Maxillofacial Spindle Cell Sarcoma With Lung Metastases on FDG PET/CT Imaging.

A 45-year-old man presented with episodes of cough and chest discomfort. CT examination showed multiple nodules of bilateral lungs. The pathology of CT-guided biopsy was consistent with spindle cell sarcoma. FDG PET/CT scan was performed to detect the primary lesion, which showed that in addition to multiple hypermetabolic pulmonary nodules, a mass in the right maxillofacial region with high FDG uptake was also found. A biopsy confirmed spindle cell sarcoma.
