Intradural Extra medullary Spinal Metastasis From Breast Carcinoma: A Rare Occurrence

Intradural extra medullary (IDEM) metastases are uncommon spinal lesions, accounting for less than 5% of all spinal metastases (1). Breast carcinoma is among the most frequently reported primaries. Because of their rarity and nonspecific imaging features, the diagnosis remains challenging due to imaging overlap with benign intradural tumors. Management is mainly palliative, combining surgical decompression and or radiotherapy, with systemic therapy as indicated. Prognosis remains poor, but prompt recognition can improve quality of life and functional outcomes. We report the case of a woman with a history of breast carcinoma under oncologic follow-up who developed neurological symptoms. Spinal MRI revealed an intradural extra medullary lesion. Surgical resection was performed for decompression and histopathological analysis confirmed metastatic breast carcinoma.
