Among the skeletal tuberculous spondylitis is high incidence and curable disease, if early diagnosis and treatment are possible. We reviewed clinical manifestations and radiologic analysis of 30 cases tuberculous spondylitis from May 1983 to Sept. 1986, at Yeungnam medical center, Yeungnam University. The results were follows: 1. The frequent involve sites were thoracolumbar vertebra. 2. The continuous lesion is 86.7% of the all cases. 3. The most common type was intervertebral type, and lytic and sclerotic lesion were same incidence. 4. Paravertebral abscess, kyphosis and disc space narrowing were demonstrated more than 80.0% of the cases. 5. Computed tomography was more accurate diagnostic method rather than conventional plain study to evaluation of extent of lesion, involvement of spinal canal and cord, and size and location of paravertebral abscess. And CT guided abscess drainage procedure was helpful to diagnosis and treatment. 6. Ultrasonography was helpful to differential diagnosis between paravertebral abscess and other solid mass, and useful to follow up study of paravertebral abscess after treatment.

Acute cavitating pulmonary infection with a mycetoma is sometimes occur in immunocompromised patient. Most mycetoma lesions are due to Aspergillus species, and lesion caused by Candida species is rare. So we report an experienced case that pulmonary and rib infection caused by Candida species-'in -AML patient and complete remission with previous reports.

Magnetic resonance (MR) is rapidly emerging technique that provides high quality images and potentially provides much more diagnostic information than do conventional imaging modalities. MRI is conceptually quite different from currently used imaging methods. The complex nature of MRI allows a great deal of flexibility in image production and available information, and key points are as follows. 1. MR offers a non-invasive technique with which to generate in vivo human images without ionizing radiation and with no known adverse biological effects. 2. Imaging mechanism of MRI is quite different from conventional imaging modality and for more accurate diagnostic application, It is necessary for physician to understand imaging mechanism of MRI 3. M.R. makes available basic chemical parameters that may provide to be useful for diagnostic medical imaging and more specific pathophysiologic information which are not available by alternate techniques. 4. M.R. can be produced by number of different methods. This flexibility allows the imaging technique to be applicated for particular clinical purpose. Multiplanar and three dimensional imaging may extend the imaging process beyond the single section available with current CT. 5. Future directions include efforts to; a. Further development of hard ware b. More fastening scan time c. Respiratory and cardiac gated imaging d. Imaging of additional nuclei except hydrogen. e. Further development of contrast media f. MR in vivo spectroscopy g. Real time MR imaging

Takayasu's arteritis is an arteritis of undetermined etiology, which affects the aorta, proximal portion of its major branches, and causes narrowing, occlusion, or aneurismal dilatation of vessel. Authors report 2 cases of Takayasu's arteritis with brief review of the literature.

A case of foregut cyst communicated with esophagus and lined by bronchial mucosa is reviewed and its embryologic base of maldevelopment it discussed. It is not always easy to distinguish between digestive and respiratory cyst in mediastinum. There is whole range of intermediate between a cyst with ciliated and one with squamous or columnar mucosa. Origin of this dysembryoplasia is difficult to determine when on consider that the esophagus is covered with ciliated epithelium until the eleventh week of fetal life and that ciliated growth are found on its wall until the sixth month of the fetal life. And we concluded, general agreement is that cysts which have gastric epithelium in whole or in part, represent a distinct type and should be classified as (gastro) enteric cyst, mediastinal cyst containing cartilage were considered definitely as respiratory (bronchial or bronchogenic) cyst.

Authors retrospectively analyzed ultrasonographic findings of 12 cases of breast carcinomas which were proven pathologically at Yeungnam University Hospital from March 1992 to August 1992. Classically, breast carcinomas were described as irregular and lobulated hypoechoic solid masses with inhomogeneous internal echoes and frequent attenuation of the sound beam. And other additional ultrasonographic findings were echogenic rim, disruptions of superficial layer, microcalcification, skin thickening and so on. In our studies, not all of these findings of breast carcinomas were found in each case, but most of these findings were noted. However, several studies have demonstrated considerable overlap in the ultrasonographic appearance of benign lesions and carcinoma. Thus, accurate sonographic determination of the type of solid mass is not possible with current ultrasonographic imaging techniques and criteria. For more accurate diagnosis of breast lesions, sonographic and other imaging techniques are interpreted together.

PURPOSE: To evaluate intrahepatic nodular lesions detected on CTAP but not on conventional contrast CT in regard to its relationship with satellite nodules or borderline malignancies. MATERIALS AND METHODS: From June 1991 to March 1994, CTAP was undertaken in 132 cases with confirmed hepatocellular carcinoma(HCC), of which 35 cases having 82 lesions were suitable for analysis(excluding the cases which had no follow-up studies, showed segmental abnormal portal perfusion, no additional lesions and, or inumerable lesions). The CTAP findings were compared with those on artery dominant imaging studies (angiography, DSA, bolus dynamic CT, arterial CT, Lipiodol CT) taken during the same period(to confirm the presence of lesions) and the findings on follow-up imaging studies(to assess the developemerit of malignancy). RESULTS: Arterial vascularity was identified in 35 of 82 lesions(42.7%) on arterial dominant imaging studies. Developement into malignancy was identified on follow-up imaging studies in 25 of remained 47 lesions(53.2%). CONCLUSION: The total positive predictive value of nodules on CTAP was 73.2%(35+25/82), but the predictive value for HCC by follow-up only was 53.2%. Given'the difficulties in detecting intranodular arterial flow and the short follow-up duration in many patients, the actual positive value might be higher.

With simple abdomen, double contrast colon study, and ultrasongraphy, authors retrospectively analyzedradilogic findings of 46 cases which were proved periappendiceal abscess, due to perforation of appendix, byhistology or follow-up ultrasnongraphy from May in 1983 to July in 1985 at Yeung-Nam University Hospital. Theresuls obtained were as follows: 1. Of 46 cases, 24 cases were males and 22 cases females, with the results ofabove statistics, periappendiceal abscess was not influenced by sex. 2. Periappendiceal abscess was mostfrequently demonstrated in forties. 3. Comparison of ultrasonography and B.E. Pseudorenal pattern(Ultrasonography)- well defined defect (B.E.) Cystic pattern(Ultrasonography)- serrated defect (B.E.) 4. Missed 2 cases inultrasonography were detected in B.E., i.e. sensitivity of B.E. is higher than that of ultrasonography. 5.Differences of ultrasonography and B.E.
