Lateral sphenoid encephalocele, especially within the lateral aspect of the sphenoid sinus, when the sphenoid sinus has pneumatized extensively into the pterygoid recess, are considered exceedingly rare. We report a rare case of lateral intrasphenoidal encephalocele with spontaneous cerebral spinal fluid (CSF) rhinorrhea. Computed tomography demonstrated bilateral arachnoid pit, extensive sphenoid sinus pneumatization, and a defect in the superior wall of the left lateral recess of the sphenoid sinus. Magnetic resonance imaging demonstrated anteromedial temporal lobe herniating through the bony defect.
外侧蝶骨脑膨出,尤其是在蝶窦外侧部分,当蝶窦广泛气化进入翼突隐窝时,被认为极为罕见。我们报告一例罕见的伴有自发性脑脊液鼻漏的蝶窦内外侧脑膨出病例。计算机断层扫描显示双侧蛛网膜凹陷、蝶窦广泛气化以及蝶窦左侧外侧隐窝上壁缺损。磁共振成像显示颞叶前内侧通过骨缺损疝出。
