摘要

目的：

分析直径2 cm的小肝细胞癌（small hepatocellular carcinoma，sHCC）二维超声声像图及超声造影（contrast-enhanced ultrasound，CEUS）增强特征，以期评估CEUS诊断sHCC的应用价值。

方法：

回顾并分析2010年12月2019年12月上海市徐汇区大华医院经CEUS首诊并经穿刺或手术后病理学检查确诊的65例sHCC，对其病灶的大小、二维声像图特征及CEUS病灶直径为1.5~2.0 cm增强方式进行统计分析。

结果：

65例sHCC中，35例（53.85%）病灶直径＜1.5 cm，30例（46.15%）病灶直径为1.5~2.0 cm。二维图像表现形式有3种，低回声40例（61.54%），等回声14例（21.54%），高回声11例（16.92%），其中低回声为sHCC主要的表现形式。CEUS增强模式分为典型的快进快出型［34例（53.03%）］和不典型快进同出或慢出型［31例（46.97%）］，均出现在＜1.5 cm HCC中。对＜1.5 cm及1.5~2.0 cm的两组病灶的CEUS开始增强时间、消退时间及增强持续时间分析，消退时间和增强持续时间差异有统计学意义。

结论：

不同直径sHCC的CEUS增强消退时间、增强模式差异有统计学意义，CEUS有助于临床sHCC的早期诊断。

Abstract

Objective:

To explore the application value of contrast-enhanced ultrasound (CEUS) in the diagnosis of small hepatocellular carcinoma (sHCC) by retrospectively analyzing the characteristics of two-dimensional ultrasound and CEUS of sHCC with diameter 2 cm.

Methods:

Sixty-five cases of sHCC first diagnosed by CEUS and confirmed by surgical or puncture pathology in Dahua Hospital from December 2010 to December 2019

were retrospectively analyzed. The size of the lesions

two-dimensional sonograms and enhancement mode of CEUS were statistically analyzed.

Results:

Among the 65 cases of sHCC

35 cases (53.85%) had lesion diameter less than 1.5 cm

and 30 cases (46.15%) had lesion diameter between 1.5 and 2.0 cm. There were 3 types of two-dimensional image manifestations: 40 cases of hypoecho (61.54%)

14 cases of isoecho (21.54%)

11 cases of hyperecho (16.92%)

respectively. Hypoecho was the main manifestation of sHCC. CEUS enhancement pattern was classified into 2 types: 34 cases (53.03%) were the typical fast wash-in and wash-out type; 31 cases (46.97%) of atypical fast wash-in and the same or slow wash-out typei all appeared in ＜1.5 cm HCC. The beginning wash-in

wash-out time and duration of enhancement were analyzed for ＜1.5 cm and 1.5-2.0 cm lesions

and the time of wash-out and duration of enhancement were statistically significant.

Conclusion:

There are statistical differences in CEUS wash-out time and enhancement pattern in sHCC with different diameters

andCEUS is helpful in the diagnosis of sHCC in clinic.
