Cronkhite-Canada syndrome is a rare, non-hereditary polyposis syndrome characterized by non-specific gastrointestinal symptoms accompanied by alopecia, cutaneous hyperpigmentation, and nail dystrophy. Characteristic endoscopic findings are diffuse sessile polypoid lesions with edematous mucosa. We report a case of a 44-year-old woman in whom intestinal ultrasound and CT revealed diffuse mucosal thickening and an ileocecal intussusception-findings that may not be pathognomonic but are highly unusual in adults. These imaging features served as critical red flags that directed the clinical suspicion toward Cronkhite-Canada syndrome and prompted timely endoscopic confirmation.
