摘要

目的：

研究乳腺导管内原位癌（ductal carcinoma

in situ

，DCIS）的超声图像特点及病理学相关性，进一步提高其超声诊断水平。

方法：

回顾并分析108例乳腺DCIS的超声图像特征及病理相关性，将其分为结构紊乱团块型（Ⅰ型）、结节型（Ⅱ型）两大类，其病理学类型分为DCIS和导管内癌伴微浸润（DCIS with microinvasion，DCIS-MI）两类，病理学分级为低级别、中级别和高级别，全部经手术后病理学检查证实。

结果：

Ⅰ型59例，其声像图表现主要表现为中回声为主44例、最大径20 mm有35例、伴微钙化23例、边界不清晰59例、血流信号2级26例；Ⅱ型49例，其声像图主要表现为低回声为主39例、最大径＜20 mm有46例、边界不清晰39例、微小钙化8例、纵横比1有11例、血流信号＜2级43例。两组之间的回声强度、边界、大小、微小钙化、纵横比及血流分布差异有统计学意义（

＜0.05）。Ⅰ型结节中DCIS-MI中、高级别所占比分别为72.7%（24/33）和60.2%（53/88），两组病理学差异有统计学意义（

＜0.05）。

结论：

乳腺DCIS的超声表现多样，充分认识其超声图像特征及临床病理学特点，对正确诊断有一定帮助。

Abstract

Objective:

To investigate ultrasound imaging appearance of breast ductal carcinoma

in situ

(DCIS) and to correlate with pathological characteristics

to improve the diagnostic level of ultrasonography.

Methods:

Ultrasonographic images of 108 patients with breast DCIS confirmed by pathology were retrospectively reviewed

according to the ultrasonic images

it can be divided into two types

architectural distortion mass (t

ypeⅠ) and nodules (typeⅡ). There are two categories which are DCIS and DCIS-MI according to histological classification

and pathological grading for low-grade

middle-grade and high-grade. Ultrasound image types were compared with pathology.

Results:

TypeⅠin 59 cases

its ultrasonographic performance mainly for isoecho (44 cases)

major diameter 20 mm (35 cases)

with microcalcification (23 cases)

ill-defined border (59 cases)

blood flow grade 2 (26 cases). TypeⅡin 49 cases

its main performance for hypoecho (39 cases)

major diameter＜20 mm (46 cases)

ill-defined border (39 cases)

with microcalcification (8 cases)

ratio of anteroposterior and transverse diameters (A/T) 1 (11 cases)

blood flow ＜ grade 2 (34 cases). Significant difference between two type lesions in echogenicity

border

diameter

microcalcification

A/T and blood flow were found. There were 24 cases (72.7%) and 53 cases (60.2%) were DCIS-MI and middle-high grade in typeⅠrespectively

The difference of pathological classification in the two types was statistical significant (

＜0.05).

Conclusion:

The ultrasonographic findings of DCIS are varied

familiar with these ultrasonographic features and clinicopathological features is useful accurate diagnosis.
