Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
A Dieulafoy’s lesion is defined as a dilated submucosal vessel that erodes the overlying epithelium without evidence of a primary ulcer or erosion. It is a rare cause of gastrointestinal bleeding that is difficult to identify and subsequently manage. Most commonly, they occur in the upper gastrointestinal tract, namely the stomach. A Dieulafoy’s lesion of the rectum, however, is an exceedingly rare presentation that can lead to life-threatening gastrointestinal bleeding. Our case consists of an 84-year-old man, who presented with lower gastrointestinal bleeding secondary to a Dieulafoy’s lesion of the rectum.
