Abstract:
Objective To make a further understanding of the CT features of intraorbital meningioma,and to improve the level of CT diagnosis. Methods The imaging data of CT and clinical information of 17 cases with operatively and pathologically proved intraorbital meningioma(primary or secondary) from October 1997 to October 2006 in our hospital were retrospectively analysed.Results There were 11 optic nerve sheath meningiomas,4 orbital bone meningiomas and 2 sphenoid ridge meningiomas.On contrast-enhanced CT scan,most of the cases displayed an even enhancement.The "orbit sign""sleeve sign" and the hyperostosis of orbital bone were characteristic features of intraorbital meningioma.Conclusion CT examination plays an important role in diagnosing intraorbital meningioma.
