目的：探讨周围型肺错构瘤的HRCT征象，以提高该病诊断水平。方法回顾性分析手术及病理证实的周围型肺错构瘤23例的CT表现。结果右肺9例（右肺上叶为3例，右肺中叶2例，右肺下叶4例），左肺14例（左肺上叶6例，左肺下叶8例），圆形12例，类圆形8例，浅分叶征3例，边界清楚，无深分叶、毛刺征和卫星病灶。直径1.0～5.4 cm，平均直径约2.6cm，＜3cm 17例。5例病灶内含脂肪，7例既有脂肪又有钙化；8例病灶内有钙化，典型爆米花样钙化3例；所有15例钙化病灶中有11例位于中叶和下叶基底段。3例呈均匀软组织密度影，增强呈轻至中度强化，软组织密度部分强化程度约5～16 HU。结论 HRCT可以显示肺错构瘤特征性的钙化及脂肪密度影，有助于肺内周围型错构瘤的诊断。有脂肪或既有脂肪又有钙化孤立性肺结节或肿块，可以考虑错构瘤。

Objective Type around the HRCT manifestations of pulmonary hamartoma , in order to improve the level of diag-nosis of the disease .Methods Last 14 years retrospective analysis confirmed by surgery and biopsy of peripheral pulmonary hamar -toma 23 cases of CT performance.Results Nine cases of right lung (for 3 cases of the upper lobe of right lung middle in 2 cases, 4 cases were characterized by lower lobe ), 14 cases had left lung (6 cases left upper lobe, left lower lobe 8 cases), 12 cases round, round 8 cases, shallow points Ye Zheng 3 cases, border and clear, no deep lobulated, burr and satellite lesions.1.0~5.4 cm in di-ameter, the average is about 2.6 cm in diameter, less than 3 cm17 cases.5 cases of lesions containing fat , 7 cases there are both fat and calcification;8 cases of lesions with calcification , typical popcorn "calcification in 3 cases;All 11 cases in 15 cases of calcified lesions located in the middle and lower lobe basal segment .3 cases of homogeneous soft tissue density with increase in mild to moderate strengthening , soft tissue density partial reinforcement degree about 5~16 HU.Conclusions HRCT can show pulmonary hamartoma characteristic calcification and fat density with help in the diagnosis of peripheral hamartoma lungs .Fat or there are both fat and calcifi-cation isolated pulmonary nodules or masses , can consider hamartoma;Instead of n/med tuberculosis good hair part containing calcium isolated pulmonary nodules , should think of hamartoma diagnosis .
