PURPOSE: The aim of this study was to determine the potential usefulness of uterine artery embolization (UAE) for the management of uterine leiomyoma. MATERIALS AND METHODS: Sixty nine patients (mean age; 40.3 years, age range; 31-52 years) who underwent UAE for symptomatic fibroids (with menorrhagia, dysmenorrhea and bulk-related symptoms) from January 2000 to December 2000 were retrospectively analyzed. The mean follow-up period was 3.5 months (range: 1-8 months). The fibroids ranged in size from 2.0 cm to 13.2 cm with a mean size of 5.8 cm. We performed embolization using polyvinyl alcohol particles (250-710microgram). The improvement of the clinical symptoms was analyzed. Reduction of the uterine and predominant fibroid volumes was assessed using MRI. RESULTS: Symptom improvement for the menorrhagia (87.5%), dysmenorrhea (83.3%) and the bulk-related symptoms (79.2%) was reported. Complications included ovarian failure in four patients (5.8% of the total patients, mean age: 43.3 yrs) and infection in three patients (4.3% of the total patients) who underwent conservative management with intravenous antibiotics and analgesics. The volume reduction rate of the uterus and the predominant fibroids after uterine artery embolization were 36.3% and 56.6%, respectively. CONCLUSION: UAE is a promising new treatment for symptomatic fibroids and may be a valuable alternative to hysterectomy.

Cutaneous metastasis from breast cancer can occur by direct invasion, lymphatic and vascular spread as well as iatrogenic implantation. Metastasis that occurs by iatrogenic implantation after needle biopsy is very rare but the potential risk must be considered. In this report, we describe a case of breast cancer cutaneous metastasis that occurred by iatrogenic implantation following core needle biopsy. A 53-year-old woman presented with a 1x1 cm sized erythematous nodule at the biopsy site after breast conserving surgery for primary cancer. Histopathological findings confirmed cutaneous metastasis. The possibility of this consequence must be considered when performing needle biopsies.

A 75-year-old female visited our hospital with bilateral adrenal masses that were detected incidentally during lumbar spine magnetic resonance imaging (MRI) for the evaluation of radiating flank pain. Consecutive computed tomography and MRI revealed bilateral adrenal masses with no evidence of lymph node enlargement or local invasion; 2[(18)F]fluoro-2-deoxyglucose (FDG)-positron emission tomography showed an intense FDG accumulation in both adrenal glands without abnormal FDG uptake in extra-adrenal regions. The laboratory test results were within normal ranges. We performed a bilateral adrenalectomy. The pathologic diagnosis of both adrenal masses was consistent with adrenocortical carcinoma. The patient recovered well with no complications.

PURPOSE: To identify MR predictors of bone cement leakage in patients receiving percutaneous vertebroplasty. MATERIALS AND METHODS: Percutaneous vertebroplasties were performed in 45 vertebras (T7; one, T8; two, T10; two, T11; two, T12; eight, L1; fifteen, L2; eight, L3; five, L4; two) in 35 patients (age 52-83). The procedure was performed using an 11 G Jamshidi needle, which was inserted into the target by the bipedicular approach. Kyphoplasty, unilateral pedicular approach and extrapedicular approach cases were excluded. Shortly after the procedure, all patients underwent a noncontrast CT covering the vertebroplasty sites. A retrospective study was performed to determine whether cement leakage is related to any of following MR findings: presence of cortical disruption of the vertebral body, severity of body compression (proportion of abnormal to normal vertebral body volumes), bone cement amount, bone cement amount/severity of body compression ratio, proportion of low-signal area in a vertebral body on T1 weighted image, presence of either vacuum or cystic portion below a linear dark signal in a fractured vertebra, and the location of dark signal intensity line in a vertebral body. Logistic discrimination model stepwise method was used in the statistical analysis. RESULTS: On post-vertebroplasty CT scan, bone cement leakage was detected in or around 29 vertebrae (64%), including 11 vertebrae (24%) where leakage was found in the epidural space or radial vein. No patients displayed any neurological symptoms or signs. The most frequent site of bone cement leakage was the anterior external vertebral venous plexus (49%). Endplate cortical bone disruption was related to an increased risk of intervertebral bone cement leakage (p<0.05). Bone cement leakage tended to occur less frequently when there is a vacuum or cystic change below the dark linear signal intensity in a fractured vertebra (p<0.05). No other MR findings showed a statistically significant correlation with bone cement leakage. CONCLUSION: On pre-vertebroplasty MR imaging, vertebral endplate cortical bone disruption and vacuum or cystic change below dark linear signal intensity in fractured vertebra showed a significant correlation with bone cement leakage.

PURPOSE: To assess the usefulness of the Hounsfield number, measured by a non-contrast enhanced pelvic CT, after a uterine artery embolization as an index of the successful outcome of a uterine fibroid embolization (UFE). MATERIALS AND METHODS: The study subjects included 15 women (age range: 28-49 years, mean age: 36.4 years) diagnosed with symptomatic uterine myomas and seen from March 2003 to August 2005. A non-contrast enhanced pelvic CT scan was performed six hours after a uterine artery embolization. The global and maximal CT numbers were measured for each myoma. In addition, a pelvic MRI was performed to measure the volume of each myoma prior to and 6 months after the UFE. The relationship between fibroid volume reduction and the global CT number were prospectively analysed. RESULTS: The mean global CT number was 91.25 HU in Group I and 40.8 HU in Group II. Further, the mean fibroid volume reduction rate was 73% in Group I and 10% in Group II (p < 0.05). CONCLUSION: The global CT number measured by a non-contrast enhanced pelvic CT is a useful predictive factor of a successful uterine fibroid embolization.

PURPOSE: To establish the relationship between serum prostate specific antigen (PSA) concentration and age in a community-based population without clinically evident prostate cancer, a population based screening study was performed in a rural area in Southern Korea. MATERIALS AND METHODS: From January 1999 to December 1999, 1,278 volunteer men aged from 40 to 89 years in Namhae, Korea participated in a clinical examination that included a serum PSA determination (TANDEM-R assay), digital rectal examination and transrectal ultrasonography. The subjects who had clinical evidence of prostate cancer and high PSA concentration (>10ng/ml) were excluded. The PSA levels were compared with age using Pearson correlation and linear regression analysis. RESULTS: The serum PSA concentration correlated with patient age (r=0.129, p=0.001). The observed 95th percentile increased from 1.37ng/ml for subjects in the 40's to 6.18ng/ml for subjects in the 80'2. The reference range for serum PSA (95 percentile) for men in the 40's was 0.24 to 1.37ng/ml; for 50 to 59 years, 0.27 to 2.68ng/ml; for 60 to 69 years, 0.25 to 4.00ng/ml; for 70 to 79 years, 0.29 to 4.55ng/ml; and for 80 to 89 years, 0.31 to 6.18ng/ml. CONCLUSIONS: Our data showed that the serum PSA concentration directly correlated with patient age (Pearson correlation coefficient=0.129, P=0.001). Thus, rather than relying on a single reference range regardless of different age groups, it may be more appropriate to have age-specific reference ranges. Our data were lower than that of the Western data, and could provide an adjunctive information in interpreting PSA data in Korean men, especially in the elderly population.

PURPOSE: To compare the accuracy of 16-slice multi-detector row computed tomographic arthrography (MDCTA) and magnetic resonance arthrography (MRA) for making the diagnosis and classification of labroligamentous injuries. MATERIALS AND METHODS: This study is a prospective series that used MRA and MDCTA to examine 23 patients who complained of shoulder instability. Two radiologists independently analyzed the MRA and MDCTA. The sensitivity, specificity, accuracy, positive and negative predictive values were calculated from the arthrograms and the arthroscopic findings. The images of MDCTA and MRA corresponded with the findings on arthroscopy. RESULTS: Both imaging modalities had the same sensitivity for detecting Bankart lesions (n=10, 90%) and posterior labral tears (n=2, 50%) on McNemar test (p=1.00). For superior labrum anterior-to-posterior (SLAP) lesions, 6 MRA cases and 4 MDCTA cases corresponded with the arthroscopic findings. The difference between the sensitivities of MDCTA (66.7%) and MRA (100%) was not significant (p=0.09). CONCLUSION: We suggest that the sensitivity of diagnosing labral lesions that induce shoulder instability is similar for MDCTA and MRA. MDCTA is effective for diagnosing and evaluating shoulder instability.

PURPOSE: To analyse and compare high-resolution CT findings of pulmonary tuberculosis with consolidation and mycoplasma pneumonia. MATERIALS AND METHODS: Twenty patients with pulmonary tuberculosis [confirmed by sputum culture (n=9) and bronchoscopic biopsy (n=11)] and airspace consolidation on high-resolution CT and 17 patientswith mycoplasma pneumonia, confirmed by serologic test, were included in this study. High-resolution CT findings were analyzed in terms of ground-glass opacities, distribution of consolidation, type of nodules, cavities, interlobular septal thickening, bronchial dilatations, bronchial wall thickening and pleural effusion. RESULTS: In patients with tuberculsis, average age was 33.5 years (range, 20-67) ; in those with mycoplasma pneumonia it was 32.5 years (range, 17-74). Segmental and subsegmental distributions were most common in both diseases ; the preferred site of consolidation was different, however ; for tuberculosis it was the upper lobes (13 cases, 65% ; bilateral involvement, 7 cases) ; for mycoplasma pneumonia it was the lower lobes (11 cases, 64.7%). Non-segmental (diffuse and random) distribution of ground-glass opacities were seen in two patients(11.8%) with mycoplasma pneumonia. Centrilobular nodules, branching linear opacities and alveolar nodules were not different in both diseases, but there were nodules above 10mm in 14 cases of tuberculosis and in only one case of mycoplasma pneumonia. Tree-in-bud appearances were seen in five cases of tuberculosis. Cavities without air-fluid level were noted in ten cases of tuberculosis. Other interlobular septal thickening, bronchial wall thickening, bronchial dilatation and pleural effusion were not different in both diseases. CONCLUSION: There was considerable overlap between high resolution CT findings of tuberculosis with airspace consolidation and those of mycoplasma pneumonia. The location of consolidation, type of nodules, and the presence of tree-in-bud appearance and cavities help in the differentiation of the two diseases, however.
