Intrauterine pregnancy confirmed but not interrogated in detail. The gravid uterus displaces the cecal pole and appendix out of the right iliac fossa. An acute inflammatory mass is present adjacent to the cecal pole, medially and posteriorly, with edema of the fat and a small volume of free fluid. Appendicoliths are seen within the distended edematous appendix, with a small fluid collection immediately adjacent. Appearances consistent with acute appendicitis with localized perforation and fluid collection. Incidental note is made of distension of the right ovarian vein.
