The cause of a uterine filling defect may be due to polyps, tumors, or adhesions in the uterine cavity.
A uterine filling defect is a description on radiologic imaging reports of a space-occupying lesion in the uterine cavity, which is caused by the inability of the contrast to fill after an examination with contrast media.
The cause of a filling defect in the uterine cavity is usually associated with polyps and tumors, such as endometrial polyps, endometrial cancer, fibroids, cervical cancer, and other diseases. The nature of the lesion can usually be determined based on the shape of the contrast vacancy. If the shape is relatively regular and the edges are smooth, most of the lesions are benign. If the shape is irregular and the edges are not clear, malignant lesions are mostly considered.
If filling defects are detected during hysterography, other relevant examinations should be further improved, and if necessary, targeted treatment should be carried out in accordance with the doctor’s instructions.
