Uncovering the Hidden Threat: Ileocolic Intussusception in an Adult With Appendicular Tumor.

Intussusception in adults is a rare condition, often associated with an underlying pathological lead point. This case report describes a case of intussusception in a 37-year-old female patient with an unusual lead point: an appendicular mucinous neoplasm. This case highlights the clinical presentation, diagnostic process, and management of adult intussusception caused by an appendicular neoplasm. The patient underwent a right hemicolectomy, with ileo-transverse anastomosis. The lead point was a low-grade appendiceal mucinous neoplasm (LAMN) without any intraoperative spillage. No signs of recurrence were seen till the last follow-up visit. Surgical intervention with appropriate resection of the lead point remains the treatment of choice, with histopathological analysis crucial for further management, in any adult intussusception.
