摘要 【目的】分析肺母细胞瘤的PET-CT影像学特征。【方法】1例27岁男性,因“发热伴咽痛半月”入院,抗感染治疗后好转,治疗过程中发现右肺下叶占位病变,给予常规胸部增强CT、支气管镜、PET-CT、穿刺活检等检查最后确诊为肺母细胞瘤,结合本例病例诊疗过程,回顾性分析肺母细胞瘤的临床及影像学特征。【结果】胸部增强CT显示:右肺下叶占位性病变,其内密度欠均匀,见分叶及血管集束征,增强扫描不均匀强化。¹⁸F-FDG PET-CT检查发现病灶葡萄糖代谢增高,行肿块切除术,术后病理学检查确诊为肺母细胞瘤。【结论】¹⁸F-FDG PET-CT检查对肺母细胞瘤的病灶定位及定性诊断有良好价值,疑似肺母细胞瘤病例可早期选择PET-CT检查。

Abstract：【Objective】To analyze the PET-CT imaging features of pulmonary blastoma.【Methods】A 27-year-old male was admitted to hospital with fever with pharyngeal pain and improved after anti-infection treatment. space occupying lesions in the lower lobe of the right lung were found during the treatment.Routine chest enhanced CT, bronchoscopy and PET-CT, puncture biopsies were used, and pulmonary blastocytoma to was diagnosed finally. Combined with the diagnosis and treatment process of this case, the clinical and imaging features of pulmonary blastocytoma were analyzed retrospectively. 【Results】Enhanced chest CT showed that the density of space-occupying lesions in the lower lobe of the right lung was not uniform, lobulated and vascular cluster signs were seen, and uneven enhancement of enhanced scan was observed. ¹⁸F-FDG PET-CT showed increased glucose metabolism in the lesion. Lumpectomy was performed. Postoperative pathological examination confirmed the diagnosis of pulmonary blastoma.¹⁸FDG PET-CT examination has good value to location and diagnosis pulmonary blastoma. 【Conclusion】¹⁸F-FDG PET-CT examination has good value in localization and qualitative diagnosis of pulmonary blastoma. PET-CT examination can be used early in suspected cases of pulmonary blastoma.
