腹部放射線(画像)診断学において、
「Abdominal Radiology」誌がとても役立ちますよ、
ということを以前お話ししましたが、
最新号の「Volume 44, Issue 5, May 2019」から下記論文を紹介します。

Ischiorectal fossa: benign and malignant neoplasms of this “ignored” radiological anatomical space. (Abdominal Radiology, 2019, 44(5):1644–1674.)
ときどき坐骨直腸窩の病変に出会うので、役立つと思いますよ。

Acquired diverticular disease of the jejunum and ileum: imaging features and pitfalls. (Abdominal Radiology, 2019, 44(5):1734–1743.)
比較的珍しい小腸憩室の総説です。

Frequency and imaging features of abdominal immune-related adverse events in metastatic lung cancer patients treated with PD-1 inhibitor. (Abdominal Radiology, 2019, 44(5):1917–1927.)
今後、ますます出会う可能性のある、免疫チェックポイント阻害剤のPD-1阻害剤による腹部領域副作用に関する論文です。

Eighteen (13%) patients had radiologically identified abdominal irAEs (median 2.1 months after starting nivolumab; interquartile range 1.17–5.83 months); 16 patients developed enteritis/colitis (12 pancolitis, two segmental colitis, one enterocolitis, one enteritis), two hepatitis, one adrenalitis. One patient with hepatitis also developed colitis/enteritis. Radiographic abdominal irAE occurred after nivolumab therapy was discontinued in six patients before any subsequent therapy was started. IrAEs prompted nivolumab interruption and treatment with steroids in four patients (three colitis/enteritis, one hepatitis). Most common CT features of colitis/enteritis included mesenteric hyperemia (n = 15), bowel wall thickening (n = 13), mucosal hyperenhancement (n = 10), and fluid-filled colon (n = 9).
