[Subarachnoid haemorrhage from an ependymoma of the filum terminale. (author's transl)].

The case of a patient suffering from acute lumbosciatic pain, flaccid paraplegia, bladder retention and subarachnoid hemorrage, is reported. The patient underwent operation for a large ependymoma of the filum terminale. The author underlines the rare association of a spinal cord tumour and subarachnoid hemorrage and the opportunity of a routine mielo-radiculographic examination in case of lumbo-sciatic pain requiring surgical intervention: the patient, in fact, had been operated for "lumbar disc prolapse", in an orthopaedic department, four years before.
