Undifferentiated embryonal sarcoma(UES) is an uncommon malignant hepatic tumor that occurs in older children and young adults. Six cases of UES were reviewed to determine their characterisfic findings on sonography (US) (n=5), computed tomography (CT) (n=6), and angiography (n=2) US demonstrated a single large, echogenic mass with some anechoic spaces in each case. CT revealed a well demarcated hypodense mass with hyperdense septa of variable shape and thickness. Four cases showed enhancing peripheral rim and some solid portions at the periphery or adjacent to the septa. Follow-up CT scan in one case who had not been treated showed enhancing solid portion changed to hypodense areas. Angiography showed hypovascular or avascular mass. Familiarity with these radiological findings of UES of liver will be helpful in differential diagnosis of primary hepatic tumors of childhood.

We reviewed the magnetic resonance imaging (MRI) of intracranial teratoma to detect the characteristic findings. Five patients with intracranial teratoma were evaluated with MRI from January 1988 to December 1990. Four male and one female patients with age ranging from 6 to 14 years were surgicelly confirmed MRI was done with 2.0T superconducting system(Spectro 20000, Goldstar, Seoul) and gadolinium enhancement was done in 4 patients. We retrospectively reviewed the clinical, operative, pathologic, and radiologic findings. Intracranial teratomas showed fatty component, calcification and cystic component filled with sebum or serous fluid. Peripheral rim enhancement was seen in three and irregular enhancement in two cases. There were hydrocephalus in all teratoma, but neither surrounding edema nor surrounding tissue invasion was seen. Low signal intensity rim was noted around the solid component of all tumors and they were not enhanced. MRI showed multicomponent of intracranial teratoma including the solid and cystic component, and low singal rim which might be the characteristic findings of the intracranial teratoma.

BACKGROUND: The purpose of this study was to determine that the assessment of serum neuron specific enolase(NSE) could provide a reliable early predictor of neurologic outcome after cardiac arrest. METHODS: Prospective, observational study was performed from April 1996 to March 1998 at a university teaching hospital ED. Serum NSE concentrations were analysed twice at 24 and 48 hours after return of spontaneous circulation(ROSC). Neurologic outcome was categorized using cerebral performance category(CPC). RESULTS: Twenty-nine patients(16 were men) were enrolled during the study period. The mean age was 50.8 years. Nine(31%) of them showed good outcome defied as CPC 1-3, and 20(69%) patients showed bad outcome defied as CPC 4-5. In the good outcome group, the serum NSE was revealed 33.8+/-9.3 ng/ml at 24 hours, 34.0+/-4.73 ng/ml at 48 hours. While in the bad outcome group, it was 99.5+/-11.7 ng/ml and 114.6+/-15.8 ng/ml. The NSE at 48hr after ROSC was more prescise than that of 24hr. When the cutoff value of 50 ng/ml at 48 hr, the sensitivity was 82%, and specificity was 93%. CONCLUSION: This study suggest that the serum NSE may represent a valuable, noninvasive, and useful clinical tool for prediction of neurologic outcome after cardiac arrest.

OBJECTIVES: There have been several studies documenting the changing level of the conus throughout infancy and childhood, but there is only a little detailed study that documents the range of conus positions in a living adult population, especially in Korean, without spinal deformity. METHODS: we made a sequential study of magnetic resonance images of the lumbar spine to determine the variation in position of the conus medullaris in 650 living korean adults population without spinal deformity who checked MRI to identify the cause of low back pain. The study population consisted of patients over the age of 16 years. A T1-weighted, midline, sagittal image was reviewed for identifying the postion of conus. This location was recorded in relation to the upper, middle, or lower third of the adjacent vertebral body or the adjacent intervertebral disc. RESULTS: The study group consisted of 305 men(47%) and 345 women(53%) with a mean age 45.9 years(range, 16-79 years). The conus existed commonly at the middle third of L1(131cases, 20.2%), at the L1-2 intervertebral space(129cases, 19.8%), and the lower third of L1(123cases, 18.9%). The mean position of conus was the lower third of L1(range, middle third of T12 to middle third of L3). Conclusions:The mean position of conus was at the lower third of L1(range, middle third of T12 to middle third of L3). This results was same as that of foreign study. Our results of living korean adult population could allow for safe clinical procedures such as lumbar puncture, spinal anesthesia, and help to explain the differences among observed neurologic injuries from fracture-dislocation at the thoracolumbar junction.
