We report a case of a 40-year-old female who presented with colonic intussusception and obstruction caused by an ovarian teratoma invading a segment of the colon. Contrast-enhanced CT imaging revealed a soft tissue mass within the colon, and colonoscopy identified a large cystic lesion approximately 6.0 \u00d7 6.0 cm in size located 20 cm from the anal verge. This lesion obstructed the lumen, causing significant narrowing. Preoperatively, the condition was misdiagnosed as intussusception caused by a colonic diverticulum. During laparoscopic exploration, a left ovarian tumor invading the colon was identified as the cause of the intussusception and obstruction. Consequently, partial colectomy and left oophorectomy were performed. Histopathological examination confirmed the diagnosis of a mature ovarian teratoma. The postoperative recovery was uneventful, and the patient was discharged in good health. This case report presents a rare instance of intussusception, highlighting the challenges associated with achieving an accurate preoperative diagnosis. Surgical intervention remains the primary treatment modality for patients with this condition.<\/jats:p>","DOI":"10.3389\/fonc.2025.1555443","type":"journal-article","created":{"date-parts":[[2025,5,1]],"date-time":"2025-05-01T04:14:44Z","timestamp":1746072884000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Ovarian
