Abstract:
Pulmonary mucinous adenocarcinoma (PMA) is relatively rare. On chest CT, it can be divided into two types: mass type and pneumonia type. Mass type PMA is more common and is difficult to distinguish from other nonsmall cell lung cancer. It is a solid or partial solid nodule or mass, predominantly located in the peripheral field of the lung with lobulation, spiculation, and more prone “vacuole sign”. Pneumonia type PMA has a poor prognosis and is more likely to develop into diffuse, multifocal and multilobular lesions similar to inflammatory manifestations, indicating dissemination along the airway. Typical signs include large areas of low density, low enhancement consolidation, and “dead tree sign”.
