Left) Axial NECT of an asymptomatic 90-year-old woman shows a left upper lobe nonsolid nodule that exhibits ground-glass attenuation. Note that pulmonary vessels ﬈ are visible through the nodule. (Right) Coronal NECT of the same patient shows to better advantage the spherical morphology of this nonsolid nodule ﬉. The nodule was unchanged on follow-up imaging. The differential diagnosis includes indolent malignancy, specifically lepidic predominant adenocarcinoma. 41 Approach to Thoracic Neoplasms Approach to Imaging Terminology (Left) PA chest radiograph of a 79-year-old man who presented with cough and chest pain shows a large, polylobular right upper lobe mass ﬈.

Radiologists who possess a substantial knowledge and understanding of imaging anatomy can analyze pulmonary abnormalities with respect to the underlying units of lung structure, such as the secondary pulmonary lobule. Characterization of neoplastic processes allows correlation with underlying histologic findings and preoperative identification of invasive behavior. Physiologic information obtained with scintigraphy and FDG PET/CT is essential in staging and restaging malignancies. For this reason, thoracic imagers today play an integral role in the multidisciplinary diagnosis and management of patients with malignancy.

Invasion Invasion is defined as infringement by intrusion or the spread of something that is usually harmful. In medicine, it refers to the entry into and proliferation of a pathogen or tumor. In the setting of neoplastic disease, it denotes an aggressive biologic behavior that allows it to intrude into and proliferate within previously normal tissues or structures. Imaging allows identification of this property by visualizing the lesion in question growing within another organ or tissue. Vascular invasion is characterized by visualization of the neoplasm within the vascular lumen usually on contrast-enhanced, crosssectional imaging, whereas skeletal invasion may manifest with destruction of the normal bone that can be visualized with radiography or more advanced imaging.
