The pathogeoesis of papulonecrotic tuberculid had been thought to be the result of hernatogenous dissemination from primary tuberculous focus of other organs. But, today, the existence of papulonecrotic tuberculid as a rare cutaneous reaction to the Mycobacterium bacillus is questioned. Papulonecrotic tuberculid is, however, a real entity in underdeveloped countries where tuberculosis is more common. We report a case having papulonecrotie tuberculid associated with cervical lymph node tuberculosis confirmed by typical histopathology and by clinical response to antituberculous chemotherapy. This case supports Iden et al's view (1) that skepticism regarding the existence of papulonecrotic tuberculid is probably the result of the current decreased prevalence of untreated tuberculosis and consequently increased rarity of this entity.

Authors report the radiologic findings of two cases of multiple bile-duct hamartoma in the liver. Ultrasonography and computed tomography of the liver were performed in two female patients. In one patient, ERCP was performed. Ultrasonography and computed tomography showed scattered multiple hypoechoic and low attenuated lesions, measuring up to 2cm in both lobe and ERCP showed communication of these lesions with the biliary system. Multiple bile-duct hamartoma should be included in the differential diagnosis of multiple small cystic lesions in the liver.

Rhabdomyosarcoma are reportedly the most common soft tissue sarcoma occuring in childhood, but the biliary tree is a rare site of origin for this tumor. Recently we experienced a case of embryonal rhabdomyosarcoma of the biliary tree in a 30-month-old child. UItrasonography showed hypoechoic mass filling the dilated left. intrahepatic & extrahepatic bile ducts, and CT showed hypodense mass with heterogeneous enhancement after contrast infusion. Intraoperative cholangiography showed filling defects within the dilated left. intrahepatic & extrahepatic bile ducts. Postoperative MRI showed residual mass within the left. intrahepatic duct which was hypointense on T1WI and hyperintense on T2WI.

PURPOSE: We performed the retrospective analysis to find the outcome of external beam radiotherapy alone in advanced esophageal cancer patients. METHODS AND MATERIALS: One hundred and six patients treated with external beam radiotherapy alone between July 1990 and December 1996 were analyzed retrospectively. We limited the site of the lesions to the thoracic esophagus and cell type to the squamous cell carcinoma. Follow-up was completed in 100 patients (9 4%) and ranged from 1 month to 92 months (median; 6 months). RESULTS: The median age was 62 years old and male to female ratio was 104:2. Fifty-three percent was the middle thorax lesion and curative radiotherapy was performed in 83%. Mean tumor dose delivered with curative aim was 58.6 Gy (55-70.8 Gy) and median duration o f the radiation therapy was 53 days. The median survival of all patients was 6 months and 1-year and 2-year overall survival rte was 27% and 12%, respectively. Improvement of dysphagia was obtained in most patients except fo 7 patients who underwent feeding gastrostomy. The complete response rate immediately after radiation therapy was 32% (34/106). The median survival and 2-year survival rate of the complete responder was 14 months and 30% respectively, while those of the nonresponder was 4 months and 0% respectively (p=0.000). The median survival and 2-year survival rate of the patients who could tolerate regular diet was 9 rnonths and 16% while those of the patients who could not tolerate regular diet was 3 months and 0%, respectively (p=0.004). The survival difference between the patients with 5 cm or less turnor length and those with more than 5 cm tumor length was rnarginally statistically significant (p=0.06). However, the survival difference according to the periesophageal invasion or mediastinal lymphadenopathy in the chest CT imaging study was not statistically significant in this study. In a multivariate analysis, the statistically significant covariates to the survival were complete response to radiotherapy, tumor length, and initial degree of dysphagia in a decreasing order. The complication was observed in 10 patients (9%). CONCLUSION: The survival outcome for advanced esophageal cancer patients treated by external be am radiotherapy alone was very poor, In the treatment of these patients, the brachytherapy and chemotherapy should be added to improve the treatment outcome.

The purpose of this study is to evaluate the morphologic findings of the labrum and capsuloligamentous structures in the normal and unstable shoulders and to compare the effectiveness of double contrast arthrographic findings which were taken with supine and prone position. We reviewed the computerized tomographic arthrogram in 9 cases of normal shoulder and l3 cases of shoulder instability. We evaluated the shape of the labrum, the attachment of anterior capsule and the amount of capsular laxity. Capsular laxity was compared each others in normal, the unidirectional instability and the multidirectional instability. Among these materials, we simultaneously performed CT arthrogram with supine and prone position and evaluated which is more reliable and accurate. Scapular inclination was ahout 25 degrees in the supine position and ahout 60 degrees in the prone position. Normal glenoid labrum varied in size and shape, so its lack of a classic appearance might not indicate a labral tear. Variations existed in the anterior capsular attachment onto the glenoid. The anterior capsule was used to attach far away from the glenoid rim. but it might not indicate an anterior instability. With the prone position, the labral lesion took more excellent visualization due to the contrast coating on the glenoid labrum in both anterior and posterior. Anterior capsular expansion was seen well with prone position in anterior instability. In summary, for proper interpretation of the instability, awareness of the morphologic variations of the labrum and capsuloligamentous structure is important. CT double contrast arthrography with prone position has made a significant contribution to improving and easing the documentation of variety of anatomic abnormalities. Now we recommend the prone position in CT arthrogram for imaging glenoid labrum pathology in shoulder instability.

BACKGROUND: Overstimation of blood pressure(BP) by clinic measurements occur in about 20 to 30% of subjects(white-coat hypertension) who may, consequently, be misdiagnosed as hypertensives and received unnecessary medications. The clinical significance of white-coat hypertension and its effects on the cardiovascular wystem have not been studied systematically.This study was designed to evaluate the influences of white-coat hypertension and white-coat effect, defined as difference between clinic and ambulatory BP, on the LV mass and diastolic function. METHODS: LV mass index was calculated and LV systolic and diastolic function were assessed by the analysis of mitral and pulmonary venous flow velocity in 45 untreated essential hypertensives and 20 normotensives(NT). Ambulatory BP monitoring classified hypertensives as white-coat hypertensives(WCHT,n=20) and sustained hypertensives(SHT, n=25). RESULTS: 1) Left ventricular systolic indices were not different among the three groups. 2) Left ventricular mass inedx of WCHT(114.5+/-36.3g/m2) was similar to that of SHT(115.6+/-34.9g/m2) and was significantly greater than that of NT(86.5+/-37.7g/m2)(p<0.05). 3) Some of left ventricular diastolic parameters(isovolumic relaxation time, E/A ratio, A velocity, pulmonary systolic fraction, ratio of systolic to diastolic forward flow velocity) of WCHT and SHT were significantly different from those of NT(p<0.05), but there were no differences between two hypertensive groups. 4) Even though both systolic and diastolic white-coat effect in WCHT were significantly greater than those of SHT(o<0.05),white-coat effect did not influence on the left ventricular mass or function in both groups. CONCLUSION: An increased left ventricular mass and diastolic dysfunction in WCHT suggests that white-coat hypertension could not be considered as an entirely innocuous clinical condition.

PURPOSE: To evaluate the characteristics of the bronchiectasis in diffuse panbronchiolitis using HRCT. MATERIALS AND METHODS: We retrospectively studied 12 HRCT scans and two bronchography of 12 patients with diffuse panbronchiolitis(DPB). According to Akira et al., DPB was classified into four types: small nodules around the end of bronchovascular branchings(CT type I), small nodules in the centrilobular area connected with small branching linear opacities(CT type II), nodules accompanied by ring-shaped or small ductal opacities connected to proximal bronchovascular bundles(CT type III), large cystic opacities accompanied by dilated proximal bronchi(CT type IV). We compared the type and the extent of bronchiectasis, CTtypes of DPB, and pulmonary function test. RESULTS: Bronchiectasis was defined in 12 cases with the tubular type predominantly involving small and medium-sized bronchi. These bronchiectasis involved the proximal bronchi of the centrilobular lesions of DPB. Among eight cases of advanced DPB(CT type III & IV) which extended to both upper lobes, seven showed tubular bronchiectasis at the same area. Cystic bronchiectasis was shown in eight cases predominantly involving right middle lobe(n=7). There was no linear correlation between the values of pulmonary function test and CTtypes of DPB. CONCLUSION: Characteristic feature of the bronchiectasis in DPB is the tubular ectasis predominantly involving the small and medium-sized bronchi. DPB with associated tubular bronchiectasis can involve whole lung field in advanced cases. HRCT is useful not only to depict the findings of DPB but also to demonstrate the extent of lesion.
