The authors presented a case of fracture and dislocation at odontoid base in 3 year old patient. This fracture and dislocation was successfully treated by the Gardner's tong traction followed by Halovest application. We also reviewed the characteristics, treatment and prognosis of the pediatric odontoid process fracture.

Thirty three cases with agenesis of the corpus callosum were reviewed from the base of brain CT findings for last 7 years. Clinical features, associated clinical anomalies and CT findings were also analysed and the embryological basis for agenesis of the corpus callosum were reviewed from the literature.

Authors analyzed 40 patients diagnosed as and treated for aneurysmal subarachnoid hemorrhage or unruptured aneurysm at the Yonsei University Hospital from July 1 to September 30, 1986, prospectively. Result of the analysis is summarized as follows; 1) Ocular motor palsy or gaze palsy was found in 19 patients (47.5% of the total). Thirteen patients had ocular-motor palsy; 6 oculomotor nerve palsy, 5 abducens nerve palsy, 2 oculomotor and abducens palsy. Six patients had gaze palsy; 3 impaired conjugation, 2 upward gaze limitation, and I conjugated deviation. 2) Most of oculomotor palsies were resulted from direct pressure of IC-Pcom aneurysm on the oculomotor nerve. One incomplete oculomotor palsy might be caused by cerebral vasospasm. Oculomotor nerve palsy recovered in following order; ptosis, limitation of ocular movements, impairment of pupillary constriction. 3) Abducens nerve palsy could be explained by raised intracranial pressure. Vasospasm was also speculated as a possible cause of abducens palsy when other causes were excluded. 4) Incidence of clinical vasospasm increased in proportion to amount of sudarachnoid hemorrhage in the basal cisterns detected on CT scans. 5) Gaze palsy may indicate a grave prognosis, because five out of six patients with gaze palsy eventually died. Impaired conjugation was thought to be resulted from brain stem ischemia, secondary to raised intracranial pressure or vasospasm. Hydrocephalus caused upward gaze limitation, while frontal lobe hematoma produced conjugated deviation. 6) Abnormal ophthalmoscopic findings were found in 15 patients (37.5% of the total). Ten had retinal hemorrhage and five had papilledema.

Authors report four cases of hydrocephalic patients with slit ventricle syndrome, three of whom evidenced reexpansion of the ventricular system following insertion of high resistance valve or anti-siphon devices. The results of the treatment were dramatic in two cases of anti-siphon divice application and relatively good in one case of high resistance valve application. The authors reviewed the pathogenesis, diagnosis and treatment of the slit ventricle syndrome.

A case of cervicothoracic intramedullary glioblastoma multiforme associated with syringomyelia is reported. The tumor was located between C5 and T1 level and a large syrinx was found below the tumor, T1-T12. Intramedullary uptake of contrast dye in the delayed CT scan after myelography was seen. The tumor was removed gross totally. And terminal syringotomy was performed.

The intraphepatic migration of a distal ventriculoperitoneal shunt tube(Accu-flo shunt system medium pressure) is reported. This is rare complication of ventriculoperitoneal shunt, which was diagnosed by abdominal computed tomography. To our knowledge, this is the third reproted case complicated with migration of a peritoneal shunt tube into the liver.
