A large exophytic left orbital soft tissue extraconal mass seen arising from the superior aspect of the orbital cavity, inseparable from the superior oblique muscle.
The mass causes mass effect upon the adjacent structures; displacing the muscles anteroinferior causing proptosis of the globe, stretching the optic nerve and deforming the superior aspect of the orbital cavity, extending to the preseptal compartment, without definite bone involvement or posterior orbital canal extension.
The mass appears isointense to adjacent muscles on T1WI, and hyperintense on T2WI with areas of signal void and areas of restricted diffusion, showing avid post-contrast enhancement.
The remainder of the orbit is unremarkable, and the contralateral orbit is normal.
