Manifestaciones tomográficas de los subtipos del adenocarcinoma invasor de pulmón.

Introduction: Lung cancer is responsible for most deaths in the world, adenocarcinoma is the most common type. It is divided into pre-invasive lesions and invasive lesions with five subtypes: lepidic, acinar, papillary, micropapillary and solid. The importance of knowing its radiological behavior is that it would bring us closer to a more accurate diagnosis, taking into account that the therapeutic decision is based on the histological subtype. Objective: To know the tomographic manifestations of the different histological subtypes of invasive adenocarcinoma of the lung. Method: Descriptive, retrospective study. The image file, clinical file and pathology results of 113 patients with a diagnosis of invasive adenocarcinoma from 2015 and 2016 were reviewed. Results: The consolidation pattern was presented in the acinar and lepidic subtypes, the mass pattern for the solid, papillary, and micropapillary. All had hematogenous, lymphatic and mixed spread. Emphysema was the main associated finding, the lepidid was associated with ground glass. Exposure to cigarettes was 100% for the micropapillary subtype. Conclusions: The tendency of the tomographic presentation of the different subtypes of lung adenocarcinoma was identified, knowing the behavior we can get even closer to the diagnosis.
