Central Cord S e.g. syringomyelia, neck trauma..
loss of motion and sensation in arms and hands (brachiofacial)
Dandy Walker
- congen. no medial/lat apertures
- large 4th ventriccle, small cerebellum
- developmental delay, poor tone/balance/coordination
- jerky eye movements, vision/hearing impairments
- seizures
Arnold Chiari malformation
posterior fossa contents in cervical spine
can have downbeat nystagmus
Anterior Chord s.
ischemia of ant spinal artery/artery of adamkiewicz
- complete motor paraysis
- loss of pain/temp sensation distal to lesion
Talk and Die s
- pterion fracture, ruptured MMA
- extradural haemotoma
Recurrent artery of heubner stroke (distal part of medial striate artery off ACA)
disrupts ant limb of internal capsule supply
- contra brachiofacial weakness
- chorea
Ant Choroidal artery s.
Damages int capsule, thalamus, optic chiasm…
- contra brachiofacial weakness
- contra hemianopia
- contra hemianaesthesia
Anton’s / Visual Anosognosia
Bilateral occipital lobe damage
- cortical blindness
- pateint adamant they can see
Neglect s.
- right parietal lesion
- hemispatial neglect, hemiinattention
- (+/- anosognosia)
Trigeminal neuralgia / Tic Doloureux e.g. tumour, MS, blood vessels pressing on root…
- lancinating pain in CNV teritorry
- the suicide disease
Bell’s Palsy
- swollen/compressed CNVII e.g. herpes zoster
- LMN facial paralysis, no sparing
- crocodile tears, aberant reinervation lacrimal/salivary glands
