An unusual radiological presentation of mucinous adenocarcinoma of the colon

Abstract

Abstract:We report a case of an elderly patient presenting with the left iliac fossa mass. The provisional diagnosis included an infl ammatory diverticular mass or sigmoid colon cancer. Interestingly, computed tomography (CT) of the abdomen and pelvis demonstrated the left incarcerated Spigelian hernia containing an infl amed loop of the colon with signs of an early strangulation. However, at operation, a mucinous tumor was found involving the descending and upper sigmoid colon. The tumor eroded through the anterior abdominal wall, which was excised "en bloc." In the presented case, CT fi ndings suggestive of a benign etiology were misleading. This potentially could have had signifi cant consequences if the patient was treated conservatively.This case highlights that clinical history and examination remain the core components of a safe surgical practice. Clinical judgment cannot be substituted even by the best quality imaging.Therefore, we feel that it is important to share our experience of the successful management of the presented case.

Colonic mucinous adenocarcinoma causing intussusception and distant metastasis

“…Thus, these findings are not conducive to the early detection and treatment of MAC. [20,21] It has been reported that endoscopic ultrasound (EUS) has a unique advantage for the diagnosis of MAC associated with ascites; EUS frequently identifies ascites missed by other imaging studies, including abdominal CT. This study also demonstrated that EUS-guided paracentesis could identify malignancy in ascetic patients.…”
