PURPOSE: We studied CT findings of bronchioloalveolar carcinoma that manifestated varied clinical and radiologic characteristics. MATERIALS & METHODS: We studied presenting radiographic patterns and their characteristics and secondary findings of histologically proven 30 cases of bronchioloalveolar carcinomas on chest CT scan. RESULTS: Bronchioloalveolar carcinoma appeared radiologically as a solitary nodule(19 cases), consolidation (7 cases), and multinodules(4 cases). A solitary nodular type shows irregular or spiculated borders, peripheral or subpleural location, heterogenous density, pleural tags, pseudocavitation, and sometimes rim-enhancement of mass. A consolidation type shows air-brochogram, pseudocavitation and CT anglogram within homogenous low attenuated consolidated lung. Hilar and mediastinal lymphadenopathy as secondary findings of bronchioloalveolar carcioma appeared frequently(43.3%). Even in a solitary nodular form, hilar & mediastinal lymphadenopathy was noted in 36.8% and follow-up study in 6 cases showed lung-to-lung metastasis with 14.7 months in mean metastasis duration. CONCLUSION: It is difficulty in diagnosis of bronchioloalveolar carcioma with clinical or plain radiographic features alone because of theis variability. We found that CT scan can help the diagnosis of this tumor. We also found out that a solitary form of bronchioloalveolar carcioma as well as diffuse form does not have a good prognosis.

BACKGROUND: Recently elderly people have increased in Korea and increased demands of medical service. This study was carried out to identify diseases and health service utilization patterns of geriatric inpatients to provide better understanding and basis planning to meet the needs of expanding geriatric population. METHOD: We use data of `Patient Survey in Korea` in 1999 and analyzed characteristics of disease structure and utilization patterns of health care service of 54,013 cases of discharged patients aged 65 years or more. RESULT: The proportion of the elderly in total discharged patients is 14.7%. Male to female ratio is 1:1.3 and most common age group was between 65 and 69 years old. 84.2% of elderly patients were admitted at secondary or tertiary health care facilities. The most common disease in geriatric inpatients is malig- nancy in male and vascular disease in female. The average duration of hospitalization is 14.2 days. They stay longer than the nation wide average hospital length and stay longest when they are admitted by mental and behavioral disorders. CONCLUSION: Geriatric patients are admitted mostly with chronic degenerative diseases such as neoplasm and vascular disease. Elders prefer to be admitted to tertiary hospitals and oriental hospitals. They stay more in hospital.
