Appendiceal Intussusception Induced by Cecal Adenocarcinoma in Tubular Adenoma: A Case Report

盲腸腺癌導致闌尾套疊:病例報告

摘要


闌尾套疊是很少見的闌尾病理變化。我們報告了一位58歲男性因解十天黑便及頭暈、全身無力來院治療,影像學檢查發現盲腸部瘜肉,但瘜肉底部發現疑似被捲入之腸繫膜及血管。雖大腸鏡切片呈現良性組織,後經手術切除時卻發現闌尾套疊,病理報告證實為盲腸腺癌導致。文中將描述新發現之影像學表現並作相關文獻的回顧。

Intussusception of the appendix is rare in worldwide studies and is difficult to recognize before operation. We report a case of a 58-year-old, previous healthy male with defecating tarry stool for 10 days with dizziness, general weakness. Double contrast colon series and abdominal computed tomography (CT) revealed a 2.5 cm pedunculated, polyp-like lesion adjacent to the ileocecal region, and the appendix was not found. The pathological findings of biopsy tissues of colonoscopy only showed inflammatory change. Appendiceal intussusception was finally recognized during the operation. The pathological report of the specimen from right hemicolectomy revealed a cecal adenocarcinoma in tubular adenoma. Appendiceal intussusception is an interesting variation of the appendiceal diseases that the colonoscopist, radiologist, and general surgeon must know and better to identify before operation to avoid possible perforation during biopsy.
