    球形肺炎12例CT表现分析

    CT diagnosis of spherical pneumonia: a report of 12 cases

    • 摘要: 目的:分析球形肺炎的CT表现,探讨CT诊断及鉴别诊断价值。方法:回顾性分析12例经临床及影像学确诊的球形肺炎的CT表现。结果:12例球形肺炎较常见的CT表现是病灶易发生在两肺下叶(背侧多见)。病变两侧缘垂直于胸膜,呈刀切样平直边缘,病变呈方形,即"方形征",可作为其特征性表现。边缘模糊、毛糙或呈锯齿形,可见"晕征"。大部分病灶周围血管纹理增强,靠近胸膜处病灶胸膜反应明显。抗感染治疗后明显好转,肺门及纵膈未见肿大淋巴结。结论:球形肺炎与肺内其他球形病变的CT表现有相似之处,但球形肺炎具有较特殊的炎性病变CT征象,结合抗感染治疗动态观察,诊断应无困难。CT上应注意与周围型肺癌、结核球、肺梗死及早期和进展期传染性非典型肺炎鉴别。

       

      Abstract: Objective: To analyse the imaging features of spherical pneumonia(SP) and to differentiate the SP from other spherical lesions.Methods: Twelve cases of SP clinically verified were analyzed retrospectively.Results: The CT findings were as follows:lesions were most frequently located in both lobus inferior pulmonis.Bilateral margins of the lesions were perpendicular to pleura with a straight cut-edge presenting a ‘square sign’.Edge unsharpness,crude or Indentation ‘Halo-sign’,intensified vascular markings could also be seen;Adjacent pleural thickness,reduce of lesions after anti-inflammatory therapy was inclined to SP.There were no mediastinal and hilar lymph enlargememt.Conclusions: CT exam was an effective way to diagnose and differentiate SP from other spherical lesions.
