We have reported 2 cases of pulmonary hamartoma focusing on detecting intranodular fat, which is one of CT features suggestive of pulmonary hamartoma, using dual-energy CT analyses. For patient 1, a 73-year-old man was pointed out to have a nodular opacity on chest radiograph of pretreatment workup for retinal detachment. In patient 2, a 66-year-old woman with uterine carcinoma admitted for preoperative assessment. Both patients underwent dual-energy CT examination and the pulmonary lesions exhibited a downward-sloping curve at lower X-ray energies on attenuation curve of virtual monochromatic images, which suggested fatty tissue. Dual-energy CT analysis can help diagnose pulmonary hamartoma with detection of intralesional fatty tissue.
我们报告了2例肺错构瘤，重点是利用双能CT分析检测结节内脂肪，这是提示肺错构瘤的CT特征之一。病例1为一名73岁男性，在视网膜脱离术前检查的胸部X光片上发现有结节状不透明影。病例2为一名66岁患有子宫癌的女性，因术前评估入院。两名患者均接受了双能CT检查，肺部病变在虚拟单色图像的衰减曲线上，在较低X线能量处呈现向下倾斜的曲线，提示为脂肪组织。双能CT分析通过检测病灶内脂肪组织有助于诊断肺错构瘤。
