Abstract
The traditional understanding of Meckel's diverticulum has always emphasized its antimesenteric location, ever since its original description in 1809. We report the finding of an acutely inflamed mass located on the mesenteric aspect of distal ileum, which was discovered during a celiotomy performed aboard a U.S. Navy aircraft carrier. Pathological features of this unusual mass, including focal submucosal abscess formation, proximity to the ileocecal valve, and heterotopic gastric tissue are all characteristic of inflammatory Meckel's diverticulum. The atypical intraoperative finding of a desmoplastic reaction associated with this lesion is discussed within the context of a pertinent differential diagnosis. In addition, both the pathological characteristics and the unusual location of this mass are the basis for a discussion that revisits a 50-year-old surgical controversy regarding Meckel's diverticulum.
