HSG with Catheter Balloon Filled Inside Uterus
Radiograph of a hysterosalpingogram revealing a large rounded filling defect within the uterine cavity. This filling defect is due to inflation of the injection catheter’s balloon (intended to keep the catheter from falling out of the uterus during the examination), making visualization of most of the uterine cavity impossible. Many hysterosalpingogram films that I have reviewed from outside institutions do not have an early film of the uterine cavity without the presence of an inflated balloon, making identification of a (subtle) defect in the uterine cavity very unlikely. Additionally, there is no orientation marker on this radiograph.
