Malignant fibrous histiocytoma is a rare malignant tumor of histiocytic origin, arising from either bone, or soft tissue. Six cases of malignant fibrous histiocytoma are presented with emphasis on radiographic features. Five cases are of primary bone origin and one of soft tissue. Ill-defined osteolytic bone destruction with no sclerosis and with no periosteal reaction is the principal radiologic feature of the malignant fibrous histiocytoma of bone. Therefore, malignant fibrous histiocytoma should be considered in differential diagnosis of primary intraosseous or extraosseous malignancies.

The first myelography with air was carried out by Walter Dandy in 1919, and the myelography with positive contrast medium was done by Sicard and Forestier in 1922. Since Pantopaque was adopted as a contrast material by University of Rochester group in 1944, it has been rapidly popularized. Although higher diagnostic accuracy has been made with a development of the diagnostic aids such as electromyography, discography, epidural venography and computerized tomography, myelography has been popularized in our country with electromyography. The authars have seen and studied 107 cases of herniated lumbar disc with respect to the diagnostic accuracy of myelographic examination from January, 1976 to December, 1981 at the department of Orthopedic Surgery, Yonsei University College of Medicine. The results were as follows: l. Of the 107 cases, 59 were found in the age of 20 to 40 years and the ratio of male and female was 2:l. 2. Fifty eight cases (54.2%) had no history of back injury, but 40 cases (37.4%) had sprain of the back and 9 cases had direct trauma history. 3. In all cases, plain X-ray and myelogram were taken. Among them 55 cases showed narrowing of intervertebral space in plain film, and 100 cases showed positive myelographic findings such as lateral indentation of dural sac (41 cases), hour-glass defect (30 cases), root sleeve defect (12 cases), block defect (10 cases) and combined defects (7 cases). 4. Sixty one cases which confirmed by operation, the most frequent level of disc herniation was in L4-5 space. Clinical diagnosis was correct in 57.4%, and myelographic accuracy was coincided with operative finding in 80.3%. 5. Twelve (19.7%) of the 61 cases showed discrepancy between myelographic and operative findings, and these 12 cases consisted of 5 cases of level discrepancy, 3 cases of false positive and 4 cases of false negative.

Xanthogranulomatous pyelonephritis, an uncommon chronic inflammatory renal disorder of middle-aged women, is rarely seen in childhood. A 10 year-old boy with focal type of this disease in upper and lower pole was experienced. Patient had a intermittent fever and right flank pain without palpable mass. The blood analysis only revealed ESR increase but no anemia, no leukocytosis. There was no history or signs of urinary tract infection or calculi. The urine analysis and culture showed nothing abnormal. An intravenous pyelogram, ultrasonogram, abdominal CT and selective renal arteriography only demonstrated a non functioning upper pole of right kidney. During operation, a gross finding and frozen section strongly showed xanthogranulomatous pyelonephritis and diagnosis was made on histological examination, After nephrectomy, there had been no evidence of disease recurrence during 2 years follow-up period.

PURPOSE: When the patients with both recurrent and primary pterygia, We performed conjunctival autograft transplantation for recurrent pterygium and bare sclera technique for primary pteygium. We then compared the recurrence of each case in order to find out the usefulness of each surgery and effective mothod of surgery. METHODS: We performed follow-up on 26 eyes of 13 patients for 14 months (mean); 8 patients (16 eyes) were female, and 5 patients (10 eyes) male. The mean age of the patients was 49.5 years ranging from 37 to 63. In the operation, all patients received with 0.02% Mitomycin C for 1 minute. RESULTS: Pterygium recurred in 3 of 13 eyes which underwent bare sclera technigue, and did not recur in 13 eyes undergoing conjunctival autograft transplantation, but there was no significant difference because of a small number of study cases (P=0.07). We found postoperative complications such as corneal fila-ment and conjunctival granuloma in the case of bare sclera technique; but none in conjunctival autograft transplantation. CONCLUSIONS: We recommend a conjunctival autograft transplantation with application of low concen-tration of Mitomycin C as a safe and effective method for recurrent pterygium or pterygium with high recurrence rate.

PURPOSE: Periventricular leukomalacia(PVL) is associated with the characteristic neurologic sequale of spastic diplegia or quadriplegia, and cortical blindness. So early diagnosis of PVL in the neonatal period is of importance because of the prognostic implications of this lesion. Novotny et al reported that Positive Rolandic Sharp waves(PRS) on the EEGs was a marker of PVL because most infants who had excessive PRS on their EEGs also had PVL on their neurosonography. PRS were present in most neonates at a time when neurosonography showed periventricular echodense lesions, prior to the appearance of cystic PVL. Therefore, the appearance of excessive PRS on the EEG is very useful for the early detection of PVL. The aim of this study is to assess the relationship between the PVL and PRS on the EEGs, to observe the appearance timing of PRS on the EEGs, and to evaluate the risk factors of later neurologic sequale. METHODS: Among the neonates admitted to the Sowha Childern's Hospital between 1989 and June 1993, 25 neonates with cystic PVL on neurosonography or CTscan were the study group. Control group were the age-matched 20 neonates who were admitted at the same time of study period. We reviewed the neurosonographic findings, EEG features, and charts retrospectively. RESULTS: 1) Excessive PRS were observed in 20 cases of study group(80%), whereas 1 case in control group(5%)(p<0.001). 2) The frequency of PRS was not affected by the abnormality of EEG background activity. 3) The frequency of PRS in a 10 minutes epoch was 14.5+11.1 in the study group, whereas 1.57+1.96 in the control group(p<0.001). 4) In most neonates, PRS were present at a time when the neurosonography showed periventricular echodense lesion or cystic PVL. 5) In a follow-up neurosonography, 12 among 17 neonates with localized PVL were normalized and only 5 cases had ventriculomegaly. Whereas, all of 5 extensive PVL had the sequale of ventriculomegaly or cerebral atrophy. 6) In a follow-up neurologic examination, the poorer sequale including spastic diplegia or quadriplegia was associated with the larger, the more extensive, and the subcortical PVL. CONCLUSIONS: 1) Excessive PRS were significantly more observed in the study group than in the control group(p<0.001). 2) The frequency of PRS was not affected by the abnormality of EEG background activity. 3) The prognosis of the neonates with PVL was depended on the size, extent, and location of the PVL rather than the presence or frequency of PRS.
