Objective: To report a case of a giant ecchordosis physaliphora causing local bone remodelling.Patients: A 45 year old man, who presented with sudden sensorineural hearing loss.Intervention: Transpetrosal approach to resect a midline prepontine mass.Main Outcome Measures: Radiological and histological findings.Conclusion: The distinction between giant ecchordosis physaliphora and intradural chordoma is questioned and exemplified by our case. It is possible they represent the same entity of disease, which must be distinguished from classical malignant osseous (extradural) chordoma.
