摘要

目的：

通过对胃贲门平滑肌瘤的CT影像学特征进行分析，提高对胃贲门平滑肌瘤的诊断水平。

方法：

回顾性分析经手术切除并经病理证实的16例贲门平滑肌瘤患者的CT影像学特征。所有患者行CT平扫及动脉、门静脉双期增强扫描。

结果：

16例贲门平滑肌瘤的CT表现为边界清楚的软组织肿块；有腔内生长（

=7）、腔内外跨壁生长（

=6）及腔外生长（

=3）3种生长方式；呈不规则形（

=6）、类圆形（

=5）、扁平形（

=3）及分叶状（

=2）4种形态。三期动态CT扫描中，肿瘤的CT均值分别为42.3 HU（平扫）、49.0HU（动脉期）和56.6 HU（门静脉期），门静脉期表现为轻度强化（

=3）和中度强化（

=13）。肿瘤伴发溃疡及胃周淋巴结肿大各有6例。

结论：

CT多平面重建有利于胃贲门平滑肌瘤形态多样性的显示，结合CT强化特征有助于术前诊断。

Abstract

Objective:

To analyze the CT features of leiomyoma of gastric cardiac

and to improve the diagnostic level.

Methods:

The CT features of 16 patients with pathology-proven leiomyomas of gastric cardia were retrospectively reviewed. All 16 patients underwent non-enhanced and contrast-enhanced CT in arterial phase and portal phase.

Results:

The leiomyomas showed well-defined solid masses

with endoluminal (

=7)

mixed (

=6) or extraluminal (

=3) growth patterns. There were 4 contours: irregular (

=6)

circular (

=5)

lattened (

=3) or lobulated (

=2). The mean CT values were 42.3 HU (plain scan)

49.0 HU (arterial phase)

and 56.6 HU (portal phase)

respectively. In portal phase

mild enhancement was found in 3 cases and moderate enhancement in 13 cases. Six cases had ulceration and 6 cases had perigastric lymph node enlargement.

Conclusion:

CT multi-planar reconstruction which is beneficial to reveal the diverse contour of leiomyoma of gastric cardiac

combined with CT enhanced features is helpful for preoperative diagnosis.
