Axial T1 WI demonstrates, hypointensity and diffuse decrease of diploe spaces and thickening of the calvarial bones' tabula interna and externas. In the left orbita,an extraconal lesion hypointense on T1 WI which displaces extraconal fat and rectus muscle away from the orbital wall is seen. Also the left eyelid is thickened and has got the same signal characteristics with the orbital lesion.

Sagittal T1 WI demonstrates, hypointensity and diffuse decrease of diploe spaces and thickening of the calvarial bones' tabula interna and externas. Posterior fossa is too small and foramen magnum diameter is diminished.
 
Coronal Fat Sat.T2 WI demonstrates, hypointensity and diffuse decrease of diploe spaces and thickening of the calvarial bones' tabula interna and externas. There is a mild hydroceplalus probably due to small posterior fossa.
 
Axial T1 WI demonstrates,an extraconal lesion in the left orbita hypointense on T1 WI which displaces extraconal fat and rectus muscle away from the orbital wall is seen. Also the left eyelid is thickened and has got the same signal characteristics with the orbital lesion.
 
Axial Fat Sat. post IV Gd DTPA T1 WI demonstrates,an extraconal lesion in the left orbita hypointense on T1 WI which displaces extraconal fat and rectus muscle away from the orbital wall is seen. Also the left eyelid is thickened and has got the same signal characteristics with the orbital lesion.The orbital lesion shows marked peripheral enhancement as well as the eyelid.
 
Axial Fat Sat.T2 WI shows an extraconal lesion which demonstrates central hyperintense signal intensity and a hypointense signal intensity peripherally on T2 WI in the left orbita. The lesion displaces extraconal fat and rectus muscle away from the orbital wall. Also the left eyelid is thickened and seems hyperintense.
