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. There is restricted diffusion. The appearances are consistent with acute appendicitis. The right ovary, containing a small peripheral cyst, is located very close to the inflammatory appendix mass.
Incidental note is made of right-sided physiologic hydronephrosis caused by compression of the ureter between the uterus and the right psoas muscle, and distension of the right ovarian vein.
