Multiple Primary Malignant Neoplasms in the Presence of Concomitant Chilaiditi Syndrome

Abstract

Chilaiditi syndrome, jejunal diverticulosis, and multiple primary malignant neoplasms (MPMN) are all relatively rare entities. In this study, clear cell renal cell carcinoma together with adenocarcinoma arising in the rectum were confirmed in an 82-year-old patient. Jejunal diverticulosis and Meckel diverticulitis were detected intraoperatively. Following radiotherapy with 25 Gy delivered in 5 fractions over 1 week, the patient underwent partial nephrectomy as well as abdominoperineal rectal resection and cholecystectomy due to cholelithiasis. The immediate postoperative period was uneventful, but the patient died of myocardial infarction on postoperative day 4. Malignancy may accompany Chilaiditi syndrome. In the presence of MPMN, appropriate treatment must be chosen individually on a case-to-case basis. Although there is no treatment for asymptomatic jejunal diverticulosis and Meckel diverticulitis, it should always be kept in mind that they may cause potentially serious complications.
