Abstract

PURPOSE

Our purpose is to describe the CT findings in pulmonary fat embolism syndrome (FES).

METHOD

Chest radiographs and CT scans of six patients with pulmonary FES were reviewed. Initial and follow-up CT findings were noted, and the extent of CT abnormalities was correlated with partial pressure of arterial oxygen (PaO2).

RESULTS

Focal areas of consolidation or ground-glass opacity and nodules were seen in all patients, predominantly in the upper lobes of the lungs. Association between these opacities and pulmonary vessels was indicated in three patients. In the lower lobes of all patients, gravity-dependent opacities predominated. Diffuse ground-glass opacity was noted in five patients. Follow-up CT scans showed rapid improvement in three patients, but the gravity-dependent opacity progressed. The extent of CT abnormalities correlated positively with PaO2 (r = 0.8, p < 0.05).

CONCLUSION

CT findings reflect the pathophysiology of this syndrome, which differs from that of simple capillary permeability pulmonary edema.

摘要

目的

我们的目的是描述肺脂肪栓塞综合征（FES）的CT表现。

方法

回顾了6例肺FES患者的胸部X线片和CT扫描结果。记录初始和随访的CT表现，并将CT异常程度与动脉血氧分压（PaO2）进行相关性分析。

结果

所有患者均可见局灶性实变或磨玻璃样密度影及结节，主要位于肺上叶。3例患者可见这些密度影与肺血管有关。所有患者的下叶均以重力依赖区密度影为主。5例患者可见弥漫性磨玻璃样密度影。随访CT扫描显示3例患者病情迅速改善，但重力依赖区密度影进展。CT异常程度与PaO2呈正相关（r = 0.8，p < 0.05）。
