Intramedullary metastases of MB are rare and there are very few cases reported in the literature. Here, we report the case of an 18-year-old man with intramedullary spinal cord metastasis of MB occurring 9 years after the first diagnosis. The patient presented a 2-month history of progressive weakness in both lower limbs associated with urinary incontinence. Magnetic resonance imaging (MRI) demonstrated a large intramedullary spinal cord tumor extending from T10 to L1. The patient underwent surgical decompression and adjuvant therapy. Histological examination confirmed the diagnosis of classic MB metastasis. Postoperatively, the neurological status was stationary. Intramedullary metastasis of medulloblastoma is rare and difficult to manage with a poor prognosis. Comprehensive studies on the medulloblastoma dissemination mechanisms and clinical trials are needed to assess combined therapeutic approaches on metastases of MB.展开更多

We present this disease. Case presentation: The patient was a 67-year-old woman with lung metastasis appearing 3 years after breast cancer surgery. Complete remission was achieved for the metastatic lesion with chemotherapy, but multiple cerebellar metastases were found 3 months after the completion of chemotherapy. Whole-brain irradiation was administered, resulting in symptomatic improvement. Approximately 6 months later, the patient experienced weakness in the lower extremities and difficulty walking. Magnetic resonance imaging detected a well-defined intraspinal tumor measuring 13 × 13 × 30 mm at the level of Th12-L1. After 20-Gy irradiation to the tumor, oral steroid administration, and rehabilitation, the patient regained the ability to walk. Eight months have passed, to date, since these interventions and the patient is currently receiving treatment for metastases to bones, including the spine, but is still capable of walking without difficulty. We herein report this case with a review of the relevant literature. Conclusion: ISCM in the breast cancer is relatively rare. But, it is the clinical condition which it should always place in the mind.展开更多
