A 63-year-old man presented with rapidly progressive visual field deficit and hypopituitarism including diabetes insipidus, 8 years after treatment for a renal cell carcinoma. Neuroimaging studies revealed a dumbbell-shaped pituitary mass that had destroyed the sellar floor and abutted against the optic apparatus. Fractionated stereotactic radiotherapy (SRT), employing computer-image integration techniques and a frame that could be relocated to facilitate a fractionated dosing scheme, was carried out under a plan for reducing the treatment risk to the optic apparatus. Three months later, the patient exhibited marked improvement in the visual field deficit and visual acuity concomitant with a reduction in tumor volume. Magnetic resonance imaging of the sellar region confirmed striking shrinkage of the metastasis. His neurological status remained stable at 12 months after the SRT with no complications. Fractionated SRT appears to be effective for preserving or improving the residual vision in patients with visual loss secondary to metastatic tumor of the pituitary gland, and may result in a longer and better quality of life.
