title: A unique presentation of retroclival chordoma.
abstract: Chordomas are rare tumours which arise from remnants of the primitive notochord. They occur primarily in the sacrum, clivus and cervical regions. We report a case of retroclival chordoma which presented as an extradural haemorrhage following minor trauma. The underlying tumour was not apparent on imaging performed immediately following the event, and chordoma presenting in this manner has not previously been described in the literature. The tumour became apparent on subsequent imaging, and progressed despite surgical debulking and radiotherapy.
