@Congenital peritoneal fossae and aperturesに関連した内ヘルニアのreview(Abdom Radiol 2021;46:1825–36.)
- 先天性内ヘルニア
- Congenital fossa
- left paraduodenal: fossa of Landzert; IMVの背側
- right paraduodenal: fossa of Waldeyer; SMVの背側
- foramen of Winslow: 門脈・IVCの間
- pericecal: 盲腸・上行結腸の背側
- sigmoid mesocolon; sigmoid mesocolonの下
- Intramesosigmoid: 1 layerのみのdefect
- Transmesosigmoid: both layersのdefect
- Through a mesentery
- broad ligament: one (pouch type) or both peritoneal leaves (fenestral type);
- the most reliable way to identify the broad ligament: linear, soft tissue-attenuation round ligament coursing between the uterus and internal inguinal ring.
- transmesocolic
- transmesenteric
- transomental: 1–4 layersあるがほとんどの症例では全4 layersを貫く。腹腔内の最前面で絞扼される小腸を認める場合などに疑われる。
- transmesosigmoid
- broad ligament: one (pouch type) or both peritoneal leaves (fenestral type);
- Web版のsupplementary materials (videos)では連続画像で見ることができる(が、なぜか多くは"The video is not available.")
@消化管 mucormycosis のreview(Abdom Radiol 2021;46:1837–45.)
- GIMMは最も頻度の低いmucormycosis (MM)であり、約7%だが、死亡率は~85%に及ぶ。
- 胃で最多という報告と、intestine(小腸+大腸)で最多という報告がある。
- 胃
- Emphysematous gastritis with Lack of wall enhancement
- Focal necrosis of gastric wall
- Focal or diffuse gastric wall thickening
- 小腸
- Diffuse dilatation of the bowel with wall thickening and altered enhancement
- Sharply defined segments of lack of enhancement
- Target sign: submucosal edema with increased mucosal and serosal enhancement
- 大腸
- Diffuse, focal or multifocal wall thickening
- Lack of visualization of portion and pneumatosis
- Mass like thickening
@Terminal ileumのNodular lymphoid hyperplasia(Abdom Radiol 2021;46:1846–54.)
- NLHとCrohn's terminal ileitis (CTI)で見た目は類似し得るが
- NLHでは炎症所見やリンパ増殖性疾患を伴わない
- よってNLHでは漿膜側は綺麗
- DWIや造影所見では両群に有意差なし。
