Chest CT is the most useful modality in the diagnosis of primary lung cancer, particularly in patients with recurrent pneumonia which are resistant to antibiotic therapy and in high risk age groups for cancer, The purpose of this examination is to assess the usefulness of CT in pneumonia types of lung cancer. The authors retrospectively analyzed 15 histologically proven cases of pneumonic type lung cancer, which had no evidence of primary lung mass, mediastinal lymphadenopathy or other metastatic lesion on piain chest radiography. On CT scan, a primary lung mass was identified in 13 patients(87%, bronchial obstruction was identified in 12 patients(80%), and metastatic foci was found in the bone(one patient), liver(one patient), and spleen(one patients). In Conclusion, CT scan is a useful method to detect the mediastinal lymphadenopathy or pulmonary mass and also should be the initial radiolographic procedure for diagnosis of lung cancer in patients with recurrent pneumonia on simple chest radiography.

Castleman's disease(Giant lymph node hyperplasia) is a pathologic entity of unknown etilogy, as attested to bythe number of names it has received, lymphoid hamartoma, angiomatous hamartoma, and giant lymph node, etc.Although the mediastinum is its most common location, it also occures in other areas of the body, usually wherelymph nodes are normally found. Authors have been experienced 2 cases of histologically porven Castleman's diseaseduring recent 3 years in Kyung Hee University Hospital, and present its radiological and pathological findings asmediastinal mass.

Journal of the Korean Radiological Society 1996;35(2):205-212
A lateral chest radiograph is frequently useful and sometimes decisive in detecting chest pathology. Certainparts, such as the posterior wall of the bronchus intermedius (PWBI) and subcarinal regions, can be evaluated onlyon lateral chest radiograph. The authors present and emphasize the findings of PWBI and subcarinal abnormalities. Abnormal PWBI, more than 3 mm thick, is seen in cases of minor degree of oblique position, pulmonary edema, inflammation, neoplasm and enlarged lymph nodes. It can also be seen in patients with subcarinal mass. The findings of subcarinal mass on lateral view are ill-defined increased opacity, fullness of the inferior hilarregion, doughnut sign, extra-density and thickening of the PWBI. Detection of changes in the PWBI and subcarinalregion may be the only diagnostic evidence of hilar and subcarinal disease and helps in its early detection priorto computed tomography.

PURPOSE: Spiculation pathologically correlated with irregular fibrosis, localized lymphatic spread of tumor, or an infiltrative growth pattern of tumor, and the spiculation was Observed in malignant mass. But the spiculation was also observed in benign mass, particularly in tuberculoma. We retrospectively reviewed the length of spiculation under the hypothesis that the length of spiculation could be one of differential diagnostic points between lung cancer and tuberculoma. MATERIALS AND METHODS: We studied thirty seven patients (27 men and 10 women) ranging in age from 35 to 80 years (mean, 60 years). Analysis of spiculation included (a) the number of spicules (b) the mean length of spicules (c) the mean length of the longest spicule (d) the percentage of the mean length of spicules to the longest diameter of mass (e) the percentage of the mean length of spicules to the shortest dia, meter of mass. RESULTS: The mean length of spicules of tuberculoma was 13.8 mm (S. D. 6.7) and that of lung cancer was 5.7 mm (S. D. 3.5). The percentage of the mean length of spicules to the longest diameter of tuberculoma was 63.6% and that of lung cancer was 13.7%. The percentage of the mean length of spicules to the shortest diameter of tuberculoma was 90.4% and that of lung cancer w~s 18.3%. CONCLUSION: It is hard to differentiate lung cancer from tuberculoma on the basis of the spiculation being present or not, but we suggest that the longer spiculation be more highly suggestive of tuberculoma rather than lung cancer. The length of spiculation may help us differentiate lung cancer from tuberculoma.

PURPOSE: To find the rebleeding factors in bronchial arterial embolization for treatment of hemoptysis, a retrospective study was performed. MATERIALS AND METHODS:Medical records, anglographic findings and embolic materials of 35 patients who had undertaken arterial embolization for control of hemoptysis were reviewed. The period of follow-up for rebleeding was from 3 to 32 months after arterial embolization. We investigated the anglographic findings of extravasation, neovascularity, intervascular shunt, aneurysm and periarterial diffusion. Neovascularity was classified as mild(numerable neovascularity) and severe(innumerable). RESULTS: Rebleeding occured in 15(43%) among 35 cases. Only two of 11 cases with no past episode of hemoptysis showed recurrence, while 9 of 15 cases who had more than three episodes did. Severe neovascularity were seen in 11 of 15 recurred cases, but seven of 20 non-recurred cases showed severe neovascularity. More than three anglographic findings representing hemoptysis were seen on 11(73%) among recurred 15 cases and seven(35%) among non-recurred 20 cases. The lesion was supplied by more than two different arteries on 8(54%) of the recurred cases, but only three(15%) of the non-recurred cases. Six of seven cases persistent neovascularity after arterial embolization were recurred. CONCLUSION: The history of repeated hemoptysis, severe neovascularity, variable anglographic findings, and post-embolization persistency of neovascularity were the factors related with the rebleeding after arterial embolization for hemoptysis. Careful and active arterial embolization are required on these conditions.
