Patient Data

Age: 5
Gender: Female
MRI

MRI brain

The intra-orbital and intra-canalicular segments of the left optic nerve show fusiform enlargement and expansion causing proptosis of the left eye-globe. It enhances intensely and homogeneously following administration of contrast.

The left eye-globe, orbital muscles and muscle cone are, otherwise, normal.

Case Discussion

This case demonstrates left optic nerve mass with no chiasmatic extension impressive of optic nerve glioma. The differential diagnosis include optic nerve sheath meningioma which surrounds and compresses the optic nerve. In this case, the optic nerve shows fusiform enlargement with kinking. MRI is more sensetive in detection and characterization of intracranial extension through optic pathway.
