While most intracranial meningiomas have characteristic CT findings, atypical CT features can give a source of error in the diagnosis of meningioma and the significance of them has scarcely been reported. The authors reviewed records of a consecutive senies of 23 patients with meningioma who underwent operation and pathologically proven from January 1984 to December 1986. Among them 7 cases were analyzed as having atypical CT features of meningioma and CT findings were as follows : focal non-enhancing lucency within tumor(5 cases) focal lucency adjacent to tumor (1 case) and focal hyperdensity (1 cases) and these CT findings were closely correllated with pathological findings.

In an attempt to observe the possible radioprotective actions of single or combined application of reduced glutathione(GSH) and cold exposure in mammals, the albino mouse was subjected to GSH injection, cold exposure at -1$\pm$0.2C and whole-body X-irradiation with 900R either singularly or in combination, or the X-irradiation following the cold exposure and/or GSH injection. The level of protein of the liver, brain and heart was measured at one hour after each application, and the results were compared with the control, i. e., non-irradiated and non-cold exposed normal animal. Protein was measured by the method described by Lowry et al., using Folin-Ciocalteau phenol reagent. The results thus obtained are summarized as follows: 1) The level of protein in the liver, brain and heart of the normal mouse was 101.13, 62.75 and 87.08mg/gm wet wt., respectively. 2) The protein levels of all the organs studied were elevated by the X-irradiation, but decreased protein levels were observe when GSH was given. 3) In the group where the cold exposure was applied, and the X-irradiation was combined with the cold exposure, the protein levels of the organs were similar to the normal value or slightly deceased. 4) When GSH, X-irradiation and cold-exposure were combined, the protein levels of all the organs studied were decreased comparing with the normal.

Sixty-six cases of acute appendicitis were proved by surgery during the period from May 1969 to May 1971. The present study was designated to elucidate the findings of roentgen examination in acute appendicitis. RESULTS : 1. Over 90 % of cases of acute appendicitis showed significant radiographic findings. 2. Distention and fluid level incecum and terminal ileum were disclosed approximately 75% of cases. 3. About 10 % of cases were found extra-alimentary free air. 4. The roentgen finding of the fluid interposed between colonic contents and frank stripesin the right lower quadrant was another interesting finding to suspect acute appendicitis.

박복환,황미수,신명호 영남대학교 의과대학 1999 Yeungnam University Journal of Medicine Vol.16 No.2

Background: Delays in breast cancer diagnosis may occur in young women due to a low index of suspicion. The purpose of this study was to compare mammography and breast sonography in detection of breast cancer and to suggest a reasonable guideline for breast cancer screening examination. Materials and Methods: Among 820 patients, 102 patients were under 35 years and 122 patients were above 60 years of age. We reviewed medical records, mammograms and/or ultrasonography of 49 patients under 35 years and 48 patients above 60 years of ago with pathologically-proven breast cancer. Pathological reports were as follows Invasive ductal carcinoma(IDC) was present 61.2% of patients in the young age group and ductal carcinoma in situ(DCIS) in 16.3%. IDC was present in 66.6% of the patients in the old age group, and DCIS in 8.33%. We analyzed mammography and ultrasonography to evaluate their usefulness in detecting breast cancer in patients under 35 years and over 60 years of age. Results: The mammographic results are as follows : 1) detection rate of lesion: 83.8%(under 35yrs), 100%(over 60yrs) 2) sensitivity of cancer: 67.6%(under 35yrs). 91.2%(over 60yrs) The ultrasonographic results are as follows : 1) detection rate of lesion: 100% 2) sensitivity of cancer: 87.2%(under 3syrs), 96.7%(over 60yrs) The breast cancer detection rate in women under 35 years old was comparable to that of women above 60 years old in our study. Conclusion: A striking histologic finding in the two groups was a higher incidence of nuclear Grade Ⅱ and Ⅲ tumors. This finding correlates with the reported increased incidence of high grade tumors in young women and may correlate with the poorer prognosis of breast cancer in young patients. We conclude that early screening examination is helpful for early detection of breast cancer in women under age 35.

자궁 종괴의 자기공명영상

박복환 영남대학교 의과대학 1995 Yeungnam University Journal of Medicine Vol.12 No.2

결론적으로 MRI는 종괴의 성상과 특성을 잘 나타내 주므로 감별진단이 보다 용이하고, 자궁경부암이나 자궁내막암 같은 악성종양의 경우에서의 진단은 물론 병기를 정확하게 밝혀줌으로써 치료방침을 결정하고 예후를 판정하는데 매우 유용하다. 아울러 MRI의 가장 큰 단점으로 꼽히고 있는 시간과 비용의 절감을 위해서 빠른 속도로 기술과 장비가 개선되고 있고, 촬영기법에서도 여러 가지 coil과 고속영상기법 및 역동적 조영증강방식 등의 개발을 통해 더욱 고화질의 영상을 얻을 수 있을 것으로 기대된다.

선천성 중장 회전 이상의 방사선학적 소견

고중곤,황미수,안재홍,박복환 영남대학교 의과대학 1997 Yeungnam University Journal of Medicine Vol.14 No.2

1987년 5월에서 1997년 10월까지의 영남대학교 의과대학 부속병원에서 임상적으로 선천성 중장 회전 이상을 의심하여 방사선학적으로 진단되고 수술을 시행한 17명의 환아를 대상으로 임상소견과 수술 기록 및 방사선학적 소견을 후향적으로 분석한 결과는 임상적인 주된 증상은 구토나 구토를 동반한 복통이었으며, 수술 소견상 16명의 환아에서 선천성 중장 회전 이상이 확진되었고, 1명의 환아에서 중장 회전 이상 없이 윤상 췌장으로 진단되었다. 모든 환아에서 상부 위장관 조영술과 바롬 관장술을 시행한 결과, type I인 경우가 3명, type IIA가 2명, type IIC가 1명, type IIIA가 5명, type IIIc가 4명이었으며 이중에서 type IA로 진단된 1명은 수술 소견상 윤상 췌장으로 확인되었다. 수술로 확진된 16명의 환아중 13명은 상부 위장관조영 소견에서 선천성 중장 회전 이상이 진단되었고 3명의 환아에서는 상부 위장관 조영 소견은 확실하지 않았으나 바륨 관장·소견상 선천성 중장회전 이상이 증명되었다. 결론적으로 선천성 중장 회전 이상은 중장 염전과 장 괴사와 같은 치명적인 합병증으로 출생 첫 주에 높은 사망률을 보이기 때문에 조기 진단이 매우 중요하며, 임상적으로 선천성 중장 회전 이상이 의심되면 상부 위장관 조영술을 먼저 실시해야 하고 십이지장 공장 접합부가 정상적으로 위장 유문부와 같은 축상에 있는지 우측 측사위 촬영에서 확인해야된다. 비록 정상 소견을 보일지라도 위음성이 있을 수 있으므로 반드시 바륨 관장술을 실시해서 압박, 사위, 좌측와위 촬영에서 맹장과 회장 말단부의 위치를 확인해야 될 것으로 생각된다. An accurate early diagnosis of congenital midgut malrotation is essential to prevention of catastrophic effects of volvulus. To evaluate the usefulness of radiologic examinations in diagnosing intestinal malrotation, we retrospectively analyzed radiologic findings and operation recored of 17 intestinal malrotation patients, who were rediologically diagnosed. The age range of the patients studied were from 1day to 12years. The presenting symptoms were vomiting, vomiting with abdomnal pain, abdominal distention, diarrhea and failure to thrive. The viewpoints of this analysis were the location of duodeno-jejunal flexure on barium meal and cecal location on barium enema. Sixteen of 17 patients, who were radiologically diagnosed, were surgically proven, but one patient with annular pancreas was false positive. In the case of 3 surgically porved patients, malrotation was suspected on barium meal prior to the barium enema, but final diagnosis was determined on barium enema examination. We concluded that a barium enema should be performed on all children with suspected malrotation where the initial upper gastro-intestinal study was normal or suspicious on account of the small incidence of false positive and false negative barium meals.

정호선,이상진,손미영,권혁포,황미수,김선용,장재천,박복환 영남대학교 의과대학 1989 Yeungnam University Journal of Medicine Vol.6 No.2

30례의 종격동 종양의 CT분석 결과, 저자들은 다음과 같이 요약 할 수 있었다. 1. 가장 흔한 종양은 흉선질환 이었으며, 그 다음으로는 기형종, 림프종, 기관지성 낭종, 신경종, 심막낭종의 순이었다. 2. 5례의 흉선종은 균일한 충실성 음영의 종괴로 보였으며, 석회침착, 소엽형성이 각각 1례에서 보였다. 악성흉선종 중 1례에서 피낭형성이 잘된 낭성 종괴로 보였으며, 흉선암종은 주위 경계의 소엽형성을 보인 균일한 음영의 종괴로 보였다. 3. 전 례의 기형종은 모두 낭성종괴로 보였으며, 지방과 석회음영은 각각 2례, 4례에서 보여졌다. 4. 신경종은 4례 모두에서 후종격동에 위치한 균일한 음영의 종괴로 보여졌다. 5. 기관지성 낭종은 기관분기부 하방, 부흉곽지역에 각각 1례, 후기관부에 2례 있었으며, 모두 균일한 음영의 낭성 종괴로 보여졌다. 6. 심막낭종은 심장 주위 경계를 따라 난형모양의 낭성 종괴로 보여졌다. 결론적으로 종격동 종괴의 진단에 CT를 실시 함으로써 종괴의 정확한 위치, 크기및 특징적인 구성성분을 관찰할 수 있으며, 이러한 소견으로 종괴의 감별진단에 도움을 얻을 수 있다. Computerized Tomography is now well established and important noninvasive method of diagnosting mediastinal mass lesions because of its superior imaging of their size, location and internal composition. Authors analysed and present CT findings of 30 surgically proven mediastinal tumors and cysts that were studied and treated at the Yeungnam University Hospital during recent years. The most common tumor was thymona(9cases), and teratoma(6 cases), lymphoma(6 cases), bronchogenic cyst(4 cases), neurogenic tumor(4 cases), pericardial cyst(1 case) were next in order of frequency. There were 5 cases of thymoma showing homegenous solid density mass, 2 cases were malignant thymoma and myasthenia gravis was present in 2 cases, A case of thymolipoma and a case of thymic carcinoma were included. All teratomas were cystic masses but pathognomic fat, and calcified density were seen only in 4 cases, 5 cases were located in anterior mediastinum and 1 case was in posterior mediastinum. Lymphoma(3 Hodgkin's and 3 non-Hodgkin's) appeared as irregular lobulated mass in anterior mediastinum. Neurogenic tumor(2 ganglioneuroma and 2 neurilemmoma) appeared as homogenous density mass located in posterior mediastinum. Among the 4 bronchogenic cysts, 2 were located in retrotracheal area, I was located in subcarinal and I was in parathoracic area. One case of pericardial cyst was oval shaped cystic mass located in left pericardiac border.
