case_images: (a and b) T1 weighted MRI scans reveals homogenous intensely hyperintense lesion in the quadrigeminal cistern (arrow), pushing the midbrain anteriorly; (c and d) suppression of the lesion (arrow) on fat saturation sequence, suggesting presence of adipose tissue

case_images: T1 weighted magnetic resonance imaging (MRI) showed a 33 x 22 x 26 mm hyperintense lesion in the quadrigeminal cistern, displacing the midbrain anteriorly [Figure 1a and b]. The lesion revealed suppression on fat saturation sequences [Figure 1c and d], suggesting the presence of adipose tissue.
case_images: (a) T2 weighted sagittal MRI reveals homogenously hyperintense lesion occupying the quadrigeminal cistern (arrow); (b) Post operative T1 weighted MRI showing a small residual lesion (arrow); path of the surgical approach is visible as hyperintensity (vacant arrow), representing reactive gliosis

case_images: The pressure on the midbrain was relieved, and a tiny residual tumor mass [Figure 2a and b] in close proximity to the superior cerebellar artery was left behind.

case_images: Smears stained by Toluidine blue and rapid Hematoxylin and Eosin (H and E) revealed lobules of fibroadipose tissue admixed with few blood vessels [Figures 3 and 4].

case_images: The histology sections corroborated with the squash smears, bearing similar lobules of adipose tissue intimately admixed with fibrocollagenous tissue, blood vessels and gliotic white matter [Figure 5].
