Introduction:
We report a rare case of abdominal wall abscess caused by ileal diverticulitis that developed along the midline below the umbilicus and resembled a urachal carcinoma.
Case Presentation:
A 76-year-old woman with diabetes presented with abdominal enlargement below the umbilicus. Computed tomography revealed a well-enhanced mass, which was visualized on magnetic resonance imaging as a continuous mass connected to the restiform structure, extending from the umbilicus to the bladder. As the mass showed high uptake on 18F-fluorodeoxyglucose positron emission tomography, urachal carcinoma was suspected, and surgery was subsequently performed. As the tumor adhered to the ileum, partial resection of the small intestine was required. The pathological diagnosis was abdominal wall abscess associated with ileal pseudodiverticulitis.
Conclusion:
Although abdominal wall abscess caused by ileal diverticulitis is rare, it should be considered as a differential diagnosis of urachal carcinoma.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
