Pulmonary Aspergillosis의 방사선학적 고찰

권귀향 대한영상의학회 1977 대한영상의학회지 Vol.13 No.1

Pulmonary aspergillosis can be hardly recognized as such roentgenologically; the smooth dense lesions, often with cavities, are indistinguishable from Tuberculosis and other disease. Since tuberculosis is a common pulmonary disease in this country. Aspergillosis is easily misdiagnosed as tuberculosis and a acute form of aspergillosis is misinterpretated as pneumonia, because of their similartities in roentgenographic findings. Dense spherical masses of fungus growth, called mycetomas or Aspergillomas and better known as fungus balls, are sometimes found in association with destructive pulmonary disease, including carcinomar and bronchiectasis. Such a mass can be confused with tumor but may be indentified if it is lying in a cavity and mantle of air is seen between the mass and the cavity wall. Tomograms will sometimes show a characteristic air cap. In sputum culture there lies a troublesome problem because of a ubiquity of Aspergillus. And there is no reliable skin test or ser logic test Aspergillosis. The 18 cases of Aspergillosis, proven by surgery, histopathology or/with sputum culture under a strict procedure, were encountered at National Medical Center in the long period of time from April 1962 to November 1976, and those cases are analyzed radiologically and clinically. The following results were obtained: 1. The 10 cases of pulmonary aspergillosis were found in male and the 8 cases in female. Their age range was wide from 20 to 60 years. And the 12 cases (67%) were in the age of 20 to 40 years. 2. The most frequent site of the lesion was in the right upper lobe (9cases). 3. There were 12 (67%) cases of primary aspergillosis and 6 cases of 2ndary one. 4. The characteristic fungus ball with the air cap within the cavity was demonstrated in 8 cases n the tomographic study. 5. The main clinical symptoms were composed of chronic coughing, purulent sputum and hemoptysis and the 10 cases of these patients were misdiagnosed to have tuberculosis. And the 5 c ses had antituberculosis therapy for more than 5 years. 6. The pulmonary tuberculosis and pleurisy were the most frequent associated disease in pulmonary Aspergilosis.

56세 남자가 약 1개월간 지속된 기침 및 객담을 주소로 내원하였다. 본 환자는 약 10년 전 류마티스관절염 (rheumatoid arthritis)를 진단 받은 후 약물 치료를 시행하고 있었으며, 약 3개월 전 흉추의 압박 골절로 인하여 외부 병원에서 척추성형술 (vertebroplasty)을 시행한 과거력이 있었다. 입원 후 시행한 단순 흉부 소견 및 흉부 전산화 단층 촬영 상 acrylic bone cement에 의한 작은 폐 혈관들의 색전증 (embolism)이 확인되었다. 척추성형술 후 드물게 발생하는 cement 색전증은 시술 중 acrylic bone cement의 perivertebral migration을 인지하지 못함으로써 발생 할 수 있다. 이러한 합병증의 발생은 척추성형술의 적절한 시술 방법에 대한 인식 및 시술 중 투시 (fluoroscopy) 또는 전산화 단층 촬영 (computed tomography, CT)을 이용한 imaging guidence를 통하여 감소될 수 있을 것으로 보인다.

There cases of mass disaster, KAL accident in Tripoli, express bus accident and park cemetry accident in Korea, were referred to the National Institute of Scientific Investigation, Seoul, Korea for individual identification (ID). All the cases were thoroughly investigated to establish the most scientifically sound ID possible. In addition to evidence from fingerprint, dental, anthropological, visual, pathological, blood typing and superimpose according to the case, X-ray studies were attempted. In KAL case, 52 of 59 were identified by comparison radiography. Differential diagnosis was accomplished in 2 misidentified bodies in express bus case by radiography. Radiologic examination also revealed good characteristics in park cemetry case, however, did not satisfactorily contribute to ID because of restricted information.

The study was undertaken to asses the changes in the size and densities of intracranial hematomas by analyzing the sequential C.T. examination of 23 patients at Soon Chun Hyang College Hospital from Jul. 80 to Aug. 81. The results were as follows: 1. The high densities of hematoma were reduced slowly in size and density. 2. The factors influence the rate of changes were the cause of hematoma, hematoma location, age and sex of patient, and initial hematoma size. 3. The C.T. findings that indicate complete absorption of hematomas were normalization of mass effect, not disappearence of hematoma densities. 4. In intracerebral hematoma, the high density of hematoma reduced it's density and mass effect about 4-6 weeks duration. 5. In subdural hematoma, about 7 weeks after head trauma, the C.T. findings were normalized.

"Cerebrovascular Moya Moya" Disease의 방사선학적 고찰과 임상 소견

권귀향,김기정 순천향의과대학 1979 Journal of Soonchunhyang Medical Science Vol.2 No.4

In 1963, Susuki ect described in jultiple progressive intracranial arterial occlusion and named “Moya Moya” disease. Many cases of Moya Moya disease had been reported and discussed by some Japanese authors and they asserted that Moya Moya disease is characterized by the intracranial congenital or developmental anomaly apparently confined to Jqapanese. But more recently, this disease have been reported by some non-Japanese authors, in the United States, Europe and Korea. We have experienced 6 cases of cerebrovascular Moya Moya disease from August 1976 to March 1979. We were proved by carotid and vertebral angiogram and clinical assessment. The results are as follow: 1. Age distribution was ranged from 7 to 41. Age under 20 were 4 cases and 4 cases were males and 2 females. 2. There were no contributory factors to cerebrovascular Moya Moya disease with regard to familial back ground. 3. Clinical manifestations were mainly headache, vomiting, convulsion, hemiparesis and visual disturbance. 4. Angiographic findings reveal occlusion or stenosis of internal carotid artery at the supraclinoid portion in all cases except for one (petrosal region) and also abnormal fine vascular netword, poor or non-visualization of anterior and middle cerebral artery but relatively normal opacification of posterior cerebral artery. 5. Among these 6 cases, there were no evidence of subarachnoid hemorrhage or aneurysm on cerebral angiography.

Human clonorchiasis is one of the most common trematode disease and of very important public health problem in Korea. A number of serological techniques have been in use for diagnosing parasitic diseases, efforts in recent years have been made for the development of a more new promising serological technique. The present study was conducted to evaluate to evaluate the diagnostic potentialities of human clonorchiasis by the indirect fluorescent antibody test (IFAT) using frozen sectioned antigen of adult worm of Clonorchis sinensis. A total of 117 sera from clonorchiasis patients, 16 sera from persons with other parasitic infections and 9 sera from non-infected healthy persons were tested. Frozen sections of adult worm of C. sinensis were placed on the spot-slide and incubated in two fold serially diluted sera and subsequently stained with goat anti-human immunoglobulin labeled with fluorescein isothiocyanate and Evans blue. The worm sections were examined with a fluorescent microscope, A.P\O. Series No. 10 Microstar. If the test is negative, the preparations are colored a uniform red. On ? other hand, if the test is positive, the adult worm sections display an intense green fluorescence localized in the tegumental region of C. sinensis. The results obtained are as follows: 1. The results indicated that IFA titers at 1/16 were regarded as positive reaction. Therefore, the positive reaction revealed in 72 (61.5%) out of 117 sera from clonorchiasis patients. 2. In the intensity of Clonorchis infection, the positive reactions of IFA titers showed 28.1% in light infection, 68.9% in moderate infection, 77.8% and 84.6% in heavy and very heavy infection respectively. 3. All serum samples from 16 cases infected with parasites other than Clonorchis were diagnosed as negative. Only one out of 9 sera from non-infected healthy cases showed false positive. With the above results, IFAT has great practical advantage since the antigen is easy to place on slides and easier reading than those of adult C. sinensis particles as an antigen. Therefore, this study suggest tat the IFAT can be applied in the diagnosis of human clonorchiasis.

High resolution ultrasonographic exaimnation of orbit is very safe, specific and reliable way to obtain image of eyeball, especially in presence of pathologic conditions of anterior segment. Such conditions make fundus examination almost impossible. 22 eyeballs of 18 cases ultrasonsgrams, which were referred under the impression of cataract were analysed, though cataract is easily recognized by physician on inspection. The results were as follows : 1. Ultrasonographic findings of cataract are a) Thickening of lens:11 cases among 13 cases (85%) b) Demonstration of lens echo in whole circumference:20 cases among 22 cases (91%) c) Multiple internal lens echo:10 cases among 22 cases (45%) 2. Associated diseases are retinal detachment 5 cases, vitreous hemorrhage 5 cases, vitreous membrane 4 cases, foreigh body 3 cases and lens dislocation 1 case. 3. Patterns of cataract are after cataract 1 cases, congenital cataract 1 case, complicated cataract 3 cases, diabetic cataract 3 cases, senile cataract 6 cases, traumatic cataract 6 cases, and cataract in Mongolism 2 cases.

In arteriovenous malformation, cerebral angiography is the last and conclusive method of diagnosis, although CT has been helpful for determination of the location and extension of the lesion. We reviewed cerebral angiography combined with CT of 30 cases of AVM who were suspected clinically during the period from Jan. 1979 to Dec. 1983 in SCH hospital. The results were as follows: 1. The sex distribution of cases was 17 males and 13 females (1.3:1) and 60% of cases were between second and forth decade. 2. In CSF finding, subarachnoid hemorrhage were noted in 9 cases. (6%) 3. Only 1 case showed calcification in simple skull series and the others were normal. 4. The locations were parietal area(46%), frontal area(21%), temporal area(11%) and left side was more common than the right side. (62%) 5. The feeding arteries were MCA(32%), ACA(32%), PCA(7%) and the draining veins were superior cortical vein(32%), inferior sagittal sinus(12%), vein of Galen(12%) and internal cerebral vein(12%). Multiple feeding arteries were noted in one case. 6. The size between 1∼2cm was 12 cases(41%), below 1cm was 7 cases(20%), between 3~4cm was 5 cases(16%), and above 4cm was 3 cases (13%). 7. CT was done in 26 cases, Among these, 4 cases(15%) showed serpingineous mixed density with marked enhancement and remainders showed intracerebral, intraventricular and subarachnoid hemorrhage, ischemic change, mass effect and hydrocephalus. 8. Conservative therapy was done in 12 cases, total removal of anomalous vessels in 14 cases, clipping in 2 cases and radiation therapy in one case.

Cleidocranial dysostosis is rare congenital syndrome which was originally described by Marie and Sainton in 1897. According to the classic discription, the syndrome consist in 1) Various degree of hypoplastic change of the clavicles 2) Delayed ossification of the cranial sutures and incresed width of the skull 3) Defects in the teeth, and 4) Hereditary characteristics. And these authors used the term Cleidocranial Dysostosis. But Rhinehart called attention to the mutational character of the disease and accordingly recommended that its name be changed to Mutational Dysostosis. Subsequent to the discovery of cleidocranial dysostosis, new anomalies extending practically throughout the entire osseous system have been described. We experienced a new case of Cleidocranial Dysostosis patient with absence of distal portion of both clavicles, unusual scapular and defect of ossification on the skull. Also this patient has high type of obstruction of imperforated anus. And we present this case based on clinical and radiological findings with review of some literatures.
