有趣病例70:双肺散在小结节,什么病?

先看一张CT!

双肺散在小结节!

临床上经常遇到!

什么病?

转移性肺癌?不是很典型。典型的转移一般是大小不等的结节。当然了,如果有肿瘤基础,首先考虑转移。

感染?有可能!但是,什么类型的感染?

肺结核?病灶形态单一,不像,但是有可能。

血管炎?有可能,但是,不是很像。

尘肺?不像。结节太散!

类风湿结节?没有依据。

这种双肺散在小结节,诊断挺困难的!

其实,我也没有特别好的思路。只是今天偶然间看到这个病例,顺便和大家分享。

希望在病例学习中,慢慢的总结经验。

Objective: To study the CT appearances of primary pulmonary histoplasmosis (PPHP) and evaluate the diagnostic values of CT for PPHP.

Methods: The clinical materials and multi-slice spiral CT appearances in 8 patients with PPHP proved pathologically were reviewed retrospectively.

Results: Single or multiple pneumonia-like lesions were seen in 3 cases, single or multiple nodules or masses were in 4 cases, and both pneumonia-like lesions and nodules or masses in 1 case. Calcification and halo sign were common, and only slight enhancement was demonstrated after intravenous contrast administration on CT.

Conclusion: CT is helpful imaging method in the diagnosis and differential diagnosis of PPHP combining with clinical materials although the CT appearances are not specific.

目的:研究原发性肺组织胞浆菌病(PPHP)的CT表现,评价CT对PPHP的诊断价值。

方法:回顾性分析8例经手术病理证实的PPHP患者的临床资料和多层螺旋CT表现。

结果:单发或多发肺炎样病变3例,单发或多发结节或肿块4例,肺炎样病变合并结节或肿块1例。钙化和晕征是常见的,静脉注射造影剂后CT仅显示轻微强化。

结论:虽然CT表现不具特异性,但结合临床资料,CT对PPHP的诊断和鉴别诊断有一定的帮助。
