Primary osteosarcoma of the uterus

Abstract

Post-menopausal vaginal bleeding is a common clinical problem. Often, the clinician will call upon the radiologist to perform and interpret studies such as ultrasound or computed tomography (CT), to aid in the diagnosis or to evaluate further a pelvic mass. The following case illustrates an unusual cause of postmenopausal vaginal bleeding, with ultrasound and CT images of the pelvic mass. Certainly, the radiologist, in interpreting scans and correlating them with clinical data, must always consider common etiologies first; but one ust also remember the uncommon and even rare entities that may radiologically mimic a more common pathologica process and, if appropriate, might be included in the differential diagnosis.
