Intradural prepontine growth: Giant ecchordosis physaliphora or extraosseous chordoma?

Abstract

An unusual case of a 54‐year‐old woman who presented with a one‐and‐a‐half year history of dizziness and in whom neuroimaging studies revealed an intradural prepontine growth without radiological evidence of bone involvement, is reported. A marked histological resemblance to both ecchordosis physaliphora and chordoma was observed. The medical literature concerning similar lesions is reviewed.
