Eight patients with gross lesions of the pons as demonstrated by air contrast study as well as cranial nerve, long tract and cerebellar syrnphomatology, were treated with 240 kilovolt x-ray therapy, .receiving 2,750 to 5,000 r. initial dose with palliamon for most of them, Another 2,750 to 5,000 r. Intial does palliation for most of them. Another child received only 600 r. and was not helped. ,'(, Given Iran, There 'are two survdvors, one asymptomatic in ten years, having a child, and one who .recurred at six and a half years and has received further palliation additional x-ray therapy. With initial palliation of six months or more, a second course of x-ray therapy has given rurt her palliation is three cases even though the ultimate outcomem was fatal.

22 cases submitted to sub-total hemispherectomy are discussed. In selected group of infantile hemiplegia where epilepsy and behavior disturbances are present, and investigations prove that the other hemisphere is normal, this operation is of great benefit. Nevertheless long follow-up of these cases is necessary pefor"O a final judgement can be passed, Age should-be no barrier to selection, as those of 18 - 25 have benefited as much as young chlidren. Post-operatively there has been no diminution of movements of the ~ffected side. This has been explained on the basis of recent experiments and observation on the motor function of cerebral cortex,

100 cases of extradural spinal compression comprising 74% of all cases of spinal compression were included. Ver-tebral and extravertebral compression occurred with equal frequency.
1. Most of tJhe cases occurred between 20-50 years of age, with no significant dif'fe'rerlce1s between various causes, except in vertebral hemangioma which tend o affect the younger age groups (10-20). Males were commonly affected.
2. The dorsal region was the' commonest site encountered.
3. All patients showed the picture of progressive paraplegia with a sensory level. The initial symptom was pain, root or local pain, in almost two-thirds of the patients. Tenderness over the spine favoured the diagnosis of a vertebral lesion or an inflammatory condition.
4. Vertebral lesions were usually evident on plain radiography
5. Myelographic diagnosis was found to be more accurate in the cervical and dorsal regions (85%) than in the lumbar region.
6. Pott's paraplegua formed 20% of the cases. Lamincetomy in these cases mostly mid-dorsal was thought to giv.e a better access for decompression in the cord, rather than costotransversectomy or antero lateral decompression.
7. Operation followed by irradiation was thought to be a better treatment than irradiation alone.
8. Chondromas were found to have a tendency to recur. It is thought that was due to 'incomplete removal rather than due to malignant transformation.
9. Vertebral lesions, suspected to be secondary deposits, with no apparent primary focus, were explored for decompression and verification.
10. Decompression of the cord in cases of dorsal disc prolapse was found to a safer procedure.
11. Two cases of localised extradural abscess secondry to lumbar puncture encountered.
12. Elxtr-adural angioma and angio-endothelicma comprised 14%. Partial or complete excision followed by irradiation gave satisfactory result.
13. More than half the cases of extradural neurofibromas had extra spinal -

Carotid gamma angiography completes the advantage of paraclinic investiga - tions in field of neuroradiology.
Since this procedure can easily proceed the regular contrast angiography, it furnishes additional valuable data without being additionally traumatizing to the patient.
Informations obtained by gamma angiography give important indications on the cerebral circulatory dynamics and in fact becomes a valuable method.
Sometimes, the forms of curves obtained by this method would be sufficient to make the diagnosis of brain circulatory insufficiency and avoid to inject dye , wich in these cases is not without danger.
