Abstract：
UNASSIGNED: To investigate the short-term changes in chest CT images of low-altitude populations after entering a high-altitude environment.
UNASSIGNED: Chest CT images of 3,587 people from low-altitude areas were obtained within one month of entering a high-altitude environment. Abnormal CT features and clinical symptoms were analyzed.
UNASSIGNED: Besides acute high-altitude pulmonary edema, the incidence of soft tissue space pneumatosis was significantly higher than that in low-altitude areas. Pneumatosis was observed in the mediastinum, cervical muscle space, abdominal cavity, and spinal cord epidural space, especially the mediastinum.
UNASSIGNED: In addition to acute high-altitude pulmonary edema, spontaneous mediastinal emphysema often occurs when individuals in low-altitude areas adapt to the high-altitude environment of cold, low-pressure, and hypoxia. When the gas escapes to the abdominal cavity, it is easy to be misdiagnosed as gastrointestinal perforation. It is also not uncommon for gas accumulation to escape into the epidural space of the spinal cord. The phenomenon of gas diffusion into distant tissue space and the mechanism of gas escape needs to be further studied.

摘要：
■研究进入高海拔环境后低海拔人群胸部CT图像的短期变化。
■在进入高海拔环境的一个月内获得了来自低海拔地区的3,587人的胸部CT图像。分析异常CT表现及临床症状。
■除了急性高原肺水肿，软组织空间积气的发生率明显高于低海拔地区。在纵隔中观察到肺炎，颈肌间隙,腹腔，脊髓硬膜外腔，尤其是纵隔.
■除了急性高原肺水肿，自发性纵隔气肿常发生在低海拔地区个体适应寒冷的高海拔环境时,低压,和缺氧。当气体逸出腹腔时，容易误诊为消化道穿孔。气体积聚逃逸到脊髓的硬膜外腔中也并不少见。气体扩散进入远处组织空间的现象和气体逸出的机理有待进一步研究。
