肺硬化性血管瘤的CT诊断

目的探讨肺硬化性血管瘤（PSH）的CT表现,旨在提高对其CT表现的认识。方法回顾分析18例经手术及病理证实的PSH的CT资料。结果PSH多见于中青年女性,表现为直径1.0-5.0 cm,境界清晰的圆形、类圆形肺内结节或肿块;CT平扫密度均匀,有时见粗大点片状钙化,1例较大病灶内可见囊性变;CT增强见均匀或不均匀强化,且有延迟强化。结论CT扫描,尤其增强CT及病灶薄层扫描有助于SHL的诊断及鉴别诊断。

The CT Diagnosis of Pulmonary Sclerosing Hemangioma

Objective To study the CT features of pulmonary sclerosing hemangioma(PSH),so that to improve the imaging diagnostic abilities.Methods 18 cases pathologically proven PSH were included in this retrospective article.Results PSH should be considered in young and middle-aged female patients.On CT,the lesion p resented as well-defined,round and oval shaped mass or nodule.A homogeneous soft-tissue mass on unenhanced CT;calcification was found in some lesions;in 1 case,cystic-like area was found within large tumors.Homogene-ous or heterogeneous enhancement after contrast administration;on delayed phase scans,some of them demonst-rated late enhancement.Conclusion CT especially thin-section CT with contrast media is of benefit in diagnosis and differential diagnosis of SHL.
