title: Breast cancer metastasis to the pituitary gland.
abstract: Metastatic tumors to the pituitary gland are an unusual complication typically seen in elderly patients with diffuse malignant disease. Breast and lung are the commonest sites of the primary tumor. Prognosis of patients with breast cancer metastasis is poor and depends on the primary neoplastic extension. We report a 54 year-old woman with breast cancer metastasis to the pituitary stalk first diagnosed because of visual disturbance with no other symptoms. Pituitary gland stalk metastasis is a very uncommon find and this case report includes a literature review.
