차성숙 대한영상의학회 1982 대한영상의학회지 Vol.18 No.3

Various methods of taking of optic foramen view and avalabilities have been studied by many foreign ivestigators, but those in Korea have not been reported yet. The authors have measured and examined the size and shapes of optic foramina of optic foramen views in 111 Korean checked at Inje Medical College Hospital during about 3 years from June 1979 to March 1982. The cases were divided into two groups, A and B, for the convenience of study. Group A consisted of 50 normal Korea 5 to 55 years of age with no visual symptoms and signs. Group B included 69 patients 3 to 75 years of age with visual symptoms and signs. The results were as follows: 1. Mean value of actual diameter of optic foramen measured by Goalwin's method in Group A : Right : A diamenter ; 4.21mm, B diameter ; 4.32mm, Left : A diameter ; 4.29mm, B diameter ; 4.30mm. 2. Absolute symmetry of the greatest diameters of both optic foramina in Group A ; 36%, difference of 0.5 or less ; 28%, from 0.5 to 1.0mm ; 18%, from 1.0 to 1.5mm ; 8%, umcomparable cases ; 10%. The greatest difference was 1.4mm. 3. The shapes of optic foramen in Group A : oval shape ; 65%, circular ; 29%, keyhole or double foramen; 6%. 4. In Group B, the peak age group was second decade (31%), the most common clinical cause of examination of optic foramen view was optic nerve atrophy (30%), and the pathologic findings were only 4 cases (7%). 5. The technique of optic foramen view by modified Pfeiffer's method delineated the outline of optic foramen more clearly than ordinary Rhese's method in our experience.

차성숙,전제량 인제대학교 1998 仁濟醫學 Vol.19 No.2

직장 후방에 원발성으로 종괴가 발생하는 경우는 드물지만 다양한 질환이 생길 수 있다. 최근 5년간 부산백병원에서 수술로 확진된 직장 후방의 종괴 18예를 분석한 결과 양성 종양이 11예, 악성 종양이 4예, 그 외 농양이 2예, 혈종이 1예였고, 연령 분포는 1세부터 79세로 질환에 따라 차이가 많았으며 남녀의 비는 같았다. 각 질환의 CT 소견을 분석한 결과, 균일한 낭종으로 보이는 표피양낭이 5예였고, 낭종에 석회화 및 지방 조직을 동반한 기형종이 3예였으며, 낭성기형종 1예와 미소화관낭 1예는 균일한 낭종으로 보였고, 해면상 혈관종 1예는 경계가 좋지 않은 연조직 종괴로 보였다. 천골의 파괴와 석회화를 동반하는 척삭종이 2예였고, 석회화를 동반하지 않는 천골을 파괴시키는 거세포종양이 1예였으며, 평활근육종 1예는 경제가 좋은 연조직 종괴 내에 낭성 변성을 보였다. 그 외 낭성종괴가 조영제 주입 후 윤상조영증강을 보이는 농양이 2예였고, 석회화를 동반한 기질화된 혈종이 1예였다. CT는 종괴 자체를 직접 볼 수 있으며 구성 성분으로 병리조직학적 진단도 예측할 수 있으므로 직장 후방 종괴의 진단에 매우 유용한 검사로 생각된다. Purpose: To evaluate CT findings of masses in the rectrorectal space. Materials and Methods: The kinds, and CT findings of diseases in 18 pathologically confirmed cases of retrorectal masses(11 benign tumors. four malignant tumors. two abscesses, and one hematoma) were reviewed. Results: Well-defined homogeneous cystic masses were seen in five epidermoid cysts. Three sacrococcygeal teratomas showed cystic masses with contained calcifications and fattissues, and one cystic teratoma and one tailgut cyst showed well-defined homogeneous cystic masses, and one cavernous hemangioma showed ill-defined soft tissue mass. Soft tissue masses in retrorectal space with destruction of sacral bone were seen in two chordomas, with calcifications, and one giant cell tumor, without calcification. One leiomyosarcoma showed well-defined soft tissue mass with cystic degeneration. Cystic masses with peripheral rim enhancement on enhanced CT scan were seen in two abscesses. One organized hematoma showed round cystic mass with calcifications. Conclusion: CT is very useful in the diagnosis of masses arising in the retrorectal space.

차성숙 대한영상의학회 1989 대한영상의학회지 Vol.25 No.3

Neuroblastoma is one of common malignacy in children and originates from the primitive sympathetic neuroblasts of the embryonic neural crest. Because of the patient have disseminated disease at the time of diagnosis the prognosis will not be good. Nowadays we will have more accurate information for dianosing and staging by applica-tions of modern imaging modalities. the authors analyzed radiological findings of 21 cases of pathologically proven neuroblasto-ma at Inje University pusan paik Hospital. the results were as follows: 1. The mean age was 4 year-old and male to female ration was 11:10 2. The most common clinical finding was palpable abdominal mass(10 cases) and the most common originating site was abdomen(17 cases) the diagnosis could be done in 9 cases by clinical impression, 3. Neuroblastoma was in 19 cases and ganglioneuroblastoma was in 2 cases pathologically. stage I was and the others (20 cases) were more than stage III. 4. Among 19 cases plain film and IVP showed renal abnormality in 16 cases calcification in 6 cases and bone metastases in 10 cases 5, Among 19 cases plain film and IVP showed renal abnormality in 16 cases calcification in 6 cases and bone metastases in 10 cases 5. Among 13 cases ultrasonography showed irregularly marginated heterogenous mass in 12 cases calcification in 8 cases renal abnormality in 9 cases and lymph node metastases in 10 cases 6. Among 12 cases CT finding showed irregular margined soft tissue mass in 11 cases calcification in 9 cases renal abnormality in 9 cases lymph node metastases in 11 cases and bone metastases in 4 cases 7. Among 15 cases bone scintigraphy showed bone metastases in 11 cases and bone metastases in 4 cases. 7. Among 15 cases bone scintigraphy showed bone metastases in 11 cases renal abnormality in 9 cases and primary site uptake in 9 cases

차성숙,전제량 인제대학교 1998 仁濟醫學 Vol.19 No.2

장막하 자궁근종은 외측으로 크게 자라거나 경을 가지고 있는 경우에 난소종양을 포함한 다른 종양과 감별이 어려운 경우가 있다. 최근 3년간 부산백병원에서 복강 및 골반강내 고형성 종괴로 자궁과 인접하고 있었으나 자궁은 정상으로 보여 다른 종양과 감별이 어려웠던 수술로 확진된 장막하 자궁근종 8예의 방사선학적 소견을 분석하였다. 종괴의 크기는 직경이 10∼25cm였으며 외측으로 크게 자란 경우가 4예, 인대내 자궁근종이 2예, 경을 가진 경우가 2예였고, 전 예에서 고형성으로 보였으며 1예를 제외하고는 변성을 보인 부분이 섞여 있었고, 종괴는 1예를 제외하고 자궁과 인접하고 있었으며 자궁은 전 예에서 정상으로 보였다. 6예에서는 난소종양을, 전산화 단층촬영만 시행한 1예는 복강내 간염조직종양을 먼저 생각하였으며, 자기공명영상을 시행한 1예는 자궁근종을 먼저 생각하였으나 난소섬유종과 감별이 어려웠다. 가임기 여성에서 복강 및 골반강내 고형성 종괴가 있을 때 자궁이 정상으로 보여도 장막하 자궁근종을 감별 진단에 포함시켜야 할 것으로 생각된다. Pedunculated or large exophytic subserosal leiomyoma can be confused with other solid mass including ovarian tumor. The radiological findings of eight patients, misdiagnosed as other tumors, were reviewed. The masses ranged in size from 10 to 25cm. The leiomyomas were exophytic in four cases, intraligamentous in two cases, and peduculated in two cases. Masses were solid in all cases, all except one case were degenerated, and all had contact with uteri except one case, but uterine abonrmality was not seen in all cases. Diagnoses of solid ovarian tumor we highly likely in six cases. One mass using CT scan was misdiagnosed as peritoneal mesenchymal tumor, and it was difficult to distinguish leiomyoma from ovarian fibroma in a MR imaging. Although the uterus is normal, subserosal leiomyoma should be included in differential diagnosis of abdominal or pelvic solid masses in women during reproductive years.

요막관 종괴에 대한 초음파 검사 및 전산화단층촬영소견

차성숙 인제대학교 1999 仁濟醫學 Vol.20 No.1

요막관 종괴는 드물게 발생하며 종래의 방사선 검사로는 진단이 어려웠지만 초음파와 CT의 출현으로 진단에 결정적 도움을 주게 되었다. 최근 5년간 부산 백병원에서 경험한 요막관 종괴 8예의 초음파(5예) 및 CT(7예)의 영상소견을 분석하였다. 수술로 확진된 7예는 감염된 요막관 낭종이 4예, 선암종이 2예, 방선상균증이 1예였으며 우연히 발견된 낭종이 1예였다. 요막관 종괴는 초음파 검사 및 CT 소견상 특징적으로 배꼽부터 방광의 천정 부위까지 중심부를 따라 위치하는 종괴를 볼 수 있으며, 1예의 낭종은 방광의 천정 부위 앞쪽에 균일한 낭종으로, 감염된 낭종 4예에서는 초음파 검사상 배꼽부터 방광의 천정 부위까지 이르는 혼합 에코의 종괴로 보였으며, 조영제 주입 후 CT 소견상 저밀도의 종괴가 피막의 조영증강을 보였고, 그 중 2예에서는 방광 천정 부위내로 침범하였다. 방선상균증 1예에서는 고형성 종괴가 방광의 천정 부위를 불규칙하게 침범하였고, 요막관 선암종 2예에에는 모두 점액성 선암으로 CT상 방광 천정 부위에 저음영의 종괴가 조영제 주입 후 주변부 및 고형성 부분에 불규칙하게 조영증강을 보였으며 둘 다 석회화를 동반하였다. 초음파 검사 및 CT는 요막관 종괴의 특징적인 위치와 종괴의 양상을 분석할 수 있으므로 요막관 종괴의 진단에 매우 유용한 검사로 생각된다. Purpose : To evaluate CT and sonographic findings of urachal masses. Materials and Methods: CT images (n=7) and sonogram(n=5) of the surgically confirmed seven urachl masses (four infected cysts, two adenocarcinomas, and one actinomycosis) and an urachal cyst suggested by imaging finding were retrospectively reviewed. Results: Urachal mass had a characteristic location along the midline in continuity with urinary bladder and the umbilicus. Urachal cyst(n=1) was suggested by a homogeneous cystic lesion in anterosuperior to the bladder dome. Infected urachal cysts (n=4) showed as a mixed echogenic mass on the sonogram and a low-density mass with marginal enhancement on the contrast-enhanced CT scan, and involved the bladder dome in two cases. Actinomycosis(n=1) showed a solid class with irregular involvement of the bladder dome. Mucinous adenocarcinoma(n=2) showed as a round low-density mass containing punctate calcifications in anterior wall of the bladder dome with irregular marginal enhancement on the contrastenhanced CT scan. Conclusion : CT and solography are excellent imaging modalities for the diagnosis and evaluation of urachal masses by understanding their typical locations.

차성숙 인제대학교 1988 仁濟醫學 Vol.9 No.1

Iopamidol을 이용하여 1986년 5월부터 1987년 6월까지 본원 방사선과에서 척수조영술을 시행한 133명을 대상으로 조영상 및 부작용을 분석하여 그 결과를 보고하는 바이다. Iopamidol is a new water soluble, non-ionic myelographic contrast media, and is less expensive and has fewer side effects than Metrizamide. The author studied the film quality and side effect in 133 patients with Iopamidol (Iodine 300 mg/ml) myelography in the department of Radiology of Inje Medical College, Pusan Paik Hospltal, from May, 1986 to June 1987. The results were as follows ; 1.The film qualities were good or excellent in 100% of lumbar region, 75% of thoracic region, and 71% of cervical region by using the dye less than 10ml. By using 11-20ml, the film qualities were better in cervical and thoracicregion. 2.The total incidence of side effects was 35.7%, and the most common side effect was headache(22.9%). 3.The cervical legion was the most frequent site of sloe effects(57.1%). 4.The incidences of sloe effects according to dose of contras media were 35% by using less than 10ml, and 40% by using 11-20ml. 5.Except for 1 case of seizure, most of the side effects were mild and disappeared within 48 hous.

영아 간혈관내피종의 영상소견

차성숙,장승국 인제대학교 1999 仁濟醫學 Vol.20 No.1

영아에서 발생하는 간헐관내피종은 자연적으로 크기가 감소되는 양성 종양으로 영상소견과 추적검사가 매우 중요하다. 최근 4년간 부산백병원에서 수술로 확진된 3예와 임상 및 영상소견으로 진단이 가능하였던 1예를 포함한 4예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Infantile hepatic hemangioendothelloma is a benign vascular tumor of the liver in infant. Since spontaneous regression usually starts within several months, imaging findings and follow-up studies are very important. Imaging findings of four cases of infantile hepatic hemangioendothelioma were reviewed, which were surgically proved(3 cases) and diagnosed by the clinical and imaging findings(1 case).

담석환자에서 수술 전 검사로서 자기공명담도조영술

차성숙,최석진 인제대학교 백병원 2002 仁濟醫學 Vol.23 No.5

Purpose : To evaluate the usefulness of magnetic resonance cholangiography(MRC) before biliary surgery in patients with cholelithiasis on ultrasonography. Material and Methods : Seventy four patients with cholelithiasis on ultrasonography underwent MRC before biliary surgery(laparoscopic cholecystectomy:27, cholecystectomy with T-tube drainage:26, cholecystectomy and lobectomy or segmentectomy with T-tube drainage:10, lobectomy or segmentectomy with T-tube drainage:5, lobectomy and cholecystectomy:2, lobectomy or segmentectomy with T-tube drainage:2, T-tube drainage:1, open cholecystectomy:1). For MR imaging, two 1.5T units were used, and single section fast spin echo sequence image, multisection fast spin echo source coronal images(2D or 3D), and maximum intensity projection(MIP) images were obtained. Images were evaluated in detection of stone in GB, intra-hepatic bile duct (IHBD), and extrahepatic bile duct(EHBD) by a consensus of two radiologists. Results : Ultrasonography and MRC showed GB stones in 50(100%) of 5O patients and IHBD stones in 18(100%) of 18 patients. Ultrasonography and MRC showed EHBD stones in 23 (74%) and 30(97%) of 31 patients, respectively. By the detection of EHBD stone on MRC, the surgical methods were changed in 7 patients(16%) of 43 patients in whom ultrasonography showed only GB stones. Stones were detected on MRC in 2 patients in whom ultrasonography showed EHBD dilatation without definite cause. Conclusion : MRC is considered as an excellent imaging modality for detection of stones of GB and bile duct. Therefore we suggest that MRC is a routine study before biliary surgery in patients with cholelithiasis on ultrasonography.
