Chordoid glioma of the third ventricle: report of a rapidly progressive case.
Chordoid gliomas are slowly growing third ventricular tumors that can be challenging to manage clinically. Rapid progression causing death has not been previously reported for this tumor type. We present and discuss a case of chordoid glioma that arose in a 46-year-old female who presented with progressive fatigue, headache, and altered mental status, attributable to severe hydrocephalus caused by a third ventricular mass. She underwent urgent subtotal resection and ventriculo-peritoneal shunt placements. Post-operative MRI noted residual tumor in the anterior resection cavity. An MRI performed 9 weeks later showed substantial progression, with marked tumor enlargement and compression of adjacent hypothalamic structures and the optic chiasm. Despite a course of radiation therapy, the tumor continued to enlarge, and the patient died from tumor progression 7 months after initial presentation. Post-mortem exam demonstrated a mass that expanded the third ventricle and compressed adjacent hypothalamic, thalamic and suprasellar structures. Histologic and immunohistochemical studies confirmed a chordoid glioma and revealed multifocal coagulative necrosis and intravascular thrombosis, which are unusual in this tumor type. Cytogenomic microarray testing revealed numerous DNA copy number abnormalities, many of which had not previously been reported in this tumor. The pathologic and cytogenetic changes may correlate with the aggressive behavior of this chordoid glioma and can be pursued by future investigation of additional cases.
