Conclusion
A wide spectrum of lesions can affect the pineal gland and the adjacent structures.
Some of these have special features that allow easy identification with imaging,
while others have similar non-specific characteristics and are often completely overlapping.
In these cases,
it is useful to extend the MR examination to other segments,
perform more advanced sequences or integrate it with laboratory tests to add useful elements to narrow the field of the differential diagnosis.
Diffusion imaging is not of fundamental diagnostic support in most cases,
since only a few high cellular masses (pineoblastomas and germinomas) show a peculiar behavior in these sequences.
As far as spectroscopy is concerned,
further studies are needed to determine the effective power of differentiation between the various lesions examined.
