While hyperintensity is seen in medial thalamic and periacuaductal gray matter on T2 and FLAIR sequences of cranial Magnetic Resonance Imaging (MRI) in acute cases, atrophy in mamillary bodies, enhanced signaling in the base of fourth ventricle, midline of cerebellum may be seen in chronic cases and contrast enhancement may occur in mamillary bodies and inferior quadrigeminal region (4,5).
