1- CEREBELLUM(NOTE THAT WE ARE AT THE

LEVEL OF THE SKULL BASE SO WE ARE INFRA TENTORIAL , THAT’S WHY WE SEE CEREBELLUM)

2- TEMPORAL HORN OF LATERAL VENTRICLE (BLACK SLIT GREEN ARROW)

3- SUPER SELLAR REGION (BLACK)

4- DORSUM SELLAE (WHITE)

SKULL BASE CT

1- SYLVIAN FISSURE 2- ANTERIOR HORN

OF LATERAL VENTRICLE

3- 4TH VENTRICLE

4- WHITE MATTER (DARKER)

5- GREY MATTER (LIGHTER)

1- choroid plexus ( note it appears grey

inside the black ventricle)

1- quadrigeminal (or supra-cerebellar cistern)

2- Folia of cerebellum (note the black lines)

3- sylvian fissure

4- 3rd ventricle

Note : around the 3rd ventricle there is Hypodensity (Dark) this is the Thalamus

1- posterior horn of lateral ventricle.

2- Sulcus (black due to CSF)

3- Gyrus ( grey)

1- this is the MCA ( Middle cerebral artery

as seen on CT enhanced contrast study)

Note : there are 2 small white Dots (Green arrow)

this is the Anterior cerebral artery (ACA) , communicating with middle cerebral artery

1- Straight sinus (venous) as seen on CT enhanced contrast study

Interventricular hemorrhage

1- bleeding inside ventricle

2- bleeding in the Brain Parenchyma

Diffuse axonal injury

You must know how cerebral edema looks.

Brain herniation is not important. You must know ventricles, sulci, gyri,

grey matter , white matter, Basal ganglia
