TY - JOUR T1 - A puzzling case presenting as a polypoid mass in the cecum in an adult patient: appendiceal intussusception TT - Erişkin bir hastada çekumda polipoid kitle olarak prezente olan şaşırtıcı bir olgu: apendiks intussusepsiyonu AU - Çomut, Erdem AU - Karabaş, Hande AU - Ozgen, Utku AU - Özban, Murat AU - Demirkan, Neşe PY - 2023 DA - July Y2 - 2023 DO - 10.31362/patd.1269591 JF - Pamukkale Medical Journal JO - Pam Tıp Derg PB - Pamukkale Üniversitesi WT - DergiPark SN - 1308-0865 SP - 516 EP - 521 VL - 16 IS - 3 LA - en AB - Appendiceal intussusception is a rare condition in an adult patient and may not be initially considered in the differential diagnosis clinically or radiologically. It occurs due to an organic cause or idiopathically. We report a 74-year-old patient who had a polypoid lesion in the cecum on colonoscopy with no radiologic imaging and was ultimately diagnosed grossly and histopathologically as appendiceal intussusception. In conclusion, physicians are advised to consider appendiceal intussusception as an alternative diagnosis in all patients presenting with a suspected cecal mass. KW - Appendix vermiformis KW - intussusception KW - cecum KW - inverted appendix N2 - Apendiks intussusepsiyonu yetişkin bir hastada nadir görülen bir durumdur ve başlangıçta klinik veya radyolojik olarak ayırıcı tanıda düşünülmeyebilir. Organik bir nedene bağlı olarak veya idiyopatik olarak ortaya çıkar. Bu yazıda, kolonoskopide çekumda polipoid lezyon saptanan ve radyolojik görüntüleme yapılmayan, sonuçta gross ve histopatolojik olarak apendiks intussusepsiyonu tanısı konulan 74 yaşında bir hasta sunulmuştur. Sonuç olarak, hekimlere çekumda kitle şüphesi ile başvuran tüm hastalarda apendiks intussusepsiyonunu alternatif bir tanı olarak düşünmeleri önerilmektedir. CR - 1.
