肺硬化型血管瘤CT表现与病理对照

CT findings and pathology of pulmonary sclerosis hemangioma

目的分析肺硬化型血管瘤(PSH)CT影像特点,提高对PSH诊断水平。方法收集经病理证实为PSH患者11例,全部病例均作胸部CT平扫及增强扫描,并对靶病灶进行薄层多方位重建,分析CT表现,总结影像学特点。结果 11例PSH,CT平扫均表现为肺内孤立性圆形、类圆形结节或肿块影,密度均匀,边缘光滑,无深分叶,增强扫描病灶均明显强化。病理以血管瘤样及乳头样组织结构为主者,强化明显而迅速;以实性及硬化性组织结构为主者,为渐进性明显均匀强化。结论肺硬化型血管瘤少见,CT表现具有一般良性肿瘤特征,但缺乏特异性,病灶周边出现"贴边血管征"、"空气新月征"可提示性诊断,确诊仍需病理学检查。

Objective To analyze the CT imaging features of pulmonary sclerosis hemangioma（ PSH） and to improve the diagnostic level of PSH. Methods The pathological changes of PSH were collected and 11 cases were confirmed by pathology,and all cases were scanned with plain CT scan and enhanced scan. The target lesion was characterized by multi orientation reconstruction and CT imaging. Results The CT scan of 11 cases of PSH showed round pulmonary solitary,round nodule or lump,uniform density,smooth edge,and no deep lobe,and the enhanced scanning focus was obviously enhanced. The pathological changes of tumor and papillary tissue were obvious and rapid,and the pathological changes of bag and solid structure was progressively strengthened. Conclusion Pulmonary sclerosing hemangioma is a rare disease,and its CT features are generally benign tumor characteristics,but the lack of specificity. ＂Welt lesions of the peripheral vascular sign＂and＂air crescent sign＂can be helpful for diagnosis,but the confirmed diagnosis still need pathological examination.
