Left cerebellopontine angle and right frontal convexity meningioma

Findings:
Avidly enhancing, extra-axial, left cerebellopontine angle mass centered on the petrous ridge with dural tail, measuring approximately 1.12 x 1 cm. The lesion extends to the posterior edge of the internal acoustic meatus, but does not enter the IAC. No contact to the 7th/8th nerves.
Also, well-defined, extra-axial mass measuring approximately 1 cm is seen arising from the convexity meninges of the right frontal lobe. The mass shows blooming artefacts on the susceptibility-weighted images and avid homogeneous enhancement on the postcontrast study. Hyperostosis of the adjacent frontal bone is also noted.

No evidence of any further intra or extra-axial mass lesions. The ventricles and sulcal spaces are within normal limits. The midline structures are normal with no midline shift.
The brain parenchyma is unremarkable. No diffusion restriction.
The pituitary gland is normal.

The orbits, paranasal sinuses and mastoid air cells are clear. The craniocervical junction is normal.

Conclusion:
MRI appearances of a small left cerebellopontine angle meningioma as well as a right frontal convexity meningioma, without any mass effect.
