A giant air cell of the left petrous apex was found in a 23-year-old man with ipsilateral facial hypalgesia. The size of the giant air cell depicted on computed tomography was 1.5 x 2.0 x 2.0 cm. A coronal T1-weighted magnetic resonance image showed that the trigeminal nerve was compressed superomedially by a large signal void area that was probably a result of excessive pneumatization of the petrous apex. It is suggested that the facial hypalgesia was caused by the compression by the giant air cell of the petrous apex on the trigeminal nerve.
在一名患有同侧面部痛觉减退的23岁男性中发现左侧岩尖有一个巨大气房。计算机断层扫描显示的巨大气房大小为1.5×2.0×2.0厘米。冠状位T1加权磁共振图像显示，三叉神经被一个大的信号空洞区域向内侧上方压迫，该区域可能是岩尖过度气化的结果。提示面部痛觉减退是由岩尖巨大气房对三叉神经的压迫所致。
