intra-uterine air

The presence of intrauterine gas (a.k.a. pneumouterus) can sometimes be inferred by tiny internal echoes on ultrasound, foci of very low attenuation at computed tomography (CT) or signal voids with susceptibility artifact at MRI. The term encompasses air within the uterine cavity as well as intramyometrial air.

It can arise from a number of situations:

• normal postpartum period : it may be seen in ~ up to 20% of healthy patients in the postpartum period
• pelvic inflammatory disease/endometritis
• post intrauterine instrumentation
• abnormal fistulous connection with the gastrointestinal tract
