Endometritis refers to inflammation or infection involving the endometrium. Endometritis can be acute or chronic and may arise in an obstetric setting, such as following delivery or miscarriage, or in a non-obstetric setting due to pelvic inflammatory disease (PID) or endometrial instrumentation.

It complicates 2-3% of vaginal deliveries as well as up to 85% of Cesarean sections 5.

Endometritis is the most common cause of fever in a postpartum patient 6.

The typical presentation is with fever and lower abdominal pain. While imaging features can be helpful, the diagnosis is clinical as imaging can be normal, particularly in uncomplicated cases.

Endometritis is a clinical diagnosis and caution should be taken due to the overlap of expected postpartum imaging findings and the ones related to the inflammatory process.

While the sonographic appearance of the uterus and endometrium may be normal in early stages, findings may include:

  • thickened and heterogeneous endometrium
  • intracavitary/cul-de-sac fluid
  • increased vascularity on Doppler ultrasound
  • intrauterine air
  • T2: the uterus may be enlarged with overall high signal intensity
  • T1 C+ (Gd): can show intense enhancement of the uterus
