title: Clival chordoma manifesting as nasal bleeding. A case report.
abstract: Chordoma is a rare cartilaginous tumor, for which bleeding presentation is unusual. We report a case of rare hemorrhaged clival chordoma, which was diagnosed correctly by magnetic resonance imaging. A 32-year-old man presented with nasal bleeding. The tumor was totally removed via a trans-sphenoidal approach, from which the surgical specimen confirmed chordoma. Epistaxis seemed to be caused by the spreading of the intratumoral hemorrhage into the sphenoid sinus. This case demonstrates the importance of an exact differential diagnostic evaluation, including chordoma, by use of modern imaging techniques for nasal bleeding.
