极度屏气潜水(breath-hold diving)后出现短暂性失语和头痛。患者进行了大约30次屏气潜水,持续大约2分钟,30米深,大约5个小时。

脑 MRI(图 A-C)显示左侧额叶白质损害,无弥散抑制,无强化或占位效应。

经过三期高压氧治疗后1个月复查,患者一直无症状,病灶几乎完全消失(下图 D)。下图 A 为首次 Flair 左额皮层下高信号,未累及皮层下 U-型纤维;B 图DWI病灶呈高信号;C 图为 ADC,表观扩散系数图值未见降低,提示无弥散抑制;D 图为1个月后复查 Flair,现实皮层下病灶消失:





反复屏气潜水血和组织中氮聚集,这会引起内皮功能障碍和血脑屏障破坏,导致微血管系统通透性增加,以至于引起血管源性水肿。
