Objective : The results of secondary transsphenoidal surgery(TSS) for either residual or recurring pituitary adenomas have been reported to be unfavorable. To evaluate the effectiveness of secondary TSS, we analyzed the surgical results of residual or recurred pituitary adenomas in patients who underwent secondary TSS from 1992 to 1998. Material and Methods : Among the 95 patients who underwent TSS during this period, 14(15%) received repeated TSS. Two of the 14 patients underwent three TSS. Among the 11 patients with pituitary adenomas, three had nonfunctioning tumors ; six prolachnomas ; two GH-secreting adenomas. The remaining three patieats had craniopharyngioma, pituitary abscess and hemangioendothelioma respectively. The interval between the two surgical procedures ranged from one week to 33 months(mean ; 12 months). Causes of the secondary TSS were tumor recurrence in 11 patients, intentional staged operation in three, persistent disease despite medical therapy and CSF leak after initial operation in one respectively. Treatments prior to secondary TSS were medical treatment only in eight patients. Results : During the repeated operationtss some adhesion was noted in septal mucous membrane. The sphenoid cavity was filled with fibrous tissue which correlated with the methods of reconstruction of the sellar floor at the previous operation. There was no statistically significant difference in success rate of surgery between the initial and the second TSS(86% vs 81%). The complication rate was similar between the two procedures. There was no statistically significant factors affecting the results of second TSS. Conclusion : Transsphenoidal reoperation was regarded as a suitable approach for treating recurrent pituitary adenomas in spite of some degree of operative difficulties. In patients with transsphenoidally resectable tumor residuals or recurrences confirmed by magnetic resonance imaging, remissions can be obtained with high probability, especially in secondary surgery after an staged decompression.

7세 소아에서의 낭성수막종 : 증례 보고 Case Report

고영초,김현집,최길수,지제근 대한신경외과학회 1981 Journal of Korean neurosurgical society Vol.10 No.1

Gross cystic change and occurrence in childhood are both unusual for meningiomas. We present a case of cystic meningioma in a child with the characteristic CT findings. Possible pathologic clue for the cyst formation is also briefly discussed.

한국에 있어서의 뇌 기생충 질환의 전산화단층촬영 소견

고영초,심보성 대한신경외과학회 1980 Journal of Korean neurosurgical society Vol.9 No.1

Cerebral paragonimiasis and cerebra cysticercosis are two notorious parasitic infestations of the brain in Korea, of which diagnoses were not clarified yet clinically. The authors experienced 25 such parasitic brain disases with their characteristic CT findings, and it was assumed that computed tomography(CT scan) is the procedure of choice for the diagnosis of these parasitic brain diseases.

소아 제4뇌실에 발생한 "맥락총 유두종(Choroid Plexus Papilloma) 1예 보고

고영초,정희원,최길수,지제근 대한신경외과학회 1979 Journal of Korean neurosurgical society Vol.8 No.2

Papillomas of the choroid plexus constitute 3.4~3.9 percent of intracranial tumors in childhood, much higher incidence rate than that in adulthood. Although relatively rare, this is an important tumor since it is usually a benign resectable lesion with satisfactory result. It is also an unusually interesting tumor because of its association with a communicating hydrocephalus. Its site of occurrence is also characteristic according to the age, being usually lateral ventricle and rarely the 4th or 3rd ventricle in childhood. We present a case of 4th ventricle choroid plexus papilloma in a child with its characteristic CT finding.

천막상부 신경교종에서의 두부전산화단층촬영술 소견에 의한 조직병리학적 진단가능성에 관한 고찰

고영초,최길수 대한신경외과학회 1980 Journal of Korean neurosurgical society Vol.9 No.1

For assessment of the feasibility of histophathological diagnosis on the basis of CT findings in suratentorial gliomas, 60 consecutive histologically proven cases were anlaysed. Benign astrocytomas(Kernohan's grade Ⅰ, Ⅰ-Ⅱ, Ⅱ) were 25, Oligodendrogliomas 6, malignant gliomas(Kernohan's grade Ⅲ, Ⅲ-Ⅳ, GM) 29 in number. Plain CT findings and degree of peritumoral edema were less significant than the patterns of contrast enhancement in predicting the histological malignancy. Calcification, if present, excluded the diagnosis of malignant gliomas. Combining the CT criteria of pattern of contrast enhancement, degree of peritumoral edema with angiographic signs of malignancy in addition to the clinical feature, a more confident histological diagnosis seemed allowable.

종양내 출혈로 진단된 청신경 초종 -증례보고-

고영초 ( Young Cho Koh ),유헌 ( Heon Yoo ),권오기 ( O Ki Kwon ),김용만 ( Yong Man Kim ),주미 ( Mee Joo ),이기재 ( Ghi Jai Lee ) 대한뇌종양학회 2002 대한뇌종양학회지 Vol.1 No.1

The authors report unusual presentation of a vestibular schwannoma in a 53-year-old man, who presented with sudden onset of severe headache and, vomiting followed by left peripheral type facial palsy two weeks prior to admission. He had been well except for a longstanding left hearing difficulty, which had been considered as an aging process. In addition, he had mitral valve replacement surgery two years prior to admission , for which he had taken anticoagulant(Warfarin 2mg) everyday with regular monitoring of coagulability. Plain CT scan on admission demonstrated a 3×4×3cm sized high density mass at the left cerebellopontine angle with erosion and widening of the left internal auditory meatus. Brain MRI showed a heterogenous signaled mass with high signal on T1WI with little contrast enhancement and low signal on T2WI suggestive of multistaged hematomas within the peripherally enhancing tumor. Under the impression of intratumoral repeated bleeding in a patient with preexisting vestibular schwannoma, left suboccipital craniectomy was undergone to remove a large extraaxial tumor, mixed with large amount of hemorrhages. Postoperative course was uneventful except for persistent left facial palsy and hearing loss. Postoperative anticoagulation was started on the 5th postoperative day.

거대한 뇌수막류 수복후 두개골 재건술의 경험례

고영초,최병욱,서인석,하지운 大韓成形外科學會 1993 Archives of Plastic Surgery Vol.20 No.1

Encephalocele is defined as and "extracranial protrusion through a congenital opening in the skull. usually in the midline, of meninges, CSF, and/or cerebral parenchyma". The defect contatins only meninges and CSF or cerebral tissues as well, They can occur anywhere from the occiput to the nasofrontal region and are almost in the midline, Only rarely do they appear lateral to the sagittal plane. The authors experinced one case of encephalomeningocele and it was corrected by "Staged operation, the removal of encephalomeningocele, the V-P shunt operation and cranioplasty with calvarial bone graft and remodeling". After performing the staged operation we have followed the patient for about two years and the result was remarkably promising with normal development in speech, behavior, intellignce and physical status without any adverse neurologic sequelae.

안면부 Lymphangioma에 의한 Orbital Dystopia의 치험

고영초,정철현,방난석,하지운 大韓成形外科學會 1991 Archives of Plastic Surgery Vol.18 No.4

Vertical orbital dystopia is an abnormally low or high position of one orbit in comparison with the other side which is supposedly normal. The causes of vertical orbital dystopia include Congenital(craniosynostosis, hemifacial microsomia and facial clefting syndrome etc.), Trauma(orbital fracture and irradiation injury etc.), Neoplasms(fibrous dysplasia, antrum carcinoma, intracranial tumors, frontal and ethmoid sinus tumor and angiomatoses etc.) From the stand point of both visual function and asthetic aspects, the correction of vertical orbital dystopia is more difficult for the surgeon than in the case of equally great horizontal displacment. Uncorrected vertical orbital dystopia produce significant facial asymmetry and severe deformity than similar amount of horizontal deformity. The case of a 22 year - old female patient with vertical orbital dystopia associated with large cavernous lymphangioma on right forehead and supraorbital region is presented. The patient had aesthetically good result by correction of vertical orbital dystopia through intracranial approach in spite of impossible complete resection of cavernous lymphangioma.
