1. Chest wall elastofibroma
All the choices provided are extraparenchymal lesions, but, among the possibilities listed, only choice “1” does not arise from the pleura. Furthermore, chest wall elastofibromas typically arise posteriorly from the chest wall connective tissue, typically in the subscapular region, and are not detectable at chest radiography. All the other choices may produce a mass-like extraparenchymal process similar to what is seen at this patient’s chest radiograph.).
The patient underwent thoracic ultrasound (Figure 2) for further characterization of the chest radiographic findings.
