Aneurysmal benign fibrous histiocytoma(ABFH) is a relatively rare variant and has a distinctive histopathological features, that is collections of capillaries, foci of hemorrhage, siderophages, and foamy macrophages surrounding cleft-like and cavernous blood filled spaces in the tumor. But, in spite af the distinctive features, it is not infrequently confused with malignant melanoma, angiomatoid malignant fibrous histiocytoma, and vascular tumors such as spindle cell hemangioendothelioma, nodular Kaposi's sarcoma and angiosarcoma. We report a case of ABFH developed on the left upper extremity of a 41-year-old man.

The composition of triglycerides of the axillary sebaceous glands in 10 patient, with osmidrosis and 10 patients with hyperhidrosis was analyzed by high pressure liquid chromatography. Sebaceous glands were isolated and dissected by Kellum's method, and lipids were extracted by Folchs method. Individual triglycerides were separated by high pressure liquid chromatography and fatty acid composition of triglycerides was analyzed by gas-liquid chromatography. A number of individual triglycerides were identified: Fraction 1 consisted of dimyristoarachidonin, dilinoleioarachidonin, and myristol inoleioarachidonin, fraction 2 was trilinolein, fraction 3 was dilinoleioolein, fraction 4 was dilinoleiopalmitin, fraction 5 consisted of dioleiolinolein, dipalmitolinoleiri, and palmitooleilinolein. In osmidrosis patients, cornpositions of fraction 1, 2, 3, 4, and 5 were 5, 4%. 18.5% 29.5% 32.0% 14.1% of total triglycerides, respectively. In hyperhidrosis patients, cornpositions of fraction 1, 2, '3, 4, and 5 were,5, 9%, 20. 6%, 30. 9% 32. 1%, 14. 5% of total triglycericles, resectively. There were no differences in composition of triglycerides of sekaceous glands between osmidrosis patients and hyperhidrosis patients and hyperhi.frosis patients.

PURPOSE: To evaluate the usefulness of percutaneous catheter drainage (PCD) in patients who have abdominal abscesses or fluid collections. MATERIALS AND METHODS: We performed PCD for 165 abscesses and fluid collections in 148 patients. The follow-up periods in these patients ranged from 15 days to 42 months (mean, 274 days). The lesion sites were subphrenic space in 46 cases, liver in 33, perihepatic space in 20, pancreas or peirpancreatic space in 14, pelvic cavity in 13, and retroperitoneum in 13. We evaluated the success, failure, and recurrence rates, the causes of failure or recurrence, the mean duration of drainage, and the complications of PCD. RESULTS: Of the 165 cases, one hundred-fifty nine(96.5%) were successfully cured, Although a partial success could be achieved, 2(1.2%) cases were failed and 4(2.4%) were recurred. Multiloculation or fistula formation were the main causes of the unsullessful cases. The duration of drainage rainged from 2 to 605 days (mean, 1 days). Complications occured in 12 cases(7%) during or after procedures, which included fever and chill in 7, transgression of pleura in 2, bowel perforation in 2, and bleeding through catheter in 1. CONCLUSION: PCD is an effective and safe method for various abdominal abscesses or fluid collections.

Analyses were done on one hudred and twenty caaes of bleeding gastric ulcers diagnosed by emergency endoscopy for the past five years. The reaults are as the following: Much more cases were found in male than female and the most prevalent age group was 6th decade. The body of stomach along the lesser curvature was the most common bleeding site. No age related difference was noted in bleeding sites. Most common type of ulcer was in the round and shallow form. Five of six cases with exposed vessels showed atrophic changes in surrounding mucosa. Among the probable precipitating factors, analgesica, alcohols and certicosteroids were found in such order,

PURPOSE: The purpose.of this study was to characterize the enhancing patterns of hepatocellular carcinoma (HCC) on two-phase dynamic incremental liver scan with spiral CT. MATERIALS AND METHODS: Two-phase dynamic incremental liver scan using spiral CT was performed on 230 lesions in 107 patients with HCC. CT scanning was performed with a table speed of 13mm/sec and a section thickness of 10 mm;120 mL of contrast medium was injected intravenously with a automatic injector at the rate of 3mL/sec. CT scans were started 35 sec(early phase) and 3 min(delayed phase) after beginning injection of contrast medium. The tumors were divided into 2 groups according to size(< or = 3cm and > 3cm), the contrast enhancement patterns of HCCs and capsules in the early and delayed phases were analyzed in each group. RESULTS: Most of HCCs appeared as high-attenuating lesions in the early phase(75% in tumors smaller than 3cm and 61% in tumors larger than 3cm), and as low-attenuating lesions in the delayed phase(68% in tumors smaller than 3cm and 90% in tumors larger than 3cm). Forty-eight percent of HCCs smaller than 3cm and 58% of HCCs larger than 3cm were high-attenuating in the early phase and low-attenuating in the delayed phase. Thirty-two percent of capsules were low- or iso-attenuating in the early phase and high-attenuating in the delayed phase. Capsules were demonstrated in 22% in HCCs smaller than 3cm and 67% in HCCs larger than 3 cm(p <. 01). CONCLUSION: Two-phase dynamic scan with spiral CT is useful in the diagnosis of HCC because of a precise display of hemodynamic characteristics of HCCs.

PURPOSE: To analyze the MR imaging features of multiple sclerosis (MS) in spinal cord. MATERIALS AND METHODS: Nine MR (magnetic resonance) images of six patients with suspected MS were retrospectively evaluated in active phase (n=6) and inactive phase (n=3) before and after Gadolinium-DTPA administration. RESULTS: In all patients with clinically active phase, plaques of spinal cord appeared as high signal intensity on T2-weighted image with isointense cord swelling on Tl-weighted images. All lesions were enhanced on Gd-DTPA enhanced Tl-weighted images. The patterns of enhancement were nodular, circumferential rim-like, and segmental. On follow-up images in 3 patients who became clinically stable, all enhancing lesions disappeared. CONCLUSION: MR is a good modality in detection of spinal MS, and Gd-DTPA-enhanced MR is valuable in differentiating active MS from stable MS.

Bacterial meningitis results in significant neurologic dificits despite in spite of much effort in the treatment of the disease. This study was performed to determine the incidence of caustive organisms and to correlate between the organisms and computed tomographic (CT) findings with clinical outcome of bacterial meningitis in newborns and infants. We analyzed the brain CT and clinical records of 15 infants who had been diagnosed as bactrial meningitis by CSF culture. We found that the most common organisms were Group B streptococcus in neonates withou no neurologic complications in all but one and Hemophilus influenza in infants whose clinical outomes were poor in all except one. CT findings related with poor prognosis in this study were cerebral edema, basal cistermal obliteration & enhancement, and cerebral infarction on initial CT and ventriculomegaly on follow-up CT. We concluded that CT diagnosed intracranial complications of bacterial meningitis well and could contributed to better treatment of bacterial meningitis.

The authors analyzed 30 patients whose celiac artery or its branches were dissected during the procedure of transcatheter arterial embolization (TAE) for hepatocellular carcinoma (HCC) and were followed up angiographically. The incidence of arterial dissection was 1.25%. The dissection occurred most frequently in the celiac artery (40% 12/30) and the proper hepatic artery(28% 7/30). The frequency of arterial dissection was affected by the status of the vessel and the experience of the operator. The follow-up angiography revealed complete recanalization in 40% (12/30), irregularity and narrowing of the lumen in 23% (7/30), pseudoaneurysm formation in 23%(7/30), and complete obstruction in 13% (4/30) of the cases. The rate of recanalization in the celiac artery was lower than that of any other arteries in our series. Recamalization to a certain degree without therapeutic intervention was observed in 72% of the dissected arteries enabling and contributing to subsequent successful TAE within 2 months in 78% of the patients with the dissection.

PURPOSE: We evaluated the clinical, plain radiographic, and anglographic findings of congenital vascular malformation of the soft tissue. METHODS AND MATERIALS: Retrospective analysis was performed in 36 patients. Pathological diagnosis was done in 25 patients by surgery and the others were clinically and anglographically diagnosed. On the basis of anglographic findings, we classified the lesions to three groups as arteriovenous malformation(AVM), hemangioma, and venous malformation. In pathologically proven 25 cases, we compared the anglographic diagnosis with the pathologic diagnosis. RESULTS: By anglographic classification, AVM was 13 cases, hemangioma 16 cases, and venous malformation 7 cases. The locations of the lesions were upper extremities in 14 cases, lower extremities in 20 cases, both extremities in 1 case, and back in 1 case. Clinical findings were bruit and thrill in 13 cases(12 AVMs, 1 hemangioma) and varicosities in 16 cases(11 AVMs, 3 hemangiomas and 2 venous malformations). The varicosities in AVM were pulsating nature, but not in hemangioma and venous realformation. The concordance rate of the anglographic and pathologic diagnosis was 100%(6/6) in AVM, 71%(10/14) in hemangioma and 60% (3/5) in venous malformation. CONCLUSION: We think that angiography is an essential study for accurate diagnosis and appropriate treatment of congenital vascular malformation.
