There is a small well defined infratentorial oval lesion in the left quadrigeminal cistern (perimesencephalic cistern), just above the left superior cerebellar peduncle. It appears markedly hyperintense T1W and slightly hypointense in T2W images, denoting fatty consistency, with hypointense component in both T1W and T2W images denoting calcification. It shows no contrast enhancement, no restricted diffusion in DW images
