Sonographic and magnetic resonance imaging findings of pelvic abscess following uterine perforation sustained during office endometrial sampling.

Pipelle endometrial sampling, an outpatient, office-based procedure, provides comparative successful endometrial sampling in comparison with other techniques including conventional dilatation and curettage. We present an unusual occurrence in which office Pipelle endometrial sampling in a perimenopausal patient was complicated 10 days later by lower abdominal pain and intermittent fever. Sonography depicted findings consistent with a large pelvic abscess overriding the uterine fundus. Sonography and magnetic resonance imaging confirmed the presence of the unusual pelvic abscess and, in addition, noted findings consistent with perforation of the uterus during endometrial sampling.
