Case in brief
A 75-year-old woman with multiple comorbidities presented with hematochezia, abdominal distension, intermittent colicky pain, and weight loss. Colonoscopy identified a large mass in the ascending colon, and CT imaging confirmed ileocecal intussusception with ischemic changes. Emergency right hemicolectomy was performed, revealing moderately differentiated mucinous adenocarcinoma without lymph node metastasis. The patient's immobility likely contributed to her clinical decline.
What made this case unusual
This case highlights the rare presentation of mucinous adenocarcinoma as a lead point for colonic intussusception in an adult, which is not commonly reported.
Diagnostic / clinical pearl
Clinicians should consider underlying malignancies, such as mucinous adenocarcinoma, in cases of adult colonic intussusception, especially in patients with significant comorbidities.
Why it matters
Understanding the association between tumor biology and host factors, like immobility, can aid in recognizing and managing complex cases of intestinal obstruction.
