Solitary metastasis of breast carcinoma in the optic chiasm.
Optic chiasmatic compression from suprasellar metastatic lesions is well known, but metastasis intrinsic to the optic chiasm has not been reported. A 45-year-old woman, with treated breast carcinoma, presented with headache and chiasmatic syndrome from a large suprasellar tumour. At surgery, an exophytic chiasmatic tumour was encountered, with an appearance similar to a glioma. The pathological appearance was consistent with the primary neoplasm in the breast.
