Representative computed tomography (CT) sections of the chest. The CT scan from January 2011 reveals few and small nodules, of which one is wedge-resected from the posterior upper lobe (a, arrow). Three years later, nodules became larger and spread to both sides of the lung (b). CT scans half a year later show a massive increase in size and number but also change of morphology in bilateral lung lesions (c, d). Representative image of the surface from the lower lobe of the right lung, taken during thoracoscopy: white, star-shaped lesions appear retracted into the lung tissue, reminiscent of lung metastases (e).
