PURPOSE: Cerebrovascular disease in children is more common than was once recognized and the etiology and prognosis of the disease in children are quite different from those of adults. Recently according to medical reports and clinical experiences, the incidence of childhood cerebrovascular disease is increasing in Korea. To clarify the clinical features of childhood cerebrovascular disease and to analyze its prognostic factors, retrospective study was perinatal problem, trauma or hypoxia. METHODS: We reviewed clinical records of the patients who had admitted to Seoul National University Children's Hospital during 5 years from Jan. 1989 to Dec. 1993. RESULTS: There were 82 cases(66.8%) of ischemic cerebrovascular disease as well as 41cases(33.3%) of hemorrhagic cerebrovascular disease. Various predisposing causes were known in 108 cases(87.8%); vasculopathy was frequent in ischemic group while hemato-oncologic disease was frequent in hemorrhagic group. The presenting symptoms and signs of childhood cerebrovascular disease were seizure, motor paralysis, headache, altered consciousness, etc. Transient ischemic attack and bulbar palsy were relatively common in ischemic group while ltered consciousness was more frequent in hemorrhagic group. The overall mortality of childhood cerebrovascular disease in this study was 11.4%, and deaths were frequent in hemorrhagic group(24.4%) than in ischemic group(4.9%) (p<0.005). Patients with a hemato-oncologic disease as a predisposing cause, and with an alteration of consciousness as a presenting sign were at increased risk for death (p<0.0005). Only 37 cases(33.9%) of the 109 patients surviving stroke were recovered completely while 72 cases(66.1%) had one or more residual deficits. Residual deficits occurred more often following ischemic stroke(71.8%), than after hemorrhagic stroke (51.6%), and complete recovery vice versa. Motor deficit was the commonest of the residual deficits. But the majority of motor deficits were mild and disability in fine motor control is common. Unlike in adults, seizure, mental retardation and learning disability were common as residual deficits in children. CONCLUSIONS: Considering above results childhood cerebrovascular disease is not so rare in Korea. And the clinical features and prognosis of cerebrovascular disease in children were somewhat different from those in adults. Since the outcome of childhood cerebrovascular disease is not so good, further exact and inclusive studies on this subject are required for early diagnosis and treatment which are important in decreasing mortality and morbidity of the disease.

Chordoid glioma is a rare, low-grade brain neoplasm typically located in the third ventricle. Herein, we report an unusual case of histologically confirmed chordoid glioma located in the pituitary fossa and suprasellar region, not attached to the third ventricle. A 57-year-old woman presented with a 2-month history of headache and visual disturbance. Magnetic resonance imaging revealed an ovoid mass in the pituitary fossa and suprasellar region, compressing the optic chiasm without involvement of the third ventricle. The tumor showed low signal intensity on T1-weighted images and iso- to high signal intensity on T2-weighted images, with strong and homogenous contrast enhancement. Subtotal resection was performed via the transcranial approach, and the patient subsequently received adjuvant gamma knife radiosurgery. However, the residual mass showed disease progression 5 months after the initial surgery.

Inguinal herniorrhaphy is the most frequent general surgical operation performed by pediatric surgeons, but some complications can usually be attributed to inappropriate approach and traumatic dissection. We experienced a case of acute renal failure due to bilateral ureter injuries after bilateral inguinal hernia repairs. The patient was a 3 month old male infant who presented as anuria and generalized edema after bilateral herniorrhaphy and was treated with peritoneal dialysis for 2 weeks. After 4 days of peritoneal dialysis, general conditions and symptoms were improved, but anuria persisted for 2 weeks. We performed IVP and abdominal CT. Both studies showed abnormal dye accumulation in peritoneal cavity. Ureteroneocystostomy on right and segmental resection of ureter and end to end anastomosis of left ureter were done without any complications. He has been doing well and has had normal kidney function. Therefore we report a case of acute renal failure due to bilateral ureter injuries after both inguinal herniorrhaphy with a brief review of literatures.

OBJECTIVES: Chromosomal anomalies are common disease entity among genetic diseases. But there are scanty reports about the status of chromosomal abnormalities in Korean. In addition, the comprehensive multi-center study of chromosomal abnormalities in Korean has never been performed. METHODS: We have collected 1,793 cases (394 abortuses; 198 chorionic villi; 1,060 amniotic fluid cells; 141 fetal blood), which showed abnormal karyotype results from twenty three cytogenetic centers in Korea from the year of 1977 to 1999. RESULTS: In abortuses, numerical chromosomal abnormalities was 85%, and structural abnormalities was 13% and the most frequent anomaly was trisomy 16. In chorionic villi, numerical anomaly was 60.0% and structural anomaly was 31.3% and the most frequent karyotype was Down syndrome. In amniotic fluid cells, structural anomaly exceeded the number of numerical anomaly and the most frequent anomaly was Down syndrome. In fetal blood, numerical anomaly was 63.8% and the most frequent karyotype was trisomy 18 (23.4%) CONCLUSIONS: This may be the first comprehensive and multi-center study in Korea. The proportion of the abnormal karyotypes in each specimens was different from each other. Based on this study, the more comprehensive study should be performed to all the Korean population.

PURPOSE: The purpose of this study to access MR findings of the lipomatous soft tissue tumor based on histopathologic correlation and its predictability of the histopathologic diagnosis. MATERIALS AND METHODS: We retrospectively analyzed the MR findings and photomicrographs of 9 patients with histopathologically proven lipomatous soft tissue tumors as follows;classic lipoma(4), fibrolipoma(1), lipoblastoma(2), atypical l ipoma(1) and well-differentiated liposarcoma(1). RESULTS: All cases of lipoma showed the same signal intensities as subcutaneous fat which is composed of mature fat cells. Linear low signal intensity lesions corresponded to fibrous connective tissues within lipomas. Two cases of lipoblastoma showed heterogeneous signal intensity with areas of high signal intensity brighter than subcutaneous fat on T2WI, corresponding to myxoid matrix of cytoplasm of immature lipoblasts, and the areas of myxoid degeneration within tumors. Both atypical lipoma and liposarcoma showed heterogeneous signal intensity with ill-defined margins due to presence of lipoblasts and infiltration to adjacent muscle bundles. CONCLUSION: MR image findings were well correlated with histopathologic findings of lipomatous soft tissue tumor, especially with maturity of fat cells and the signal intensity of mesenchymal components within the tumors. MR may predict the pathologic diagnosis of lipoblastoma by presence of myxoid degeneration within Ihe tumor, but atypical lipoma and liposarcoma revealed similar MR findings.
