Two cases of occult basal encephalocele protruding through defects in the greater wing of the sphenoid bone are presented. The cases are unique in that they occurred in adults with non-localizing symptoms and were eloquently imaged by computed tomography (CT) and magnetic resonance (MR). While the theoretical existence of this type of encephalocele has been recognized, no documented cases of transalar sphenoidal encephalocele are known to have been reported in the radiology or surgery literature.
本文报告两例隐匿性基底脑膨出经蝶骨大翼缺损处突出的病例。这两例病例的独特之处在于，它们发生在具有非定位性症状的成年人中，并通过计算机断层扫描（CT）和磁共振成像（MR）进行了清晰的成像。虽然这种类型的脑膨出的理论存在已得到认可，但在放射学或外科文献中尚无经蝶骨大翼脑膨出的文献记载病例报告。
