Abstract

We report two cases of giant cell tumor arising from the rib and their F-18 FDG PET/CT findings. The two patients complained of chest wall pain, and large lobulated soft tissue masses with intense FDG uptake were seen on F-18 FDG PET/CT. A malignant tumor such as osteosarcoma or chondrosarcoma was suspected due to the large size of the mass, bony destruction, and intense FDG uptake. En bloc resection was performed and final pathologic results revealed giant cell tumor of the rib. Giant cell tumor of the rib is very rare, and larger lesions with high FDG uptake can be misdiagnosed as an intrathoracic malignancy arising from the rib, pleura, or chest wall.

摘要

我们报告两例起源于肋骨的骨巨细胞瘤及其F-18 FDG PET/CT表现。两名患者均主诉胸壁疼痛,F-18 FDG PET/CT显示有分叶状大软组织肿块伴FDG摄取增高。由于肿块较大、骨质破坏及FDG摄取增高,怀疑为骨肉瘤或软骨肉瘤等恶性肿瘤。行整块切除,最终病理结果显示为肋骨骨巨细胞瘤。肋骨骨巨细胞瘤非常罕见,FDG摄取增高的较大病变可能被误诊为起源于肋骨、胸膜或胸壁的胸内恶性肿瘤。
