1.Significance of a postenhancement computed tomography finding in liver cirrhosis: in view of hemodynamics
Journal of the Korean Radiological Society 1985;21(2):262-267
We observed a significant sign in postenhancement CT of liver cirrhosis, that is visualization of portalvenous branches. During postenhancement CT scanning of liver, the portal vein can not be identifed in liverparenchyme in 84% of patients without known cirrhosis (including chronic active hepatitis). Two have the samehemodynamic changes in that there is diffuse fibrosis and resultant decrease in vascular bed. Visualization ofintrahepatic portal branches in postenhancement CT is because of decreased diffusion ability and portalhypertension.

Most of malignant melanoma of skin had occurred in transformation from benign nevi(Webster, 1944), especially most frequently from junctional nevi of them. which was characterized by flat surface, dark-brown color and hairlessness(Ackermen, 1948) Blumberg (1972) introduced five levels of hietologic invasion of malignant melanoma described by Clark et al. Morton(1970) reported various measures of treatment such as surgery combined with radiotherapy or with chemotherapy or with recent immunotherapy with good result. The authors recently experienced 24-yeas old male soldier patient with malignant melanoma on hypothenar region of right palm. The pathologic investigation including electronmicroscopical aspect was carried out and are presented. Treatment consisted of the resections of right axillary lymph nodes and the lesion in situ on the hypotherar region of right hand, pedicle skin graft to right hand from abdomen, and immediate postoperative immunotherapy with intradermal injection of 1.0 cc. of B.C.G. daily on extensor surface of both thighs in turn, which lasted for about 3 months duration to find good result.

After the stabilization using unreamed intramedullary interlocking nails for the management of fractures of the tibial shaft, a large percentage of patients whose fractures would proceed to delayed bony union may be subject to secondary surgical procedure. The purpose of this study is to determine whether ultrasound, through its potential early assessment of the presence or absence of callus at the fracture site, can be used to predict the need for secondary surgical procedure. Fourteen tibial fractures (5 open, 9 closed) were treated with unreamed interlocking intramedullary nailing. Radiographs were obtained to monitor the maintenance of reduction and fracture healing. The results of ultrasound studies were obtained at two-week intervals for 10 weeks postoperatively and read by a radiologist. In prospective study of 14 patients, tibial fractures treated with unreamed interlocking intramedullary nailing were analyzed from June 1995 to February 1997 and following results were obtained. 1. Ultrasound correctly predicted fracture healing in all 10 fractures that subsequently progressed to fracture union. 2. Of the 4 fractures that did not heal, ultrasound was able to predict delayed union before it was radiographically evident. 3. Ultrasound predicted fracture healing at an average of 42 days (range, 22-70 days). In comparison, the plain radiographs showed fracture healing at an average of 126 days (range, 70 - 180 days). In conclusion, the tibia was ideal for ultrasound study because of the thin overlying soft tissue. Furthermore, the presence of the intramedullary nail facilitated evaluation of the intervening tissue. And there were several advantages of ultrasound over other imaging modalities. It was noninvasive, easy to use, and painless method of evaluation that does not use ionizing radiation.

We report a case of pulmonary infarction probably related with Henoch-Schönlein purpura, which presented with purpura on both lower extremities in a 27-year-old woman. The purpura had developed 4 days previously and it had no itching or tend'erness. She complained of mild fatigue, chest tightness, but no dyspnea or hemoptysis. On routine examination, chest radiography showed a poorly defined nodular opacity on the left lung field, and it was diagnosed by a follow up chest CT as a pulmonary infarction secondary to pulmonary vasculitis.

Supracondylar fracture of humerus is the most common fracture about the elbow in children and much has been written about its treatment and the prevention of both Volkmann's ischemia with contracture and cubitus varus deformity. In a retrospective survey of 155 children with supracondylar frscture of the humerus, 63 cases were found to have sufficient clinical and retrospective data to classify the fracture. 1. The average age was 6.5 years ranged from 1 year 3 months to 14 years and sex ratio was 2.2: 1(M:F) 2. 62 cases(98.4%) were extension type and 1 case(1.6%) was flexion type. In extension type, displacement was posteromedial 30 cases(47.6%), posterolatera117 cases(26.9%), posterior 10 cases(15.9%) and undisplaced 5 cases(7.9%). 3. Fracture level was divided into 3 Groups. Trans-olecranon fractures were 47 cases(74.6%), proximal to olecranon fractures were 11 cases(17.5%) and distal to olecranon fractures were 5 cases(7.9%). According to age distribution lower age group involves the distal part and higher age group involves proximal part. 4. Transverse fractures were 39 cases(61.9%) and oblique fractures were 24 cases(38.1%). In oblique fracture, postero-anterial oblique fractures were 19 cases(30.2%), medio-lateral oblique fractures 3 cases(4.8%), and latero-medial 2 cases(3.2%). In oblique fractures redisplacements were more common in P-A oblique csse. 5. In the treatment of fracture, 31 cases(49.2%) were treated with closed reduction and percutaneous pinning, 26 cases(41.3%) were treated with closed reduction and splint immobilization, 3 cases(4.8%) were treated with open reduction and K-wire fixation, 3 cases(4.8%) were treated with skeletal traction. 6. Functional results according to degree of initial displacement was worse in some displaced(Grade II) cases, rather than total displaced (Grade IV) or displaced with rotation (Grade III) cases. 7. Complications in splint immobilzation method were cubitus varus deformity 2 cases, nerve injury 2 case, and in k-wire fixation method, nerve injury 5 cases and pin migration 1 case.

PURPOSE: To compare the suppressive effects in hepatocellular carcinoma patients of transhepatic arterial chemoembolization by the infusion of adriamycin-lipiodol emulsion and of this plus 10ml of cisplatin solution. MATERIALS AND METHODS: In a total of 151 cases, the frequency of intrahepatic recurrence was compared with follow-up angiographic findings after the first and second transhepatic arterial chemoembolization with adriamycin-lipiodol emulsion and adriamycin-lipiodol emulsion plus 10ml of cisplatin solution, respectively. RESULTS: Among 46 patients whose first single infusion was after mean 119 days, the recurrence rate was 22% ; for 42 who were given their first multiple infusion after mean 76 days this rate was 5% ; for 35 whose second single infusion was administered after mean 147 days, the rate was 34%, and among 28 whose second multiple infusion was after mean 110 days, the rate was 43%. CONCLUSION: During the first trial of transcatheter arterial chemoembolization with adriamycin-lipiodol plus cisplatin solution, hepatocellular carcinoma recurred much less frequently, but during the second trial with cisplatin, recurrence was not suppresed.

Most insects including the honeybee cause erythema and edema at the site of a sting in non-allergic individuals. This reaction usually resolves within a few days. However, in certain cases, the persistence of inciting materials in the cutaneous tissue may promote a local inflammatory foreign body reaction. Localized nodular lesions were seen in our two patients and erythemstous patches were present in one patient due to rarely encountered complications induced by retained sting materials. In these cases histopathology showed multiple foci of foreign body granuloma containing yellow refraetile material in the center surrounded by histiocytes and foreign body giant cells. The granulomatous skin lesions in these patients were treated with intralesional injections of triamcinolone acetonide and partial excisions of the nodular masses were performed.

PURPOSE: To evaluate the causative factors of the false positive CT findings of parametrial invasions of cervial cancer. MATERIALS AND METHODS: we analysed 17 parametria of 14 patients with the diseases staged over lib on CT, but confirmed to be under stage Ila on pathology. The CT findings were retrospectively reviewed, and compared with pathologic findings. RESULTS: The causes of false postive diagnosis of parametrial invasions on CT were prominent cardinal ligaments (n=12), vaginal fornix(n=3), and prominent uterine vessels(n=2). CONCLUSION: Familiarity with these CT finding may be helpful in avoiding false positive diagnosis of parametrial invasion in patients with uterine cervical carcinoma.

Evaluations of residual renal function and the therapeutic effectiveness in renal tuberculosis have largely been dependent on intravenous pyelogram or Contrast-CT scan, even though, exact renal function are not evaluated with there methads. 99mTc-DMSA is a radiopharmaceutical that is trapped in the functioning tubular cells of the kidney and therefore, quantitative renal function could be evaluoted by ineasuring the counts of renal radioactivity and concomittant evaluation of renal morphology could be passible with the analog imapes of the radioactivity. The authors retrospectively analyzed 99mTc-DMSA scans of 75 kidndys of 67 patients with confirmed renal tuberculosis. We classified the morphologies of tuberculous kidneys as 6 types. We classified the morphologies of tuberculous kidneys as 6 types such as the type with small cortical defect, with parenchymal ulcerocavernous lesions, ulcerocavernous fistula to pelvis, mass-like defects, contracted kidney with ureter visualization, and the type with nonvisualization of kidney, corresponding to the characters of renal tuberculous pathogenesis with abscess formation, ulcerocavernous fistula, and fibrosis, and correspondings to the renal anatomy with parenchyma, and pelvocalyceal collecting system. Their mean residual renal functions measured with 99mTc-DMSA uptake rates were 19.0%, 18.4%, 7.9%, 12%, 4.1%, 3.4% respectively.
