An 83-year-old woman developed pituitary metastasis while being treated for metastatic breast cancer. She presented with visual disturbance and headache followed by thirst, nocturia and polyuria. A visual field defect was present. MRI revealed a sellar mass consistent with metastasis to the pituitary gland. She was successfully treated with radiotherapy to the sella and had improvement of her visual symptoms and visual field defect. She then required ongoing treatment for diabetes insipidus. Her symptoms had not shown any sign of recurring up to 9 months after treatment. Pituitary metastases are rare but should be suspected in patients with metastatic cancer who present with features similar to those seen here. With improvements in survival in metastatic breast cancer, pituitary metastases may be seen more commonly and active local treatment is warranted given the possibility of resolution of symptoms related to the pituitary metastases.
