Postoperative MRI demonstrated a residual enhancing suprasellar component with improved mass effect on the floor of the third ventricle, mammillary bodies, and optic chiasm, as well as near-complete resolution of the edema involving the bilateral optic tracts

Whatever the structures that appeared on the lateral aspect of the brain were the olfactory bulb, cerebrum, cerebellum, Medulla oblongata, optic lobe, optic chiasm, optic tracts
, and hypophysis.
Tumours may be unilateral or bilateral, affecting the optic nerves, optic tracts
Posterior involvement of the optic tracts
and radiation and lateral geniculate body is less commonly seen.
The subpedunculate body and nerve and other organs associated with the optic tracts
The anterior division is connected to the eyes and frontal filaments via the optic tracts
, and the posterior division is connected to the antennules via the antennular nerves [ILLUSTRATION FOR FIGURE 4A OMITTED].
: Optic tracts
extend posteriorly from angle of chiasma between tubercinerium and the anterior perforated substance.
(9) During intrauterine development, myelination of retinal ganglion cell axons starts from the lateral geniculate body and proceeds through the optic tracts
, chiasm and optic nerves.
Abnormalities of the corpus callosum and optic tracts
can be seen in these patients.
Rudimentary optic tracts
, gliotic lateral geniculate nuclei, thinner calcarine cortex was present, but in my case brain was normal.
