Probably the Mycobacterium avium Complex around the Staple Line Exacerbated after Radiation Therapy

Figure 1

Chest computed tomography images. (a) A part-solid GGN on the middle lobe of the right lung. This portion of the GGN invades the upper lobe. (b) Three years and two months after the lung surgery, a mass emerges adjacent to the staple line. (c) Fluorodeoxyglucose PET-CT. The maximum standardized uptake value is 2.64. (d) Two months after the end of radiation therapy, ground-glass attenuation surrounding the mass and an increase in mass size are detected. (e) Five months after the end of radiation therapy, the mass shows continuous growth. (f) Five months after the end of radiation therapy, contrast-enhanced CT showed internal low absorption suspected of necrosis.
