While typically reported in the oral cavity and lungs, reports on extraoral gastrointestinal manifestations are limited. We present a case on a 72-year-old gentleman with a history of bowel perforation who was found to have a splenic flexure adenocarcinoma on surveillance colonoscopy. Staging imaging showed innumerable fluorodeoxyglucose-avid peritoneal nodules, with concerns of metastatic disease. Diagnostic laparoscopy and peritoneal biopsy found pulse granulomas. The patient had a left hemicolectomy and a final staging of T3N1M0 adenocarcinoma without distant metastases. This case demonstrates pulse granulomas as a rare but relevant mimic of peritoneal metastatic disease in colorectal cancer. Pulse granulomas should be a differential diagnosis of peritoneal nodules in patients with previous mucosal injury. Histopathological confirmation must be pursued to prevent unnecessary surgical intervention or excluding patients from curative treatment.<\/jats:p>","DOI":"10.1093\/jscr\/rjag826","type":"journal-article","created":{"date-parts":[[2026,9,4]],"date-time":"2026-09-04T11:33:08Z","timestamp":1788521588000},"source":"Crossref","is-referenced-by-count":0,"title":["FDG-avid pulse granulomas mimicking peritoneal metastases in colorectal cancer: a case report"],"prefix":"10.1093","volume":"2026","author":[{"given":"Susanna","family":"Li","sequence":"first","affiliation":[{"name":"School of Clinical Medicine, UNSW Sydney , Randwick, NSW ,","place":["Australia"]},{"name":"Department of Colorectal Surgery, Prince of Wales Hospital , Randwick, NSW ,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cameron","family":"Law","sequence":"additional","affiliation":[{"name":"Department of Colorectal Surgery, Prince of Wales Hospital , Randwick, NSW ,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,9,18]]},"reference":[{"key":"2026091808203046000_ref1","doi-asserted-by":"publisher","first-page":"121","DOI":"10.1007\/s00784-009-0322-0","article-title":"Pulse or hyaline ring granuloma.
