In the unusual manifestation of right upper lobe collapse confusing with mediastinal or parenchymal mass, both alteration of the pulmonary vessels and shifting pattern of the collapsed lobe to the periphery on supine positionare the key to the diagnosis of it rather than mediastinal or parenchymal mass. The mechanisms of these unusual manifestation s are obscure, however lobar torsion and gravity factor are considered to be a main process. Authors have experienced 2 cases of unusual manifestations of right upper lobe collapse due to bronchogenic carcinomaduring resent 2 years in Kyung Hee University hospital, and prsent radiologic findings.

A wedge shape compensating filter composed of aluminium was made to equalise the density of lung and mediastinum. Total 68 patients were taken chest tomograph with compensating filter and the radiographic findings were correlated with the pathologic, bacteriologic prove or the clinical course. This simple device was turned out to be very useful in certain disease categories, especially central type of bronchogenic carcinoma.

Analysis of our primary bronchogenic carcinoma is restricted to 65 cases that have been regarded as having satisfactory histological and cytological proof of diagnosis by bronchial washing and bronchos opic biopsy and they were primarily diagnosed by roentgenography. Of these 65 cases, 59 cases were diagnosed by bronchoscopic biopsy and 6 cases were proved by bronchial washing. In the sex incidence, there were 49 males and 16 females, The peak incidence of bronchogenic carcinoma was 41.5 per cent in the fifth decade, 30.8 per cent in the fourth decade, and 1.5 per cent in the second decade. Cough, sputum raising, chest pain, and dyspnea were the most common complaints but three patiens had no signs or symptoms. The pathological classification, metastasis and complication were discussed for these 59 cases. Radiological classification of lung cancer revealed the following types: central pneumonic form; central solid form; central infiltrating form; peripheral solid form; peripheral cavitary form. 86.2% was central hilar type and 13.8% was peripheral type. For distribution of these 65 cases, 60% showed right lung involvement and 40% showed left lung involvement.

Primary leiomyosarcoma of the lung is very uncommon, and fewer than 50 cases now have been reported. Primary leiomyosarcoma of the lung resembles bronchogenic carcinoma in its clinical presentation and radiologic appearance. However, the former has some differences; younger onset than bronchogenic carcinoma, polypoid endobronchial growth, few positive cytologic examination of sputum and unusual lymph node metastasis. We experienced a case of primary leiomyosarcoma of the lung.

Pseudohypopyon of tumor cells can be found in patient with intraocular tumor. This condition resembles true hypopyon of iridocyclitis. Paracentesis of the anterior chamber may be undertaken to find malignant cells. A 68 year old Korean man with bronchogenic carcinoma was found to have a tumor mass in the root of iris, pseudohypopyon and secondary glaucoma as. Anterior chamber tapping was failed to show tumor cells. Any inflammatory cell was not found in the anterior chamber tapping.

We reviewed the computed tomography (CT) of 32 patients with upper lobe collapse to assess the significance of small atypically redistributed pleural effusion (ARPE) in distinguishing the bronchogenic carcinoma (BC) form tuberculosis (TB). Upper lobe collapse was caused by BC in 21 and by TB in 11 of the 32 patients. Small ARPE was Present in 14 of 21 patients with BC and two of the 11 patients with TB, Among 16 patients with small ARPE, CT showd mediastinal invasion in 11 (69%) patients and mediastinal lymphadenopathyn 6 (38%). Our results suggest that small ARPE associated with upper lobe collapse can be used a an auxiliary sign in the differential diagnosis between BC and TB.

From Jan. 1983 to June 1984 in Yonsei University Medical College 17 patients received curative resectivesurgery due to bronchogenic carcinoma. The following results were obtained by comparing the CT findings to theoperative and histological findings of those patients. 1. The histological types of 17 cases of bronchogeniccarcinoma were squamous cell Ca. 8 cases, adenocarcinoma 7 cases, and undifferentiated Ca. 2 cases. The both ofthe undifferentiated type were confirmed by post operative histological study. 2. The lesions showing falsepositivity of mediastinal invasion are enlarged but have well circumscribed margins and separated lymph nodes. 3.In contrast, the prediction of hilar infiltration by CT gave only 25% sensitivity, 77.8% specificity and 52.9%accuracy. 4. For the clinical staging done by CT, only 47.1% were in accordance with the surgical staging. 5.However, CT is useful in selecting the patients who need invasive staging before abandoning curative resection andin suggesting the type of invasive staging according to the location of the lesion.
