T1 Hyperintense Prepontine Mass with Restricted Diffusion--A White Epidermoid or a Neuroenteric Cyst?

J Neuroimaging. 2015 Sep-Oct;25(5):841-3. doi: 10.1111/jon.12226. Epub 2015 Feb 16.

Abstract

Neuroenteric cysts (NC) are benign, congenital malformation which are of endodermal origin commonly located in the central nervous system. We report a case of intracranial NC with squamous metaplasia and xanthogranulomatous response masquerading as a white epidermoid on conventional MRI sequences. Lesion showed two components on T2W-images. We observed differential diffusion characteristics including fractional anisotropy, radial diffusivity and axial diffusivity within the two components of the lesion.

Keywords: Neuroenteric cyst; anisotropy; diffusivity; magnetic resonance imaging; squamous metaplasia; xanthogranulomatous response.
