胃肠平滑肌类肿瘤声像图表现及其评价

Differential Diagnosis of Ultrasonography in Gastroenteric Liomyoma and Liomyosarcoma

本文报告28例胃肠平滑肌瘤采用饮水和灌水充盈法超声诊断,所有病例均经手术病理证实。超声定位符合率85.7%(24/28),定性诊断符合率82.1%(23/28),误诊率为17.9%(5/28)。根据肿瘤的生长方式、形态学特征,结合病理所见,提出声像图分为三型:腔内型(局限隆起型)、腔外型(外生型)、混合型(哑铃型)。文中重点讨论了声像图表现及其鉴别,客观评价了超声诊断价值。指出超声与X线、内镜检查资料相结合,有助于提高本病诊断正确率。

This article reported 98 cases of gastroenteric liomyoma and liomyosarcoma diagnosed by ultrasonography, All of them have been confirmed by operation and pathology. The accuracy of sonographic diagnosis in position was 85.7%(24/28), in cause was 82.1%(23/28) and the misdiagnostic rate was 17.9%(5/28). According to growth pattern and morphologic character of tumor combining with pathology, ultrasonography of the diseases might be classified in three categories: intraluminal, extraluminal and mixed types. The ultrasonographic manifestation and the distinguishing diagnosis of the diseases are mainly and it's diagnostic value are objectively assessed. The authors suggested that B—mode ultrasonography with X—ray and endoscopy be likely to raise correct rate of diagnosis of the gastroenteric liomyoma and liomyosarcoma.
