Abstract
Aims: To present an unusual case and our therapeutic approach about a clinical case of ileocecal intussusception caused by appendiceal mucinous neoplasm.
Presentation of Case: A 54-year-old female patient came to the emergency department with abdominal pain. Complementary diagnostic exams showed an image of ileocolic invagination due to an appendicular mass, confirmed intraoperatively. A right hemicolectomy was performed for oncological purposes. The anatomopathological study revealed a low-grade appendicular mucinous neoplasm.
Discussion and Conclusion: Ileocecal intussusception is a rare diagnosis in adults, 80-92% of cases are secondary to an underlying pathology, usually identified intraoperatively. The treatment is surgical, due to the high incidence of a malignant etiology. In this particular case, there was already a preoperative suspicion of an appendicular neoplasm, which justified proposing a right hemicolectomy. There is no general consensus on the post-operative monitoring of Low-Grade Appendiceal Mucinous Neoplasm (LAMN). In this case, the follow up was an analytical study with tumor markers, computed tomography and colonoscopy. After 5 years, the patient was asymptomatic, with no signs of recurrence.
