Isolated dural metastasis in breast cancer after 22 years and approach to its management

Abstract

Breast cancers are the second most common cause of intracranial metastasis, after lung cancer, mostly occurring in brain parenchyma. However, dural metastasis (DM) is a rare site representing only < 1% of all metastasis in breast cancers. Median age of occurrence of DM is after 2–3 years of primary diagnosis. DM is usually associated with other skeletal metastasis and isolated DM in a treated case of breast carcinoma is rarer. We report a case of DM in a 67-year-old female patient previously treated for breast cancer 22 years back. The patient underwent surgical excision for DM followed by whole brain radiation and is on palliative chemotherapy.
