a hypermetabolic lesion located in the left middle mediastinum without extra-lesion involvement. The lesion pathologically confirmed mediastinal leiomyosarcoma after surgical resection.
