"They are classified as teratoid or non-teratoid basing the presence/absence of cartilaginous, muscular, or brain tissue components. Malignant transformation is suspected in presence of Homer Wright or Flexner–Wintersteiner rosettes, brisk mitotic activity, atypia, sarcomatous changes, local and/or extraocular invasion with metastasis 1."

"T1: isointense or mildly hyperintense to vitreous"

"A medulloepithelioma of the optic disc and optic nerve may also be referred to as a diktyoma or teratoneuroma, although the use of these terms is not recommended 1. They are included among the primary tumours of the optic disc and optic nerve in the last WHO classification of eye tumours. Despite being considered distinct entities from the medulloepitheliomas of the ciliary body, they share many histopathologic features with the latter."

"Because of their rarity, there are not many radiological descriptions in the literature. Their characteristics are not specific and are distinct from the medulloepitheliomas of the ciliary body. They appear as intraconal and well-defined masses (sometimes fusiform) centred on the optic nerve or optic disc 3."
