title: F-18 FDG PET/CT imaging of bulky myxofibrosarcoma in chest wall.
abstract: Myxofibrosarcoma (MFS) has a spectrum of malignant fibroblastic lesions with variably myxoid stroma and pleomorphism. A 67-year-old man with a bulky mass on his chest wall was diagnosed with MFS. He underwent F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography for detection of metastasis. FDG positron emission tomography /computed tomography showed inhomogeneous high FDG uptake (max standardized uptake value, 10.1) in the bulky tumor with no evidence of metastasis, and the tumor was successfully resected. FDG uptake seemed to be reflected by the broad spectrum of pathologic heterogeneity. And MFS should be considered when making a diagnosis of inhomogeneous FDG-avid lesions in the bulky masses of soft tissue.
