Lung adenocarcinoma - a diagnostic challenge

Cavitary lung nodules are produced by a variety of diseases ranging from benign to malignant disease. According to the Fleischner Society, the pulmonary cavity is characterized by a gas-filled space, seen as a lucency or low-attenuation area, within pulmonary consolidation, a mass, or a nodule. Though the number and thickness of the wall of the cavity may help to differentiate causes, arriving at a diagnosis is challenging. Even though radiological findings will help to differentiate benign from malignant etiology, histopathology is needed for confirmation of diagnosis. Here, we describe a metastatic lung adenocarcinoma case presenting as multiple cavitary nodules.
