Background: In recent years, improvements in oncological care have led to an increased incidence of intradural extramedullary spinal metastases (IESMs) attributed to uterine carcinosarcoma (UCS). When such lesions occur, they typically carry a poor prognosis. Here, we have evaluated newer treatments, management strategies, and outcomes for IESM due to UCS.
Case description: A 59-year-old female with a history of recurrent UCS presented with the new onset of the left lower extremity pain, numbness, and episodic urinary incontinence. When the MR revealed an enhancing intradural extramedullary mass posterior to the L1 vertebral body, she underwent a focal decompressive laminectomy. Although she improved neurologically postoperatively, she succumbed to the leptomeningeal spread of her disease within 2 postoperative months.
Conclusion: Management of IESM due to UCS requires multifaceted, individualized treatment modalities, including neurosurgery, radiation therapy, and medical oncologic management to maximize outcomes.
