Schwannoma is a rare intramedullary tumor. There has been no reported case about interval aggravation on follow-up MR imaging. We report initial and follow-up MR findings of a thoracic intramedullary schwannoma with syringomyelia and edema in a patient without neurofibromatosis. Intramedullary schwannoma should be included for differential diagnosis of intramedullary tumor even though followup MR imaging shows interval increase in size of the tumor and extent of associated edema to mimic malignancy.

Although evolution and time course of ischemic brain infarct should be a matter of interest to investigators in the research of brain ischemia as well as traumatic brain injury, few papers have ever been reported. Authors observed quantitatively sequential changes of infarct size and regional cerebral blood flow(rCBF) to assess the evolution of focal ischemic brain infarct in the rat following left MCAO. Fifteen rats, weighting 250 g to 370 g, were used in this experiment. The experiment animals were divided into three groups: 6, 24 and 48 hours groups(HG) after MCAO. The rCBF of bilateral caudate nuclei was measured by hydrogen clearance methods. Areas of brain infarction were delineated by tripheny-tetrazolium chloride(TTC) at the preselected 8 coronal levels of forebrain. The areas of brain damage were drawn on scale diagrams(x4 actual size) of forebrain and measured by a plannimeter. In the experimental groups, just after MCAO, rCBF of the ipsilateral caudate nucleus was reduced to 29.4+/-6.5 to 24.5+/-7.9 ml/100 g/min from the basal value of around 117 to 121 ml/100 g/min and showed a tendency of getting more reduced to 19.4+/-7.6 ml/100 g/min by 48 hours. The rCBF of the contralateral caudate nucleus was maintained in the basal value throughout the experiment. Comparing the total amounts of ischemic damage of 48 HG to those of 5 and 24 HG, the infarction size was significantly increased in cerebral hemisphere as well as cerebral cortex and caudate nucleus(p<0.05). But there was not any significant difference between 6 and 24 HG. The experiment provides evidence for the evolution of focal ischemic brain infarct without any further change of decreased rCBF. The data suggest that it is desirable to observe the change of pathologic findings by not less then 48 hours following the arterial occlusion in the study of ischemic brain infarction in the rat, particularly as long as ischemic damage is delineated by TTC.

Lymphangioma occuring in the gastrointestinal tract is a rare benign tumor, which is composed of lymphatic vessels of various size. A sharply demarcated smooth, soft, cystic submucosal tumor which is easily compressible and covered with normal mucosa is a characteristic eadoscapic feature. Recently, we experienced a case of lymphangioma in ascendmg colon and removed it successfully by colonoscopic snare polypectomy.

BACKGROUND: Leptin, the product of ob gene, is an important circulating hormone for the regulation of homeostasis of body weight and enegy expenditure. There was a previous reports that thyroid hormone is one of regulating factors of leptin gene expression in vitro. The aim of this study was designed to evaluate the role of thyroid hormone levels in the regulation of circulating leptin concentrations in human. METHODS: A total 16S subjects were studied; 76 patients with Graves disease, 49 patients with Hashimoto disease and 43 control sujjects. The correlation between thryoid hormone and leptin levels were analyzed and serum leptin levels were compared among the groups which was classified by thyroid functional status. Serum leptin concentratios were measured by radioimmunoassay. RESULTS: There were no significant differences in serum leptin levels between the groups of control, Graves disease and Hashimoto disease. The hypothyroid groups of Graves disease which was induced by excessive antithyroid drug treatment showed significant low levels(5.6 +/-2.8 ng/mL) compared to control(9.6 +/- 5.2 ng/ml) and thyrotoxic groups(10.0 +/- 5,0 ng/mL) CONCLUSION: The hypothyroid patients showed low levels of serum leptin concentrations it may indicate that thyroid horrnone play a role in the appropriate secretion of leptin in human.

Spinal hemangioma is the uncommon, slowly growing benign tumor that arises from the blood vessels and commonly located in thoracic spine. We have recently experienced a caseof capillary Hemangioma in intradural extramedullary space of thoracic spine level. The patient presented with a slowly progressive weakness of both lower extremities and hypesthesia below T6 dermatome. The plain X-ray films, thoracic spine myelography and CT scan disclosed an intradural mass at T5 level. The mass was surgically removed and conformed by histological examination.

Hypertensive intracerebral hematoma is a serious and potentially lethal condition. The indication of surgery in this hematoma is still controversial. Authors have treated 335 cases of hypertensive intracerebral hematomas which were confirmed by computerized tomography between July 1, 1982 and June 30, 1986. The hematomas have been classified according to their modes of extension on computerized tomography. The outcome was assessed on their basis of activity daily living. According to our study, moderate and severe types of putaminal hematoma cases have shown better results with surgery than conservative management. Mortality was 23.7 percent in surgery and 35.3 percent in conservative management.
