Giant sigmoid diverticulum: a case report.

OBJECTIVES

To report an unusual presentation of a giant sigmoid diverticulum in the colon.

CLINICAL PRESENTATION AND INTERVENTION: The patient presented with an abdominal mass, altered bowel habits, and increasing weight. The provisional diagnosis was made by barium enema and CT scan. The patient underwent laparotomy, revealing a perforated giant sigmoid diverticulum that was excised using Hartmann's procedure. The perforation could have been precipitated by the barium enema study. The histopathology of the resected specimen revealed giant sigmoid diverticulum with no evidence of malignancy.

CONCLUSION

CT scan was adequate for diagnosis of the suspected giant sigmoid diverticulum. Surgical intervention was successfully used to excise the diverticulum.
