Case Report

An 18-year-old woman presented with crampy upper abdominal pain for 16 months. An esophagogastroduodenoscopy 1 year prior was notable only for heterotopic pancreatic tissue in the gastric antrum. Past history included asthma and congenital genitourinary and pelvic malformations with multiple urological surgeries and genitoplasty. Abdominal examination showed scars from previous surgeries but was otherwise normal. An abdominal and pelvic computed tomography showed left-sided hydroureteronephrosis, partial duplication of the urinary bladder, and duplication of uterus and cervix. A colonoscopy showed no evidence of macroscopic colitis. Surprisingly, 2 cecae were noted, each with its own appendicial orifice. The terminal ileum had a normal appearance and was intubated via a triangular valve between the 2 cecae (Figure 1). Biopsies from colon and terminal ileum were normal.

Duplications of the gastrointestinal tract are rare and have a reported incidence of 1 in 5,000 live births.1 Only about 17% of these are located in the colon and rectum, with an incidence of 0.004%.2 Duplications of the appendix can be classified by the Cave-Wallbridge classification. In type A, there is partial duplication, and both the appendices have a common base. In type B, a single cecum has 2 completely separate appendices. Type C is a double cecum, each with its own appendix, as in this case. Most of these are also associated with other hindgut duplications.3,4 This case had no other associated gastrointestinal duplications, and both cecae communicated with the terminal ileum and ascending colon, increasing the rarity of the report.
