IV-enhanced MRI with MR spectroscopy shows:
A rather sizable well defined mass, originating from the tuber cinereum, exhibiting homogenous isointense signal to the grey matter in T1 and T2, and shows no significant enhancement in the post contrast study.
In MR spectroscopy, there is elevation of the Cho levels with reversal of the NAA/Cho ratio.
Those MRI criteria are highly suggestive of tuber cinereum hamartoma.
