  • Title: [A case of lumbar myxopapillary ependymoma discovered due to headache].

    Abstract:
    A 23-year-old man was admitted to our hospital with lumbago about two weeks previously, and headache six days previously. Brain MR imaging revealed no remarkable findings except for left ethmoid sinusitis; both MR angiography and venography showed no vascular abnormalities. On the day after admission, lumbar puncture was performed because right homonymous hemianopsia and nuchal stiffness developed. The cerebrospinal fluid appeared bloody, and the source of bleeding was searched for. MR images of the lumbar spine demonstrated an intradural tumor with heterogenous contrast enhancement, and this tumor was considered to be the source of the bleeding. Tumor resection was performed, but some parts of the tumor could not be resected because of adhesion to the cauda equina. The pathological findings of the tumor demonstrated myxopapillary ependymoma. Radiation therapy was added to treat the residual tumor because myxopapillary ependymoma tended to recur in spite of the benign nature of the tumor. Spinal myxopapillary ependymoma is rare, but it causes subarachnoid hemorrhage. Subarachnoid hemorrhage from spinal tumor should be suspected when headache accompanied with severe low back pain are present even in the absence of spinal signs.
