A mediastinal mass was aspirated by fluoroscope-guided fine needle aspiration biopsy in a 47 years old female patient. The first aspiration smears were not diagnostic, because of hemorrhagic background and cell paucity. On the second aspiration, the smears were composed of some clusters of benign epithelial cells in hemorrhagic background. Cells were arranged in mostly solid sheets and tended to form glandular lumina in part. Their nuclei were round and vesicular. Nucleoli were not prominent. These findings were suggestive of benign glandular tissue, which was finally confirmed as mediastinal thyroid gland by open thoracotomy specimen.

PURPOSE: The purpose of this study was to determine the role of CT and MR imagings in the diagnosis aortic dissection and differentiation between the true and false lumen. MATERIALS AND METHODS: We retrospectively studied forty patients with aortic dissection(AD) diagnosed imagings or surgery. Of the forty patients, 19 were examined with only CT, 14 with CT and MR, and 7 with MI~: Our points of view were(1) the classification of AD according to configuration of intimal flap by cross-sectional imaging, (2) differentiation between the true and false lumens, (3) the course of the false lumen, and (4)! detectability of the origin of major branch vessels of the abdominal aorta. RESULTS: The classification by corss-sectional imaging were crescentic(65%), circumferential(15%), flat(12%), and irregular(8%) type, in which false negative diagnosis was made in 1 case of crescentic and circumferential type, respectively. In 2 case of flat type and 1 case of irregular type, the differentiation between the true and false lumen was impossible with CT. The course of the false lumen in descending thoracic aorta revealed countrclock wise rotation(66%), clockwise rotation(5%) or fixed(29%) apperance. MR imaging was superior to CT in the detection of the origin of major branch vessels of the abdominal aorta. The determination of the origin of major branches of abdominal aorta arising from the true and false lumen were impossible in 2 cases in which only CT was done. CONCLUSION: Diagnosis of crescentic and circumferential types of AD with narrow and thrombosed false lumen was problematic in both CT and MR with no difference of diagnostic accuracy between the two modalities. The differentiation between the true and false lumen was difficult in flat and irregular types with only CT. Therefore, when surgical treatment is considered as in type B aortic dissection, MR imaging is recommended in order to determine the origin of major branch vessels.

OBJECTS: There was a trend to perform fusion and instrumentation in spinal stenosis surgery, because of extensive decompression and instability. However, the introduction of microscope in spine operation can minimize the range of excision of anatomical structure and reduced the decompressin level in the multiple lesions and the incidence of spinal fusion. The purpose of this study were to assess the outcome of this procedure in 3 years follow up and to identify the clinical features of the patients and technical aspects of the operation that were associated with a poor outcome. MATERIALS AND METHODS: Twenty-one patients were identified as having had a microscopic decompression without arthrodesis, for degenerative lumbar spinal stenosis over 60 years or their who had osteoporosis with Saville's index 2 or higher. The follow up period was more than 3 years. The clinical results was evaluated by Kim's criteria. RESULTS: Eleven cases were above good results in two levels involved 14 cases, 2 cases above good results in three levels involved 5 cases and 1 case above good results in four levels involved 2 cases. In the cases of affected duration, 7 cases are less than 1 year or more than 5 years each 6 cases and 2 cases were above good results by the criteria. We concluded that the long-term outcome of decompressive surgery in the elderly is good; it does not differ from that reported for younger patients . CONCLUSIONS: Selective microscopic decompression is one of the effective method for the elderly patients or patients with osteoporosis in addition to multiple stenotic lesions.

This study was undertaken at the department of Obstetrics and Gynecology, Chonnam University Medical School, to investigate the association between some of the risk factor and the incidence of intrauterine fetal growth restriction(IUGR). The studied population was selected from patients who admitted at Chonnam University Hospital during January, 1992 through May, 1997, with following criteria, Korean, singletone pregnancy with live birth and known gestational weeks with 28 or more. And then, the risk factors were analyzed in terms of maternal factor, placental factor, and fetal factor. The following results were obtained. 1) The incidence of IUGR was 6.1%. 2) The incidence of IUGR was higher at young aged mother and nullipara. 3) Only 39.1% of etiologic factors for IUGR was found to have known causes. According to the risk factors for IUGR, hypertensive disorder during pregnancy, anemia, cardiac disease, leukemia, and pulmonary tuberculosis were associated with increased incidence of IUGR. 4) The relative risk of IUGR was much higher in neonates born with congenital anomalies. 5) According to the placental causes of IUGR, placenta previa and placenta abruption showed some association with IUGR.

OBJECTIVE: To evaluate the perinatal prognosis of fetuses with a single umbilical artery. METHODS: From 1992 to 1998, nineteen cases with single umbilical artery(SUA) was observed in 8,704 deliveries at Chonnam University Hospital. RESULTS: Out of nineteen fetuses, thirteen fetuses with single umbilical artery were detected by antenatal ultrasonographic examination and six fetuses were detected after birth. The male to female ratio was 0.9: 1. Congenital malformations were observed in 8 babies(42.1%) and included leg deformity, esophageal atresia, imperforated anus, ventriculomegaly, meningocele, hydronephrosis, ventricular septal defect, joint contracture, cleft lip and palate, toe anomaly, imperforated anus, kyphosis, no urethra and testis, clubfoot, patent ductus arteriosus and rnild mitral regurgitation. Among 10 cases of karyotyping analysis three cases were diagnosed as trisomy 18. Fourteen fetuses(77.8%) showed growth restriction at delivery. Antenatal obstetric complications were hydramnios(n = 3), oligohydramnios(n =2), and severe preeclampsia(n = 3). CONCLUSION: Careful ultrasonographic evaluation for the identification of a SUA is necessary because of its frequent association with congenital anomaly, growth restriction and cytogenetic abnormality.
