PET/CT Imaging for Solitary Primary Bone Lymphoma of Thoracic Vertebra

摘要

Primary bone lymphoma without classic nodal lesions or advanced disease may be mistaken for other osseous diseases, especially when involving a single bone site. In this patient, a series of imaging modalities including MRI, bone scan, and F-18-FDG PET/CT revealed only 1 solitary osseous lytic lesion with abnormal uptake in the third thoracic vertebra, suggesting a primary skeletal malignancy. The subsequent histopathologic examination confirmed the diagnosis of diffuse large B-cell lymphoma. After chemotherapy, he achieved an excellent clinical and metabolic response.
