Section 215

1.What clinical tests can be done to determine dissociative sensory loss?

2.what is the recommended dose of urograffin before performing contrastenhanced computed tomography? How far in advance should this be

administered before imaging when an intracerebral abscess or glial

tumour is suspected?

3.How many urografin ampoules (76% concentration) should be

administered before a CT brain scan with contrast searching for a mass

lesion, and how many minutes before imaging should these be injected?

4. What is the difference between fluid-attenuated inversion recovery

(FLAIR) and T2-weighted MRI scans?

b. What is the advantage of magnetization transfer pulse over a FLAIR

MRI scan?

5.Does lumbosacral MRI refer to lumbosacral spines or to lumbosacral cord

segments?

Section 2155

1.If a young patient who has suffered a stroke has a normal mental state,

would this exclude a cerebral venous occlusion as an aetiology?

2.Does persistent hiccough following cerebrovascular ischaemic stroke

localize to the medulla or to any other site?

3.By what mechanism is vertebrobasilar insufficiency associated with

circumoral numbness?

4.Why does lateral medullary syndrome result in ipsilateral diplopia due

to cranial nerve VI?

5.I have seen many established ischaemic stroke patients with CTdocumented capsular infarction and hemi-hypotonia despite exaggerated

reflexes. How would you explain the hypotonia? Could it be due to a

corticorubral fibre lesion?
