Radiographic manifestations of malignant mixed uterine tumors

Malignant mixed uterine tumors have a varied radiographic appearance. The primary tumor is usually evident as an enlarged uterus, frequently with localized, faint, punctate calcification. New or increasing calcification within an enlarging uterus of a postmenopausal female should raise the suspicion of mixed malignant uterine tumor. Metastases are common, and usually involve the lung, most often becoming apparent quite rapidly. The pattern of pulmonary metastases is varied from large masses to lymphangitic spread, hilar lymph nodes and pleural effusions being common. Calcification within pulmonary secondaries may occur and cavitation has been observed.
