Diagnostic value of contrast-enhanced ultrasonography in mediastinal leiomyosarcoma mimicking aortic hematoma: A case report and review of literature

Figure 3 Median sagittal and coronal section images of positron emission tomography/computed tomography. Positron emission tomography/computed tomography showed that the mass with high fluorodeoxyglucose (FDG) metabolism surrounded the descending aorta. The maximum standardized uptake value (SUV) was 28.8. A nodule with a high FDG metabolism was observed in the left upper lobe, with a maximum SUV of 9.5. The high metabolic signal in the bladder should represent the excreted drugs. No abnormal increase in FDG metabolism was observed in the rest of the body.
