“…1) All patients presented with visual deficits such as visual acuity deterioration and bitemporal hemianopsia, and two patients also had hormonal insufficiency. Optic chiasm metastasis was identified in three autopsy cases with multiple brain metastases, 14) and three cases of chiasmal syndrome due to suprasellar metastasis were reported without revealing the precise region of metastasis. 3) One case of optic chiasm metastasis was found expanding the infundibulum and infiltrating the hypothalamus, 9) and one case of metastasis in the pituitary gland extending to the chiasm.…”

“…Only nine cases of metastasis to the optic chiasm have been reported: eight cases of metastasis indirectly to the optic chiasm, 3,9,13,14) and one case of metastasis directly to the optic chiasm. 1) All patients presented with visual deficits such as visual acuity deterioration and bitemporal hemianopsia, and two patients also had hormonal insufficiency.…”

“…1,3,14) Vascular support of the optic chiasm is derived primarily from the caudal side, via small branches of the anterior cerebral artery and the anterior communicating artery. The arteries are often in direct contact with the chiasm.…”

“…The same mechanism was considered in the previous case, 1) but infiltration from metastasis of nearby structures or dissemination from the CSF spread may have occurred in the other cases of optic chiasm metastasis. 3,9,13,14) The differential diagnoses of suprasellar lesion separate from the pituitary gland include craniopharyngioma, germ cell tumor, optic glioma, and metastatic tumor. Craniopharyngiomas have a bimodal peak of incidence, …”

A 61-year-old female, previously treated for lung cancer, presented with a rare case of metastasis directly to the optic chiasm manifesting as visual deficits. Magnetic resonance imaging revealed a suprasellar mass similar to an optic glioma. At surgery, the optic chiasm appeared swollen with hypervascularity over the surface. The bilateral optic nerves and the pituitary stalk appeared normal. A small incision was made on the superior surface of the chiasm and biopsy specimens were taken. The histological diagnosis was adenocarcinoma, which was consistent with the primary lung cancer. She received whole brain irradiation, resulting in mild improvement of her vision. Suprasellar metastatic tumors to the pituitary gland, pituitary stalk, and hypothalamus are well documented, but solitary metastasis within the optic chiasm should be considered as one of several differential diagnoses of suprasellar tumors, in patients with or without a history of treated cancer.
