Objective: Appendiceal cystadenoma (AC) is a rare pathology diagnosed in 0.6% of all appendectomy operations. The purpose of the report was to present a rare case of ileal volvulus due to appendiceal cystadenoma, which was successfully treated with surgery.
Case: A woman aged 76 years was admitted to our emergency service with severe right lower quadrant pain. Abdominal tomography and X-ray showed features of generalized dilatation of bowel segments with periluminal fluid collections. Intraoperatively, we found bowel volvulus and a 2 cm mass at the appendiceal borders and an appendectomy was performed. The volvulated ileal segment was resected and restored with end-to-end anastomosis. Histopathologic examination of the mass revealed mucinous cystadenoma. Our patient was discharged from hospital at postoperative one week with complete clinical recovery.
Conclusion: Obstruction of the appendiceal lumen by a mucinous neoplasia can cause appendicitis followed by secondary volvulus in different parts of the gastrointestinal tract. Our case was further complicated by ileal volvulus, which led to an extremely rare presentation.
