| Objective-- Leiomyosarcoma is one of the three most common histological variants of uterine sarcoma. A high index of suspicion is needed in the diagnosis of this rare but highly fatal tumor. The aim of this retrospective study was to discuss the misdiagnosis of sonography in distinguishing LM from LMS, and to describe the rare sonographic features of LMS.
Materials and Methods-- All patients had undergone transvaginal and or transabdominal ultrasound examination before histopathological examination. We analyzed the preoperative gray-scale and color Doppler sonographic findings of 2 patients. Number, size, echotexture, degenerative changes, and vascularity (central or peripheral; absent, mild, moderate, or marked) were recorded. All patients underwent laparotomy. Results--They were found to have uterine malignancies and these were confirmed to be leiomyosarcoma after pathologic examination. About our 2 cases, one without degenerative cystic changes and the other with calcification which were not consistent with a majority of LMSs sonography. In addition, the vascularity showed in the whole mass had not a marked increase. Conclusions-The findings of the present study suggest that when uncharacteristic sonography of LMSs were observed, more effort should be directed at ruling out uterine sarcoma in all patients with presumptive diagnosis of leiomyoma, more especially if they are postmenopausal. |
