Nonosseous uptake in Tc-hydroxymethylene bone scintigraphy should always be evaluated for any possibility of pathological changes. We share interesting images of a 60-year-old woman initially investigated for suspected osteomyelitis of the left femur but found to have an extraosseous uptake in the right hemithorax on bone scintigraphy. Plain chest radiograph followed by contrast-enhanced CT of the thorax revealed the presence of a lung mass in the right lower lobe with no lymphadenopathy. CT-guided biopsy yielded fibrocollagenous tissue, partly lined by benign pneumocytes. The F-FDG-avid lung mass was confirmed to be sclerosing pneumocytoma postlobectomy.
Tc-亚甲基二膦酸盐骨显像中的非骨摄取应始终评估任何病理变化的可能性。我们分享了一个有趣的病例图像，一位 60 岁女性最初因疑似左股骨骨髓炎而接受检查，但骨扫描显示右侧半胸部有骨外摄取。胸部平片和增强 CT 显示右下肺有一个肿块，无淋巴结肿大。CT 引导下活检得到纤维胶原组织，部分被良性肺泡细胞覆盖。肺叶切除术后，FDG 摄取的肺肿块被证实为硬化性细支气管肺泡细胞瘤。
