CT scans are not the primary modality of assessing for underlying causes, but it may show some changes. It may be difficult to differentiate polyps, adenomyosis and leiomyoma’s from each other. CT can help asses for the presence of metastasis secondary to endometrial cancer.

CT Scan Findings

Underlying Cause	CT Scan	Findings
Endometrial Polyps[1]		Difficult to distinguish from adenomyosis
Adenomyosis[2]		Uterine enlargement may be seen Appear very similar to fibroids Adenomyosis is favoured if calcifications is present
Leiomyoma[3]		Soft tissue densities May exhibit coarse peripheral or central calcification May distort the smooth uterine contour
Malignancy[4]		CT is helpful in assessing for the presence of metastasis Difficult to differentiate from a normal uterus Thickening or a mass may be visible
