肺错构瘤(pulmonary hamartoma)是肺内良性肿瘤中最常见的一种,居肺内孤立结节病变的第3位,占5%~10%[1]。发现及诊断本病主要依靠CT检查,主要CT表现为肺内孤立性结节灶。肿瘤内部含有一定的脂肪成分、软骨及钙化,故部分肿瘤在CT上能被检出脂肪或爆米花样钙化而具有特征性,约50%病例无典型的CT影像特征,需要与不典型周围型肺癌和其他孤立性肺结节(Solitary Pulmonary Nodules,SPN)或肿块鉴别。本病罕有恶变,因此能术前明确诊断并进行随访可以避免手术等不正确的治疗。本文回顾性分
Pulmonary hamartoma is the most common type of lung benign tumor, ranking third in isolated pulmonary nodules, accounting for 5% to 10%. Discovery and diagnosis of the disease rely mainly on CT examination, the main CT manifestations of solitary pulmonary nodules. Tumor contains certain fat content, cartilage and calcification, so some of the tumor can be detected on the CT fat or popcorn calcification and has the characteristics of about 50% of cases without typical CT image features, and atypical peripheral type Lung cancer and other solitary pulmonary nodules (SPN) or mass identification. The disease rarely malignant, so can a clear diagnosis before surgery and follow-up to avoid surgery and other incorrect treatment. This article retrospectively points
