Question: What does "There is mild diffuse cortical volume loss with compensatory
ventricular dilatation." mean?

This is the MRI report:
Narrative
Clinical indication : Unspecified visual disturbance the
MRI tech comments - "
PT C/O H/A'S H/O HYPOGONADISM

Comparisons: NONE.

Exam: MRI BRAIN WITHOUT CONTRAST

Findings: The brain parenchyma demonstrates normal signal intensity.

The major arterial and venous flow voids appear normal.

There is mild diffuse cortical volume loss with compensatory
ventricular dilatation.

The visualized internal auditory canals are unremarkable.

There is extensive polypoid mucosal thickening (with suggestion of
superimposed retention cysts/polyps) identified in the right
maxillary sinus and a small nodular focus of T2 hypointensity noted
inferiorly.

There is trace opacification in the mastoid air cells.

The visualized parotid glands are negative.

The visualized TMJs are located bilaterally.

The visualized globes and orbital contents are negative.

The cranio-cervical junction is normal.

Incidental note is made of a partially empty sella configuration.

Impression
IMPRESSION:

1. There is extensive polypoid mucosal thickening identified in the
right maxillary sinus, as detailed above. Clinical correlation is
advised as these findings may correspond to the patient's symptoms of
headaches.

If there is strong clinical concern to further evaluate the paranasal
sinuses for disease - a dedicated (outpatient elective) CT of the
Sinuses may be of further benefit.

2. Otherwise , the remainder of the examination is largely
unremarkable - there is NO acute infarction, acute intracranial
hemorrhage, intraparenchymal masses, mass effect, nor abnormal
extra-axial fluid collections.

3. There are other chronic and incidental findings as detailed above.
