The rare but correct diagnosis of a clival chordoma which had invaded the brain stem and subsequently hemorrhaged was based on computed tomography and magnetic resonance imaging. The diagnosis was confirmed at surgery when the patient underwent a successful operative decompression of tumor and clot from the pons via a sub-occipital craniotomy. This represents the first case of a clival chordoma to hemorrhage into the brain stem, which was diagnosed preoperatively and the patient survived.<\/jats:p>","DOI":"10.1017\/s0317167100032273","type":"journal-article","created":{"date-parts":[[2016,7,28]],"date-time":"2016-07-28T11:42:00Z","timestamp":1469706120000},"page":"515-518","source":"Crossref","is-referenced-by-count":13,"title":["Clival
