注)エキスパートシリーズの肺は残念ながら途中で終わっています。

エキスパートがそれ以上のホームページアップを望まなかったからです。

なので私がそのとき習ったこととさらに文献をなどを引用し肉付けして

代わりに動画でアップしていきます。お楽しみに。

Key words: Thymoma, 胸腺腫、anterior mediastinal tumor, 前縦隔腫瘍, WHO classification, WHO分類、Masaoka classification, 正岡分類、胸腺癌, thymic cancer, Diffusion weighted image, DWI, 拡散強調画像

まとめ:黒色は非浸潤性胸腺腫、赤色はより浸潤性、紫色はより癌を示唆

  • 大きい
  • 被膜(より完全)、隔壁
  • 境界明瞭、不明瞭
  • 分葉状、不整
  • 出血、壊死、嚢胞性変化
  • 石灰化
  • 不均一造影効果
  • 造影効果が高いか否か
  • T2WI上不均一
  • T2WI上腫瘍内の低信号
  • 胸膜播種
  • 縦隔脂肪浸潤
  • 大血管浸潤
