Intrauterine pregnancy confirmed but not interrogated in detail. The appendix is not clearly identified. However, there are no signs of acute appendicitis with no oedema or free fluid near the caecal pole, and no focus of abnormal restriction diffusion. 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.
