[Recurrent subarachnoid haemorrhage with spinal neurinoma (author's transl)].

An unusual case of recurrent subarachnoid haemorrhage caused by a benign neurinoma in the region of the cauda equina is reported, in which the tumour was supplied by an accessory dilated artery. After recurrent complaints in the lumbar region an acute cerebral symptomatology first led to the diagnosis of a subarachnoid haemorrhage of unknown aetiology. It was only the recurrence of the bleeding which enabled the tumour to be detected. Other cases from the literature of subarachnoid haemorrhage due to spinal tumours are considered and the mechanism of bleeding and diagnostic problems are discussed.
