title: MR imaging findings and patterns of spread in secondary tumor involvement of the uterine body and cervix.
abstract: OBJECTIVE
  Our study sought to describe the MR imaging features and the patterns of spread in secondary tumor involvement of the uterus by nonuterine tumors.
  
  
  CONCLUSIONS
  Direct extension of an adjacent tumor to the uterus is the most common pattern of secondary tumor involvement. Concomitant invasion of other pelvic organs is also typical. Although less common, hematogenous or lymphatic metastases to the uterus are encountered in clinical practice. Metastases should be added to the differential diagnosis of apparently malignant masses in the uterine body or cervix, especially in patients with metastatic disease or in patients whose uterus shows a preserved shape with involvement by an infiltrative heterogeneously enhancing process.
