Sonographic and Multiplanar Computed Tomographic Findings of Large Uterine Perforation 2 Weeks After First-Trimester Pregnancy Termination

Abstract

Perforation of the uterus usually results from either iatrogenic or, less frequently, spontaneous occurrences. 1-6 Iatrogenic etiologies include perforations occurring during dilation and curettage, hysteroscopy, and insertion of intrauterine contraceptive devices or brachytherapy tandems or as a result of endometrial ablation. 1-3 Spontaneous etiologies include pyometra, gestational trophoblastic disease, placenta accreta, and rarely degeneration of a myoma and uterine infarction. 3-6 Procedure-related uterine perforation is usually considered and diagnosed clinically at the time of injury, hence the relative sparse literature pertaining to imaging findings associated with uterine perforation. We report an unusual case in which uterine perforation was confirmed by sonography and computed tomography 2 weeks after pregnancy termination at 13 weeks' gestation.
