Long-term sequelae of herpes simplex virus encephalitis–related white matter injury: correlation of neuropsychological outcome and diffusion tensor imaging

Journal of NeuroVirology - The pathophysiology of the memory impairment following Herpes Simplex virus encephalitis is not yet established and understood. This study attempts to elucidate the role...     

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

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.
