摘　　要：目的探讨肺多形性癌(PC)的18F-FDG PET/CT显像表现。方法搜集7例经病理证实的肺PC患者的临床资料,患者均行18F-FDG PET/CT显像检查,分析其PET/CT表现。结果 7例肺PC患者中,4例位于右肺上叶,1例位于右肺中叶,2例位于左肺上叶。4例伴胸膜、胸壁侵犯,3例伴淋巴结转移,1例伴肾上腺转移,1例伴脑转移。PET显像示肺内肿瘤均呈团块状不均匀高代谢,内见放射性减低区或缺损区,胸膜及胸壁侵犯、淋巴结转移、肾上腺转移或脑转移呈结片状、结节状高代谢,CT示肺内肿瘤呈软组织等低混杂密度肿块影,边界清晰,未见明显分叶、毛刺等征象,其中2例病灶内见钙化,2例伴胸腔积液。结论肺PC的18F-FDG PET/CT显像表现具有一定的特点,且能较全面、准确地评估患者病情,对临床诊疗有重要的提示意义。Objective To investigate the features of PET/CT imaging in pulmonary pleomorphic carcinoma（ PC）.Methods Seven patients with pathology proven PC were retrospectively studied.18F-FDG PET image and CT scan were performed in all cases. CT images,PET images and PET / CT fusion images of the same patient were analyzed frame by frame. Results In seven cases of PC,four cases were in superior lobe of right lung,one case in middle lobe of right lung,and two cases in superior lobe of left lung were found,including four cases with pleural and chest wall encroachment,three cases with lymph node metastasis,one case with adrenal gland metastasis,and one case with brain metastases. PET imaging showed mass with non-uniform abnormal radioactive uptake in PC. Well defined nodular radioactive uptake was observed in pleural and chest wall encroachment,lymph node metastasis,adrenal gland metastasis and brain metastases. CT imaging showed punctate calcifications in two cases and pleural effusion in two cases. Conclusion Pulmonary PC has special features on PET / CT imaging. The utilization of functional and morphological images by PET / CT for PC has great significance for clinical diagnosis and therapy.
