What is the most common complication of orbital lymphangioma?
Hemorrhage within cystic compartments of the mass.
What is the imaging modality of choice for orbital mass characterization?
Orbital MRI with and without gadolinium injection.
In the case of orbital lymphangioma the encasement of which anatomic structure must be fully evaluated by the term of degrees?
Optic nerve sheath complex.
There is solid appearing well-defined and lobulated margin intraconal mass lesion within the left orbital cavity which has completely encased the optic nerve sheath complex and also has an impression on adjacent extraocular muscles and it caused left side proptosis.
There is also remodeling of the left orbit medial wall due to the impression of the mass on the adjacent medial rectus muscle and medial orbital wall.
