1 Right Ventricular Outflow Tract Obstruction Due to Immunoglobulin G4–Related Disease 
Masaru Ishida, MD, Taichi Sakaguchi, MD, PhD, Shigeru Miyagawa, MD, PhD, Hiroyuki Nishi, MD, PhD, Yasushi Yoshikawa, MD, PhD, Satsuki Fukushima, MD, PhD, Ai Kawamura, MD, Takayoshi Ueno, MD, PhD, Hatsue Ishibashi-Ueda, MD, PhD, Yoshiki Sawa, MD, PhD  The Annals of Thoracic Surgery  Volume 103, Issue 3, Pages e235-e237 (March 2017) DOI: /j.athoracsur Copyright © 2017 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 (A) Coronal view on T1-weighted magnetic resonance imaging (MRI) showing the protruding mass in the right ventricular outflow tract (RVOT). Arrows indicate the tumor. (B) Short-axis view on T1-weighted MRI showing a homogenous mass in the RVOT. (C) Positron emission tomography showing increased fludeoxyglucose uptake at the RVOT. (D) Intraoperative surgeon’s view of the tumor. The Annals of Thoracic Surgery  , e235-e237DOI: ( /j.athoracsur ) Copyright © 2017 The Society of Thoracic Surgeons Terms and Conditions

3 Fig 2 (A) Macroscopic cut surface of the tumor. (B) Infiltration of extensive lymphoplasmacytes in fibrous background (hematoxylin and eosin, ×400). (C) The majority of plasma cells are positive for immunoglobulin G4 immunohistochemical staining (×400).

4 Fig 3 Time course of electrocardiography-gated computed tomography at the level of the reconstructed right ventricular outflow tract (RVOT). Asterisk shows the remaining tumor. White dashed line indicates RVOT and measurement of RVOT transection areas at (A) predischarge (area, 919 mm2), (B) 1 year after surgery (area, 768 mm2), and (C) 3 months after steroid treatment (area, 1014 mm2).
