Spontaneous spinal epidural hematoma is a rare entity. Various definitions for spontaneous epidural hematoma have been reported in the literature. The expression of nontraumatic spinal epidural hematoma seems to be less ambiguous and includes idiopathic hematomas and hematomas secondary to coagulopathy, vascular malformations, and tumors. We report three cases of nontraumatic spinal epidural hematomas observed from 1991 to 2000. The causes of the spinal epidural hematomas were not clear in two cases among them, but in the another one case, the cause was determined to be an acquired coagulopathy. We reviewed 24 cases reported in the Korean Journal of Neurosurgery and our three cases with particular emphasis on the various causes such as coagulopathy, vascular malformations and tumors. Among the 27 cases, numerous causes were detected such as three cases of vascular malformation, one case of anticoagulant treatment, five cases of combined lumbar disc herniation, two cases associated with pregnancy and postpartum, one case associated with hypertension, and one case associated with ossification of ligamentum flavum. No causes were detected in the ten cases. The authors reviewed the literature.

Clear cell sarcoma of tendon and aponeurosis is a rare malignant tumor. It occurs chiefly in young adults, predominates in women and is most common in the regions of the foot and ankle. We report a case of clear cell sarcoma of tendon and aponeurosis in s 22-year-old man. he pstient had had a asymptomatic, normal skin colored, relativerly hard, dome shsped nodule on the anterior chest for 6 months. Histopsthologic findings revealed uniform pattern composed of compact nests of round or fusiform cells which had clear cytoplasm and were surrounded by delicate framework of fibrocollagenous tissue, and the individual tumor cell had a fairly regular appearance of possessing round to avoid vesicular nucleus with prominent basophilic nucleolus. One year after surgical excision and post operative radiotherapy, there was no recurrence.

The pattern reversal visual evoked potential(PRVEP) and flash electroretinogram(flash ERG) were performed in 22 patients with optic atrophy. Patients with ophthalmologic problems other than optic atrophy or with systemic disorders were excluded from the analysis The results are as follows: 1. In the 41 eyes of patients with optic atrophy, 39 of them showed abnormal PRVEP, in which all the eyes had no consistent waveform except in one patient 2 eyes with delayed P1 latency. 2. 13 eyes were abnormal in both PRVEP and flash ERG but no eye was abnomnal in flash ERG only 3, Regarding the flash ERG examination, 13 eyes were abnomlal. Of these, there was a period of 1 to 2 years for 1 eye's disease, a period of 2 to 5 years for another eye' disease and after 5 years 11 eyes were diseased. Therefore, it showed that the longer the duration of disease lasted, the more flash ERG abnormalities developed. 4. The abnormalities of PRVEP haxe no significant relationship with the duration of the disease.

We treated a 66 year-old-male patient with non-traumatic spontaneous E. coli meningitis, whose cerebrospinal fluid showed turbid, and from which E. coli was cultured, and who had urinary tract infection and fatty liver disease which were thought to be predisposing factors to the meningitis. Gram-negative bacillary meningitis is a very rare condition after the neonatal period, and may be complicated by penetrating cranial injuries, neurosurgical interventions or such debilitating diseases as diabetes, liver cirrhosis, urinary tract infection, malignancy and alcholism, etc. It has a high mortality rate in spite of using various antibiotics.

Hereditary progressive dystonia develope in the first decade of ?life and is characterized by marked diurnal fluctuation of symptoms(dystonic postures and movements), i.e.symptoms aggrevated towards evening and alleviated after sleep. These symptoms and signs responded dramatically to levodopa. With the high incidence of familial cases this disorder is considers to be hereditary, but inheritance is not clear yet. Segawa regarded this disorder as a dystonia different from Parkinson's disease and other types of dystonic movement disorders, thereafter it has been reported under name of hereditary progressive dystonia with marked diurnal fluctuation.

PURPOSE: Zygomaticomaxillary complex(ZMC) fracture is one of the most common facial injuries after facial trauma. As ZMC composes major facial buttress, it is a key element of the facial contour. So, when we treat these fractures, the operator should have a concern with the symmetry to restore normal appearance and function. But sometimes, unfavorable results may occur. The aim of this study is to analyze the unsatisfied midfacial contour after ZMC fractures reduction retrospectively and to point out the notandum. METHODS: 369 patients, treated for fractures of the ZMC were included in the study. After the operation, such as open reduction and internal fixation(ORIF with titanium or absorbable materials), open reduction, and closed reduction, midfacial contour was evaluated with plain films and 3-dimensional computed tomography. And unfavorable asymmetric midfacial contours were correcterd by secondary correction and re-evaluated. Gross photographs were obtained at outpatient clinic. RESULTS: Total of 38 patients had got a facial asymmetry and among of them 24 patients were treated secondary revisional ORIF operations for correction of unfavorable result of after primary reduction. Two of them had received tertiary operations, three patients had got osteotomy more than after one year and six patients had got minor procedures. The etiology of asymmetry were lateral displaced simple fracture of arch(n=2), lateral displaced comminuted fracture of arch(n=6), comminuted arch fracture combined posterior root fracture(n=9), and communited arch and body fracture(n=12), severely contused soft tissue(n=9). After the manipulations outcomes were acceptable. CONCLUSION: To prevent the asymmetry in ZMC fracture reduction, complete analysis of fracture, choice of appropriate operation technique, consider soft tissue, and secure of zygoma position are important. Especially, we should be more careful about communited fracture of zygomatic body and lateral displacement, root fracture of zygomatic arch. Because they are commom causes that make facial asymmetry. To get optimal result, ensure the definite bony reduction.
