Symptomatic infundibulum metastasis from breast cancer and resolution of symptoms following Cyberknife® fractionated stereotactic radiotherapy: Case report

Abstract

While metastasis to the brain is a well known and common complication of breast cancer, metastatic spread to the pituitary gland, specifically to the area of infundibulum is a rare presentation. In symptomatic cases, the most common manifestation of an infundibular metastatic lesion is diabetes insipidus (DI). Management of lesions in this area is controversial. Here, we presented a patient with symptomatic solitary infundibulum metastasis originating from breast cancer and the results of fractionated stereotactic radiotherapy (FSRT). The tumor size regressed and her symptoms decreased after the delivery of FSRT. The patient died due to the progression of systemic disease seven months after the FSRT. © 2013 by Türkiye Klinikleri.
