Bronchogenic carcinoma: Correlation of CT findings with the surgical and histopathological findings

Abstract

CT and HRCT how largely replaced radiological procedures such has bronchography and pulmonary angiography for evolution of parenchyma lung diseases. HRCT has enabled the delineation of lung parenchyma down to the level of secondary pulmonary lobule (Mayo R et al., 1987). Further advancement in CT Technologies by spiral CT and ultra fast CT have still consolidated the role of CT in evolution thoracic diseases. Spiral CT facilitate generation of 3D images of lung that or not degraded by respiratory motion and is much faster at acquisition time ensuring evaluation of lung during maximum vascular enhancements. In this study CT evaluation of 50 patients with either proven or strongly suspected bronchogenic carcicnoma based on chest radiographs, bronchoscopy, cytology of bronchial washings or pleural fluid, FNAC or clinical examination was done. The most common cell type in bronchogenic carcinoma was squamous cell carcinoma in 33 patient (66%) followed by adenocarcinoma Majority of the adenocarcinoma cell type are presenting as central masses than peripheral (18% v/s 6%).
