Normal CPA

Findings:
No intra or extra-axial mass lesion or collection is identified. The ventricles and sulcal spaces are within normal limits. The midline structures are normal with no midline shift.
Partially confluent zones of T2/Flair hyperintensity involving the subcortical and periventricular cerebral white matter are noted, in keeping with mild left small vessel ischemic disease.
The brain parenchyma is otherwise unremarkable. No abnormal signal on the susceptibility weighted images or diffusion/ADC images is identified.
The vestibular-cochlear apparatus and internal acoustic canals have a normal appearance. No structural cochlear abnormalities.
The facial and vestibulocochlear nerves have a normal appearance, as well as the trigeminal and abducens nerves. No CPA mass lesion.
The pituitary gland is normal.
The orbits, paranasal sinuses and mastoid air cells are clear. No bony abnormality is seen.
