title: Myxopapillary ependymoma of the conus medullaris with subarachnoid haemorrhage: MRI in two cases.
abstract: Subarachnoid haemorrhage due to cauda equina tumour is rare. We report two myxopapillary ependymomas of the conus terminalis, presenting with in this way. Rims of low signal were observed at their upper and lower borders, mainly on T2-weighted images. This finding has been described in ependymomas of the cervical region but not, to our knowledge, in myxopapillary ependymomas of the conus terminalis.
