Crescent-shaped extra-axial esion capping the posteroinferior aspect of the quadrigeminal plate is noted insinuating itself in-between the quadrigeminal plate of the mid-brain anteriorly and the superior vermis of the cerebellum posteriorly. It is measuring 4 x 11.5 x 11 mm in AP, TS and CC dimensions respectively.
It showed marked T1 pre-contrast high signals and T2 high signals as well with complete suppression on fat-suppressed sequences. Evident blooming in SWI noted.
The lesion is exerting mild indentation of the inferior colliculus of the tectum of the midbrain and to a lesser extent the superior colliculus (Auditory and visual complaints could be explained).
No restricted diffusion or surrounding oedema.
