Inadvertently performed hysterosalpingography during early pregnancy.

A review of 6,225 hysterosalpingographies disclosed four cases of inadvertently performed examinations during early pregnancy. These radiologic misadventures were in three cases performed because of oligomenorrhoea and in one case because of a misjudged decidual bleeding. The radiologic findings and the outcome of these pregnancies are presented. Precautions to avoid this radiographic error are discussed.
