Solitary pituitary metastasis from breast cancer that presented as visual field defect

Abstract

Pituitary metastasis is an unusual event of cancer progression and breast cancer is the most common primary neoplasm metastasizing to the pituitary in the female population. Most patients who have developed pituitary metastasis were clinically asymptomatic. However, it is difficult to diagnose pituitary metastases due to the lack of specific symptomatology. We herein describe the presentation of one patient with symptomatic pituitary metastasis resulting from primary breast cancer. Subsequent to surgical intervention and loco-regional radiotherapy, the patient had a favorable outcome.
