We report a previously healthy 21\u2010year\u2010old man who presented with acute anal pain after a coworker directed a high\u2010pressure air jet toward his perineum through two layers of clothing. He was hemodynamically stable, with preserved anal sphincter tone and no rectal bleeding, but had widespread subcutaneous crepitus over the chest and abdominal wall and a tense, distended scrotum. Computed tomography (CT) revealed extensive air within the retroperitoneum, perirenal spaces, abdominopelvic fascial planes, and subcutaneous tissues of the chest, abdomen, perineum, and scrotum, together with intraspinal air consistent with pneumorrhachis; no discrete persistent rectal wall defect, large fluid collection, or fecal contamination was identified. No water\u2010soluble rectal contrast leak study was performed; therefore, an occult sealed luminal communication could not be entirely excluded. Endoscopy at a tertiary referral center showed only superficial mucosal abrasion without a visible perforation, and the patient was managed conservatively with bowel rest, rectal lavage, and broad\u2010spectrum antibiotics, recovering uneventfully. These findings suggest that extensive air dissection may occur through a sub\u2010endoscopic mucosal breach or transiently sealed microperforation. CT was essential for mapping the air distribution and excluding high\u2010risk features; in a stable patient without peritonitis, fecal contamination, or clinical deterioration, this supported cautious conservative management.<\/jats:p>","DOI":"10.1002\/ccr3.73291","type":"journal-article","created":{"date-parts":[[2026,8,8]],"date-time":"2026-08-08T05:30:13Z","timestamp":1786167013000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Extensive
