| Popis: | Introduction: Little is known about adult intussusception, but current evidence suggests that malignancy, polyps, and diverticula are usual etiologies. We present a case of adult ileoceccal intussusception secondary to carcinoid tumor. Case Presentation: A 53-year-old African American male presented with hematochezia and non-radiating constant left upper quadrant pain accompanied by nausea and vomiting. CT of the pelvis demonstrated a pathognomic ‘target’ sign, consistent with ileoceccal intussusception and early small bowel obstruction. Two years prior to this current presentation, the patient had experienced an episode of hematochezia for which he underwent colonoscopy and polypectomy, with subsequent pathology results negative for colon cancer. He denies diarrhea, constipation, weight loss, decreased appetite or skin flushing. Due to persistent symptoms of bowel obstruction, he underwent exploratory laparotomy. During the surgery a white-colored, chalky mass indicative of penetrating tumor was noted 13 cm proximal to the ileocecal valve. An extended right hemi-colectomy followed the discovery of the mass. Pathology showed a well-differentiated neuroendocrine tumor consistent with carcinoid tumor. Evaluation for metastatic disease using 5-HIAA and chromogranin A was unremarkable, and the resection of the right colon carcinoid tumor was felt to be curative. Conclusion: It is uncommon for adults to present with intussusception; in such cases, malignancy should be ruled out as an underlying cause. Carcinoid should be listed among the other secondary causes, which include inflammatory bowel disease, diverticulitis, polyps, scar tissue, adhesions, and lipomas.
