Abstract
A 34-year-old female, who had history of treatment for breast cancer 4 years ago, presented with urinary retention and paresthesia of both lower limbs. The patient was treated with upfront (primary); Linac-based (Shaped-beam) SRS for L1–L2 intradural, intramedullary, solitary spinal cord (conus medullaris) metastasis from breast carcinoma. The target volume of 0.15 cc received a marginal dose of 14.0 Gy normalized to 90% isodose line. At 6 months post-SRS, the patient had resolved urinary retention and improved paresthesia. At 9 months post-SRS, the patient had normal urination and improved lower limbs paresthesia and was neurologically intact. Follow-up MRI showed complete disappearance of conus medullaris tumor. Continued clinical and radiological follow-up was advised.
