On this lateral view R ICA injection, name these two branches:

Pericallosal and callosomarginal arteries off the ACA

100

Name the highlighted artery

Posterior Inferior Cerebellar Artery (PICA)

100

Name the three major branches off the aortic arch, as seen on this axial CTA:

A patient presents with right-sided sensory loss and fluent aphasia. Classically, which territory is likely affected?

A) L MCA, superior division

B) L MCA, inferior division

C) L ACA, pericallosal branch

D) L ICA, anterior choroidal branch

B) L MCA, inferior division

On the venous phase of this lateral L ICA injection, name the superficial vein:



200

Name this segment of the ICA: 

Petrous segment


200

On this AP view right vertebral artery injection, name the following vessel(s):

Superior cerebellar arteries (duplicated SCA)

200

On this lateral view L ECA injection, name the vessel at the white arrow, which is the route of collateral between the ECA and ICA (yellow arrow) in this patient with longstanding ICA occlusion.

White arrow is the Ophthalmic artery-- here, likely collaterals from the ECA (through the internal maxillary artery --> ethmoidal artery) collateralize with the ICA through retrograde filling of the Ophthalmic

Strokes of the bilateral parietal lobes can lead to this syndrome characterized by optic ataxia, oculomotor apraxia, and simultagnosia.

Balint Syndrome

Optic ataxia is the lack of coordination between visual input and hand movements. For example, the patients can accurately touch their own body voluntarily, but when given a visually guided task, they are unable to complete it.

Oculomotor apraxia is the inability to voluntarily shift gaze despite the intact function of extraocular muscles.

Simultagnosia is the lack of ability to perceive more than a single object at a time. For example, when provided with a picture of a forest with trees, they are unable to see the forest, although they can see each individual tree

A patient presents with R eye down and out, unsteady gait, with L arm tremulous movements. Which midbrain syndrome is this? 

A) Weber

B) Benedikt

C)  Claude's

D) Nothnagel's
