Presentation
Chronic pelvic pain.
Patient Data
Subseptate uterus. The intrauterine contraceptive device (IUCD) is located outside of the uterine cavity in the Douglas pouch adjacent to the rectal wall with mild surrounding fat stranding and minimal effusion. No adjacent intraluminal gas. No signs of acute uterine perforation.
Partial septum involving the upper uterine canal, not extending to the cervix (common cervix) with mildly concave surface of the fundus, and acute angle between the uterine cavities (46° in this case).
Case Discussion
CT features of a peritoneal migration in the Douglas pouch of an IUCD inserted 2 years ago in a patient with a subseptate uterus with no signs of acute uterine or rectal perforation.
CT is the modality of choice to detect the complications that could be due to the migration of an IUD such as hollow visceral perforation, abscess formation, pelvic inflammatory disease.
