肺错构瘤的综合影像学诊断

目的探讨肺错构瘤的X线、CT表现及其诊断价值。方法回顾性分析16例经手术病理证实的肺错构瘤的影像学资料。结果左肺发病6例，右肺10例；除2例出现浅分叶外，其余所有病灶均表现为边界清楚的类圆形结节影，所有病例均为单发病灶。5例胸片病灶表现为边界清楚结节影；11例行cT检查，均表现为边界清楚的结节影，9例薄层扫描可见病灶内脂肪，增强扫描后病变呈轻度强化。结论x线有助于错构瘤的检出，薄层cT平扫及增强扫描对其诊断价值较高。

Pulmonary hamartoma: imaging findings

Objective To investigate the diagnostic value of X-ray film, CT features on pulmonary hamartoma. Methods The radiographic materials and clinical information of 16 patients with pulmonary hamartoma confLrmed by pathology were retrospective reviewed. Results There were 6 lesions in left lung and 10 lesions in right. Except for 2 lesions with light lobulous margin, all other lesions showed clearly defined round nodule. All of 16 cases were single lesion. Chest plain film of 5 cases and 11 cases of CT showed as nodules with clear boundary. Fat density was found inside the lesion in 9 cases with thin-slice scan, and the lesions showed slightly enhancement after administration of contrast medium. Conclusion X-ray film can be helpful in detection of hamartoma, thin-slice computed tomography scan and contrast enhancement have higher diagnosis value than plain film.
