Description
Susanna Li and Cameron Law report a case in 2026 of benign pulse granulomas that mimicked cancer spread on scans in a colorectal cancer patient. Pulse granulomas are a rare foreign body reaction marked by hyaline rings. They are usually found in the mouth or lungs, rarely in the gut.
The 72-year-old patient had countless glowing nodules across the abdomen on staging scans, suggesting metastases. Laparoscopy and biopsy instead showed pulse granulomas, likely tied to a prior bowel perforation. His cancer was staged without distant spread after colon surgery. The authors urge biopsy confirmation before denying curative treatment.
