Which brain structure does the vascular lesion in Pot 3 originate from?
Right lentiform nucleus
Is the internal capsule affected by the lesion in Pot 3?
Yes, there is minimal compression of the internal capsule
Which ventricle is compressed in Pot 3?
Right anterior horn of the lateral ventricle
Where is the origin of the haematoma in Pot 4?
Right lentiform nucleus, probably in the putamen or external capsule

Relay sensory information to the cerebral cortex
Which structure is being compressed in the roof of the ventricle?
Corpus callosum
Can you identify the right lateral ventricle?
Yes, it is difficult to identify due to compression by the meningioma.
