There is a 10mm x 6mm x 8mm cyst-like mass lesion within the left amygdala. The lesion within the left amygdala does not demonstrate contrast enhancement, increased perfusion or restricted diffusion, but does have partial T2 suppression on flair with a residual bright rim of signal. Spectroscopy demonstrates mildly decreased NAA, increased Cho and raised Myo-Ins within the lesion. The mass lesion impresses upon and flattens the left hippocampal head, however, the internal architecture and signal of the left hippocampal body and tail is preserved. There is loss of grey-white matter differentiation along the left para-hippocampal gyrus - this may be seizure-related or as a result of associated cortical dysplasia.
The right hippocampus has normal signal and internal architecture.No remote intra- or extra-axial mass lesions, acute haemorrhages or collections.
No regions of abnormal supra- or infra-tentorial suscepability blooming. No regions of abnormal parenchymal or meningeal enhancement.
There is a mass lesion within the left amygdala with impression on the left hippocampal head.
The body and tail of the left hippocampus has normal signal and internal architecture, however, there is loss of grey-white matter definition within the adjacent left para-hippocampal gyrus that may be secondary to associated cortical dysplasia.
The left amygdala lesion most likely represents a DNET or a low grade glial series tumour - the spectroscopy trace favours low grade glial series tumour.
