A case of primary primitive neuroectodermal tumor (PNET) of the chest wall in an adolescent is presented with imaging findings including 18F-fluorodeoxyglucose (18F-FDG) positron-emission computed tomography (PET-CT). To date, radiological description of the PNET of the chest wall has mainly been carried out by radiographic analysis, computed tomography (CT), and magnetic resonance imaging (MRI). We demonstrated that 18F-FDG PET-CT visualizes the active focus of glucose metabolism of PNET of the chest wall and is effective for the preoperative evaluation of patients with this tumor.
