Extraskeletal Ewing sarcoma is rare. The common locations of extraskeletal Ewing sarcoma include the paravertebral region, lower extremities, and chest wall. Primary pulmonary Ewing sarcoma is extremely rare. Because Ewing sarcoma is sensitive to specialized chemotherapy regimens, accurate diagnosis is therefore critical. The diagnosis of pulmonary Ewing sarcoma can be challenging and need immunohistochemical and cytogenetic analyses. Imaging findings of pulmonary Ewing sarcoma have been rarely reported. This report describes a case of primary pulmonary Ewing sarcoma with immunohistochemical, cytogenetic, CT, and FDG PET/CT findings.
