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.

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.

PURPOSE: To evaluate the MR findings of knee injuries in skiing and to explain the mechanism of injury with MR findings. MATERIALS AND METHODS: We reviewed MR findings of 18 patients with history of knee injuries in skiing. The MR images were evaluated retrospectively to identify the ligament injuries, bone lesions and meniscal injuries. RESULTS: Ligament injuries were seen in 16 patients, bone contusions in 16 patients, meniscal lesions in two patients. The most common group of injury was anterior cruciate ligament (ACL) and roedial collateral ligament (MCL) injuries with bone contusion on posterior lip of the lateral tibial plateau (LTP). The second common group of injury was isolated ACL injury with bone contusions on the lateral fernoral condyle (LFC) and posterior lip of the LTP. We considered that the mechanism of injury of the former group may be correlated with the valgus torque with secondary anterior displacement of the tibia and the latter group may be correlated with the pivot shift phenomenon. CONCLUSION: MR may play an important role in the diagnosis of knee injuries in skiing and its findings may explain the mechanism of injury.

We report 2 cases of pediatric DNTs which presented with intractable seizures and no other associated neurologic abnormalities. They showed typical appearance of DNTs on neuroimaging and histopathology. Most patients with DNT can be cured by surgical treatment with exellent outcome and do not need ratio- or chemotheraphy. This study indicates that it is quite important to consider DNTs as one of differential diagnoses in patients with intractable seizures especially when they present only with seizures without other neurologic symptoms.

Schizencephaly, first described by Yakovlev and Wadsworth in 1946, is a rare congenital anomaly characterized by gray matter-lined clefts that extend through the entire cerebral hemisphere, from the ependymal lining of the lateral ventricle to the subarachnoid space. Clinically, patients with schizencephaly present motor dysfunction such as hemiparesis, seizures, and variable developmental delay. Absence of septum pellucidum, gray matter heterotopia, polymicrogyria, and hypoplasia of optic nerves were also frequently found to be associated with schizencephaly. We experienced a case of open-lip schizencephaly in a one-day-old male infant with wide, tense fontanel, which was confirmed by MRI.

Postpartum hemorrhage is an important cause of maternal mortality and morbidity. Especially uterine atony is the most common cause of postpartum hemorrhage. Conventional method to control postpartum uterine atonic bleeding is based on the use of oxytocin and ergot preparations. Prostaglandin F2alpha analogue such as carboprost can be used to promote contraction when these agents fail to produce uterine contraction. Prostaglandin E1 analogue, misoprostol has uterotonic effect by oral or vaginal administration. They are used to induce labor and first or mid trimester abortion. In postpartum uterine atonic bleeding, misoprostols cannot be used via oral or vaginal route. Recently we have experienced that postpartum uterine atonic bleedings unresponsive to conventional methods were controlled by rectal misoprostols. So we report these cases with a brief review of literatures.

PURPOSE: This study was aimed to review findings of gray-scale ultrasonography and to assess the diagnostic value of the resistive index (RI) in patients with acute epididymitis by comparing with that in normal volunteers. MATERIALS & METHODS: Gray-scale ultrasonogram was reviewed in nine patients with acute epididymitis for echogenicity, size and reactive hydrocele. Normal values of resistive index (RI) were obtained in 20 epididymides from 10 volunteers (aged 20-28, mean 23.7). Nine patients of epididymitis (aged 18-67, mean 37.2) were examinated with color Doppler sonography and RI was measured at 11 sites on epididymal arteries. For the prediction of acute epididymitis, accuracy, sensitivity and specificity were calculated at the cut-off value of RI in 0.65 and 0.70. RESULTS: Gray-scale ultrasonography showed echogenicity that was variable among the 9 cases (hype- rechoic 2 cases, isoechoic 2, hypoechoic 5), enlargement of epididymis in 8, and reactive hydrocele in 8 cases. Normal volunteers displayed color Doppler signals in 14 out of 20. The range of RI in normal volunteers were between 0.64 and 1.00 (mean, 0.79 +/- SD 0.10). In patients with acute epididymitis, color Doppler signals were detected in all patients. The range of RI in epididymitis were 0.40-0.68 (mean, 0.56 +/- SD 0.10). At cut-off RI value of 0.65, accuracy was 88%, sensitivity 81.8%, and specificity 92.7%. At cut-off value of 0.70, accuracy was 92%, sensitivity 100%, and specificity 85.7%. CONCLUSION: In addition to the findings of gray-scale ultrasonography, resistive index and color flow changes are valuable in diagnosing acute epididymitis.
