Learning objectives
To clarify the functional anatomy of the nuclei and complex pathways of the brainstem and to understand why a certain pathology in a certain location gives a specific neurological deficit.
To learn about more advanced MR techniques as DTI (Diffusion tensor imaging)
Background
The brainstem contains numerous pathways and nucleii,
all organised in a small area.
Also the presenting neurological features can be challenging to localise.
Knowledge of the anatomy of different tracts,
nucleii and vascularisation as well as recognising specific diseases,
is mandatory in order to assess these complex cases.
Findings and procedure details
Anatomy/ Embryology
Every cell in the human body originated from either endoderm,
ectoderm or mesoderm.
These are primitive germ cell layers,
which become established by the second week of human embryonic development.
By the third week two paralel folds begin to develop in the outer ectoderm,
with a neural groove between them.
Eventually this will form a neural tube halfway the fourth week.
From the fourth to the eighth week different brain vesicles develop,
each giving rise to different parts of the central nervous system....
Conclusion
We reviewed the most important tracts and nuclei of the brainstem and what deficit we can expect from a lesion in a certain location.
