PURPOSE: The purpose of this study was to compare mammography and breast sonography in detection of breast cancer and to suggest reasonable guideline of breast imaging in breast cancer patients under 30 years of age in whom breast cancer shows different clinicopathologic characteristics compared with breast cancer in older women. MATERIALS AND METHODS: A. uthors reviewed medical records of 27 patients under 30 years of age with pathologically-proven breast cancer. Age, family history, physical examination findings, indications for breast s0nography were reviewed. Cases in whom breast cancer lesion is detectable and cases in whom not detectable using mammography or breast sonography were reviewed. And then, authors evaluated the usefulness of each method and reasons for nonvisualization of lesion on mammography. RESULTS: Among 27 patients, 25 patients had palpable breast mass as indication of mammography and breast sonography. Cancer lesions were detectable in 16 of 25 patients (64%) on mammography and 24 of 25 patients (96%) on breast ultrasonography. Reasons for nonvisualization of cancer lesions on mammography were dense breast with nodular parenchyma pattern and minimal breast change of ductal carcinoma in situ. CONCLUSION: In breast cancer patients under 30 years of age who have palpable breast mass as a initiaJ, and main clinical problem, breast ultrasonography is superior to mammography in detecting and diagnosing breast cancer. We suggest that guidelines can avoid unnecessary mammography in these patients.

PURPOSE: The objective of augmentation mammoplasty includes reconstruction and cosmesis after breast surgery Increasing frequency of the procedure has been related with increased complications. Authors evaluated the value of breast MRI in the diagnosis of complications after augmentation mammoplasty. MATERIALS AND METHODS: Authors studied 42 breasts of 24 patients, who had undertaken augmentation mammoplasty. We evaluated findings of mammography, ultrasonography, and breast MRI in all patients. We used variable MRI sequences for better evaluation of implant status. The results were compared with the findings in surgical field. RESULTS: In all imaging studies, nodule or mass was indentifiable in the cases of interstitial paraffine injection(8 breasts), interstitial silicon injection(7 breasts), and herb medication(2 breasts). However, the differentitation between malignant and benign nodule was only possible at dynamic breast MRI. Mammogram was not helpful in the evaluation of extracapsular rupture in the cases of silastic bag insertion. In sonogram, identification of echogenic material was possible, although, false negative and false positive rate were high. MRI was able to visualize contour of entire implant and it was able to easily recognize low signal internal structure. CONCLUSION: MRI was the most accurate diagnostic tool in the evaluation of the character of the palpable mass after augmentation mammoplasty and early detection of breast implant rupture.

Open discectomy is one of usual treatment for herniated intervertebral disc. We may expect the reduction of height of intervertebral disc due to decreased volume by partial resection of herniated disc. But the effect of decreased height of intervertebral disc space to posterior joint and spinal canal has not been identified, and the correlation between the amount of reduced height and the changes of range of motion has been undetermined. Thus, we analyzed radiologic changes of disc height and segmental motion by the flexion-extension view in 20 patients who had undergone discetomy for prolapsed intervertebral disc from June 1989 to January 1991 who could be followed up for 3 years or more. As a result, lumbar discetomy associates with 1) significant decrement of disc height (average 14%), 2) decreased disc motion of involved segment without hypermobility (average 34%), 3) hypermobility of adjacent segment, 4) and posterior facet overriding consistent with recurred low back pain.

BACKGROUND: Fine Needle Aspiration Cytology (FNAC) is widely accepted as the most accurate procedure to differentiate malignant from benign thyroid nodules. It is a simple, safe, and inexpensive procedure, and the accuracy of FNAC is relatively high; however, its success usually depends upon the skill in using the aspiration technique and the experience and skill of the cytologist. The authors confirmed the diagnostic value of preoperative FNAC in differential diagnosis of thyroid nodules treated by the surgical resection. METHODS: Three hundred fifty specimens were taken in the Department of Surgery, Inje University College of Medicine, from July 1990 to June 1996. Fifty-one males and 299 females with ages ranging from 11 to 73 years were enrolled. The cytology of FNAC was compared to the final histologic diagnosis. RESULTS: The number of inadequate smears (or sampling error) was 15.7%. Preoperative cytologic diagnoses was consisted of 198 cases of benign disease (92 cases of nodular goiters, 96 cases of follicular lesion types III, and 10 cases of thyroiditis), 12 cases of highly suspicious malignant lesions (follicular lesions type II), and 85 cases of malignant disease (71 cases of papillary carcinomas and 14 cases of follicular lesions type I). Histologic diagnoses consisted of nodular goiters in 116 cases, adenomas in 66 cases, thyroiditis in 9 cases, papillary carcinomas in 84 cases, and follicular carcinomas in 20 cases. These results has an 84.6% sensitivity, a 95.2% specificity, a 15.3% false negative rate, and a 4.7% false positive rate. In the fifty-five cases of inadequate sampling, 13 cases (23.6%) were malignant lesions histologically. In the 16 cases proven as false negative, nine cases were papillary carcinomas, and 7 cases were follicular carcinomas histologically. Thirteen cases (16.1% of 27 cases of cystic lesions) of cystic nodules revealed malignant neoplasms histologically. CONCLUSION: FNAC is a single, useful diagnostic procedure for the initial screening for malignancy in thyroid nodules. Performing repeated aspiration in cystic nodules and clinically suspicious cases could reduce inadeguate sampling and the false negative rate.
