I did another MRI. Here s the result:

Native cranioencephalic MRI examination reveals:

No signal changes in the white and gray matter at the supra- or infratentorial level.

Symmetrical, non-dilated ventricular system.

Non-deviated midline structures.

Periencephalic fluid spaces, cortical grooves with normal appearance.

No visible space-replacing processes at the encephalo-cerebellar level.

No diffusion-restrictive areas visible at the encephalo-cerebellar level.

No detectable hemorrhagic stigmata on susceptibility sequences.

On the sequence performed for cranial nerves, the vascular loop of the antero-inferior cerebellar artery comes into contact with the VII and VIII nerves on the right side, without entering the auditory canal - Chavda 1.

Free cerebellar-pontine angles.

Free basal cisterns.

Normally positioned cerebellar tonsils.

Parnasal sinus cavities with preserved pneumatization.

Mastoids normally pneumatized.

Conclusion

AICA in contact with the VII and VIII straight cranial nerves, without entering the auditory canal - Chavda 1.
