Complications of routine fiberoptic colonoscopy are infrequent and consist mainly of perforation and hemorrhage (1). Other complications, seldom considered because they occur even more infrequently, must be kept in mind to make a timely diagnosis. Splenic injury is uncommon after colonoscopy but still should be considered in the differential diagnosis of post-colonoscopy abdominal pain. We found 13 reported cases in the English language literature (1-10). Our patient represents the 14th case. Computed tomography (CT) was important in the diagnosis (20-21).
