1. Results Of five cases, scaphocephaly was seen in one case and oxycephaly and brachycephaly were revealed in two cases respectively. All cases demonstrated the deepened impressions for cerebral gyri. The antedisplacement of the sphenoid body and the smaller orbit were seen in four cases. One case with oxycephaly demonstrated the enlarged supratentorial cerebral ventricles on CT. One case with brachycephaly showed a depressed skull, narrowing of the optic foramen and obvious protrusion of both eyes on CT. Conclusion The radiological manifestations of cranial stenosis were characteristic.
结果 5例狭颅症，1例表现为舟状头畸形，2例表现为尖头畸形，2例表现为短头畸形，5例均可见脑回压迹加深，4例可见蝶骨体前移及眼眶变浅，1例尖头畸形CT扫描可见幕上脑室扩大，1例短头畸形CT扫描示颅骨内板呈波浪状凹陷，视神经孔变窄，双侧眼球明显突出。
2. Ectopic meningiomas is rarely seen. The tumor always generates in the scalp, cranial bones, orbit, nasal sinus, middle ear, nose, neck, post-peritoreum, semi lunar node and ebonite membrane.
异位脑膜瘤好发于头皮、颅骨、眼眶、鼻窦、中耳、鼻腔、颈部、腹膜后、三叉神经半月神经节、硬脑膜外层等。
3. Cases were invaded into nasal cavity, 6 into ipsilateral ethmoid sinus, 5 into contralateral ethmoid sinus, 4 into maxillary sinus, 3 into orbit and 2 into anterior cranial fossa.
病灶侵及鼻腔7例，同侧筛窦6例，对侧筛窦5例，上颌窦4例，眼眶3例，前颅窝2例。
