Shuhei Hakiri, MD, Koji Kawaguchi, MD, Takayuki Fukui, MD, Koichi Fukumoto, MD, Shota Nakamura, MD, Kohei Yokoi, MD  The Annals of Thoracic Surgery  Volume 103, Issue 6, Pages e525-e527 (June 2017) DOI: /j.athoracsur Copyright © 2017 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Disease condition before chemotherapy. (a) Chest roentgenogram showed an abnormal shadow on the left side of the mediastinum. (b) Computed tomography revealed a tumor in the anterior mediastinum. (c) Positron emission tomography-computed tomography showed the intermediate accumulation (maximum standard uptake value of 4.1) of fluorodeoxyglucose heterogeneously within the tumor.

3 Fig 2 Disease condition after three courses of chemotherapy. (a) Chest roentgenogram showed an enlarged mass shadow. (b) Computed tomography also demonstrated that the tumor shadow had remarkably increased in size. (c) Positron emission tomography-computed tomography revealed that the maximum standard uptake value on the tumor had decreased from 4.1 to 2.5.
