目的 探讨灰阶及彩色多普勒超声对肝脏囊性恶性肿瘤的临床诊断价值。方法 分析了 16例肝脏囊性恶性肿瘤的灰阶及彩色多普勒特征。其中肝脏原发肿瘤 8例 ,转移性肝肿瘤 8例。灰阶超声观察肿瘤的大小、形态、数目、囊壁的厚度及内部回声 ,多普勒超声观察肿瘤的供血状况并测定其流速。结果 原发肿瘤以单发病灶多见 ,转移性肿瘤以多发病灶多见。肿瘤直径为 1.9～ 13.6cm。 8例呈类圆形 ,5例为不规则形 ,3例呈分叶状。 15例表现为囊壁不规则增厚 ,7例内有厚分隔 ,6例可见向囊腔内突起的乳头样结节。彩色多普勒显示 14例于壁内、乳头结节内或分隔上引出血流信号 ,其中 13例为搏动性血流信号。结论 肝脏囊性恶性肿瘤的灰阶超声表现为厚壁不规则的囊性病变 ,彩色多普勒能够较好地反映其囊壁、分隔及乳头内的血流信号 ,为肝脏囊性恶性肿瘤的诊断提供了重要依据。
Objective To investigate the value of gray scale and color Doppler ultrasound in the diagnosis of hepatic cystic malignancies. Methods The gray scale and color Doppler features of 16 cases of malignant cystic liver tumors were analyzed. Including liver primary tumor in 8 cases, 8 cases of metastatic liver tumor. Tumor size, morphology, number, wall thickness and internal echo were observed by gray-scale sonography. The tumor blood supply was observed by Doppler ultrasound and the flow rate was measured. Results Primary tumors were more common in single lesions and metastatic tumors were more common in multiple lesions. Tumor diameter of 1.9 ~ 13.6cm. 8 cases were round, 5 cases of irregular shape, lobulated in 3 cases. 15 cases showed irregular thickening of the wall, thick separation in 7 cases, 6 cases visible to the cysts protruding papillary nodules. Color Doppler showed 14 cases in the wall, the nipple nodules or leads to the separation of blood flow signals, of which 13 cases of pulsatile blood flow signal. Conclusions The gray scale ultrasound of liver cystic malignant tumors is irregular thick cystic lesions. Color Doppler can better reflect the cyst wall, septal and papillary blood flow signals, Diagnosis provides an important basis.
