As part of her care, a low-dose computed tomography (CT) scan for lung cancer screening was performed, revealing a 3.0 x 2.8 x 1.8-cm spiculated mass in the left upper lobe (Fig. 1A). Repeat CT approximately six months later showed marked improvement in the lesion (Fig. 1B). Serial CT scans thereafter showed continuous improvement with what appeared to only be residual scarring as far twenty-two months from initial diagnosis (Fig. 1C).
