title: [Anatomo-radiologic definition of minimal interstitial silicosis and diagnostic contribution of high-resolution computerized tomography].
abstract: Minimal interstitial silicosis (MIS) is a histologic entity characterized by questionable radiologic findings--i.e., the p/p 0/1 and 1/0 classes of the International Labour Office (ILO) 1980 classification. Thus, the condition may be responsible for borderline radiologic findings ("suspect" phase of pneumoconiosis). In order to test an alternative method to conventional radiology (CR), HRCT was performed on 35 workers exposed to silica and with histologic diagnosis of MIS: HRCT scans were compared with posteroanterior chest radiographs by using the ILO classification. Histology was the gold standard. HRCT identified many more MIS lesions. Moreover, the superiority of HRCT over CR was also proved by its better correlation with pathologic findings. HRCT provided pieces of information which could not always be obtained by means of conventional chest films. Thus, HRCT can be considered the method of choice in MIS before transbronchial lung biopsy.
