摘要
目的探讨不典型肺硬化性血管瘤(PSH)的CT特征。方法收集6例CT表现不典型、经病理证实的PSH患者影像学资料,分析其CT表现。结果 6例CT平扫表现如下:5例单发,其中3例表现为侧胸壁胸膜肿块、2例跨越斜裂胸膜生长,1例弥漫多发,贴近斜裂胸膜生长;4例形态不规则,2例呈类圆形或结节样;5例边缘见磨玻璃影;胸腔积液1例;囊变3例;粗点状钙化4例。5例接受CT增强扫描,动脉期3例轻度强化、1例中度强化、1例明显强化,静脉期3例强化程度稍增强、1例持续强化、1例CT值稍下降;均见贴近肿瘤边缘走行的血管影。结论不典型PSH CT多表现为不规则肿块,亦可呈多发结节状,可沿侧胸膜或跨越叶间胸膜生长,或伴胸腔积液。
Objective To investigate CT features of atypical pulmonary sclerosing hemangioma （PSH）. Methods Ima- ging data of 6 patients with atypical PSH confirmed by pathology were analyzed. Results Among 6 patients, plain CT showed that there were 5 patients with single lesion, including 3 with lateral chest wall pleural masses and 2 with spanned growth across the oblique fissure pleural, while 1 patient with diffuse and multiple lesions close to the oblique pleura. Irregular shaped tumors and nearly-circular or nodular like tumors were detected in 4 and 2 patients, respectively. The ground-glass opacities around the lesion in 5 cases, hydrothorax in 1 case, cystic degeneration in 3 cases were noticed, while spot calcifications were observed in 4 cases. After administration of contrast media （n= 5）, tumors in 3 cases showed slight enhancement, 1 showed moderate enhancement and 1 showed obvious enhancement in arterial phase, while 3 showed slightly increased enhancement, 1 showed constant enhance and 1 showed slightly reduction in venous phase. The vessels closed to the edges of lesion were observed in all these 5 cases. Conclusion Atypical PSH manifests as irregular bump or multiple nodular and grow across the pleura or along the lateral pleura, with or without hydrothorax on CT.
