Giant lymphnode hyperplasias are an uncommon entity. They are difficult to image on plain film. The CTapearance of this condition has been described inrecent radiologic literature. In this case report, combination of ultrasonogram and CT permitted differentiation of other space occupying lesions from giant retroperitoneallymphnode hyperplasia.

The injuries to the ankle joint complex can cause not only bony fractures but also assoicated ligamentrupture. Understanding of the mechanism of those injuries is important for the radiologist to give moreinformation to the orthopedist to identify ligament injuries and then to fix the fractures. In 1948, Lauge-Hansendevised a classification of ankle fractures based on the position of the foot and direction of injuring force atthe time of injury. On the vasis of location and appearance of the fibular fracture, 4 type of injuries areidentified; pronation-abduction (PA), prnation-external rotation (PER), supination-adduction (SA), andsupination-external rotation (SER). 60 cases of ankle fracures treated at Kyung Pook, National University Hospitalfrom Jan, 1973 to Dec. 1982 were analized and classified. The results are as follows; 1. Male was more frequetnlyaffected than female and the sex ratio was 4:1. 2. The most commonly affected age group was 20's. 3. Right sidewas more frequetnly affected than left. 4. Among 4 types, the most common was SER type (33.3%) and next were PER(30.3%), SA(16.7%), and PA(13.3%) types.

Sonographic detection of ureteral jets entering the urinary bladder is a well-known procedure. Color Doppler ultrasound was used to image the ureteral jets in 28 patients with unilateral ureteral calculi proved by intravenous urography. Three major findings of ureteral jets were obtained in the affected ureter with a stone: less frequency (26 patients), weak reflection (20 patients), and lower grade in length (27 patients) that were significantly different from the unaffected side in the same patient. No significant differences were found between the ureteral jets and the degree of hydronephrosis or the location of a stone. In conclusion, these results suggest that ureteral jets should be checked routinely during the procedure of color Doppler ultrasonogram in patients with possible unilateral ureteral obstruction. Color Doppler examination of ureteral jets may be a important adjunct in routine pelvic ultrasonogram especially in patients who have absolute or relative contraindications of intravenous urography.

BACKGROUND: The measurement of nonspecific bronchial hyperreactivity is valuable for diagnosis and management of bronchial asthma. Methacholine or histamine is used for the pharmacologic provocation test. Usually a methacholine bronchial provocation test is performed by a dosing technique with counted number of breaths. A dosimeter is indispensable in the dosing technique. Recently a timed tidal breathing technique which dose not need an expensive dosimeter was introduced. We measured the degree of nonspecific bronchial hyperreactivity to histamine using a simple timed tidal breathing technique. METHOD: Forty two healthy volunteers, 12 patients with bronchial asthma(BA), 10 patients with rhinitis(RH) and 10 patients with upper respiratory infection(URI) participated in the study. The subject's nose was clipped and inhalation continued during tidal breathing for 2 minutes via a face mask. FEV1 was measured at 30 seconds, 90 seconds after inhalation and inhalation of next solution was continued until there was a fall in FEV1 of 20%. Histamine PC20 was defined as the concentration at 20% fall of FEV1 and it was obtained from the log dose-response curve by linear interpolation. RESULTS: Inhalation of serial dilution of histamine could be performed in all patients without significant side of effects. The geometric mean±standard deviation of histamine PC20 in healthy volunteers is 8.27±2.22mg/ml, BA group 0.33±3.02mg/ml, RH group 0.85 ±3.24mg/ml, and URI group 1.47±1.98mg/ml. CONCLUSION: Histamine bronchial provocation test using timed tidal breath method is a simple and suitable tool for management of patients with bronchial hyperreactivity.

Ultrasound studies of sixty five patients with thyroid mass histologically proven at KyungPook NationalUniversity Hospital from June 1983 to May were retrospectively analized. No specific sonographic characteristicsof thyroid mass lesions was found on the basis of histological diagnosis. Authors consider that ultrasound studymight be mere useful for detection and localization of a lesion, and guide to needle aspiration, monitoring thesize of a mass following therapy as well.

PURPOSE: To evaluate the indication for intracavitary Urokinase(UK) in the treatment of Ioculated pleural effusion. MATERIALS AND METHODS: We analyzed CT and US in 31 patients who were treated with intracavitary UK in Ioculated pleural effusion. In each patient, a single chest catheter (10-12F) was insected under imaging guidance. When the amount of drainage was less than 100ml/day, UK was instilled through the catheter until less than 50ml/day was drained. On follow-up chest radiographs of more than 1 month, we classified the results of treatment into 3 groups:(1) completely effective (lung expansion, over 80%);(2) partially effective (20-80%); (3) ineffective (below 20%) group. Sonographic pattern of pleural fluid was classified into anechoic, septated, and honeycomb appearances and the thickness of parietal pleura was measured on CT. RESULTS: Sixteen patients were completely effective, nine were partially effective, and six were ineffective. patients with completely or partially effective outcome had anechoic and linear septated appearance on had less than 4mm of parietal pleural thickness on CT. Of six ineffective patients, US showed linear septated in one patient and honeycomb appearance in five patients and the thickness of parietal pleura on CT was 3 mm in one patient, 4ram in two patients, 5mm in one patient, and 6mm in two patients. CONCLUSION: UK instillation through percutaneous catheter was an effective method in the treatment of Ioculated pleural effusion. However, we found near complete reaccumulation of pleural fluid when honeycomb appearance of pleural fluid on US or more than 5mm parietal pleural thickness on CT was observed, which might suggest that we should consider the other kinds of treatment method in those patients.
