The case is reported of a 2 l/2-year-old femal with headache, vomiting and paraparesis. Clinical feature and operative finding's are quite different from those of classic medulloblastoma in its lateral location, well-circumscribed tendency, non-invasiveness, no CSF metastasis, and favourable prognosis after surgical removal. Histological features are the combination of those of classic, and desmoplastic medulloblastoma. Review of literature was done.

A case of huge craniopharyngioma which was removed radically is presented. A 14-year-old girl was hospitalized because of the impairment of vision and a history of generalized seizures. The computer tomogram of the brain disclosed the huge mass consisting of a large cystic part extending to the frontal base and solid part medial and posterior to the cystic. Despite of the large size and adhesion to the vital structures, the tumor was removed successfully with the aid of the operating microscope. The cystic part was aspirated first and then the deflated tumor dissected carefully. To remove the tumor radically, it seemed to be important not to interrupt the outer structure of the mass during dissection. The postoperative course was uneventful except transient diabetes insipidus. We report this case with brief review of the references.

Benign Schwannoma rarely involves the vertebral bodies extensively. Two eases of wide-spread involvement of -cervical vertebral bodies by Schwannoma are reported. Despite of huge amount of neoplastic mass and severe destructive bony changes, the neurologic deficits were minimal and postoperative result was-not discouraging. Finding of plain X-rays, cervical CT scan and tumor pathology were discussed: as well as surgical approach.

The occurrence of fistulous tract between the thoracic subarachnoid space and the pleural cavity due to injury is uncommon. The one was developed after traffic accident and treated by surgical repair of the fistula. The other was post-operative complication of costotransversectomy for T2 sympathectomy. The complication was realized by the surgeon who was aware of the small leakage of cerebrospinal fluid from the dura propria of the T2 nerve root at the time of surgery. Intermittent pleural punctures for drainage and semisitting position were followed by spontaneous closure of the fistula. These cases were reported so that the uncommon condition might be added to the differential diagnosis of pleural effusion.

The ventriculoatial shunt consists of diverting the cerebrospinal fluid from one lateral ventricle to the right atrium of the heart by means of a subcutaneous valve regulated drainage system. Of the numerous drainage systems so far devised, two, Holter and Pudenz, can be cited as having received widespread acceptance. This study is a clinical investigation of the 18 cases of ventriculoatrial shunts performed at Hanyang University Hospital between May 1972 and December 1978. Of them 17 cases and the Holter System, and one the Pudenz System. Ventricular catheter, tip was placed in the frontal, horn and cardiac catheter tip in the upper margin of the 6th thoracic vertebra. Postoperatively immediate neurological improvement usually took place in. most instances. However, four complications developed. One of them was ventricular catheter obstuction with small brain tissue particles which was removed by revision. The other ventricular catheter obstruction was the result of thickening of the cerebral mantle and reduction in size of the ventricle. This shunt was made patent again byshortening the ventricular catheter to place inside the shrunk ventricle. The third was shunt infection. In this case, the whole shunting system was removed and reapplied into a peritoneal route, after infection subsided. The last was postoperative epidural hematoma developed, due to incomplete hemostasis which required emergency surgery. Shunt obstruction was said as an inevitable complication in many instances, but it may easily restored by revision. Shunt infection was also surgically amenable. Although the necessity of revision, was inevitable in some instances, ventriculoatrial shunt still seemed to be the most effective method so far devised.
