摘要

目的：

探讨并总结阑尾低级别黏液性肿瘤（low-grade appendiceal mucinous neoplasm，LAMN）的超声及CT图像特征。

方法：

回顾性分析经手术后病理学检查证实的12例LAMN的超声及CT图像，归纳其特征，包括肿瘤位置、大小、形态、边界、内部结构、血供情况及与周围组织的关系等。

结果：

12例LAMN的超声表现可分3型：盲管状型2例（16.7%），囊性为主包块型7例（58.3%）及实性为主包块型3例（25%）；CT表现则分为2型：囊性包块型9例（75%）及不规则包块型3例（25%）。

结论：

LAMN的超声和CT图像表现具有一定特征性，加强其超声及CT图像特点的认识，对减少误诊、漏诊具有重要临床意义。

Abstract

Objective:

To investigate and summarize the ultrasonic and CT manifestations of low-grade appendiceal mucinous neoplasm (LAMN).

Methods:

The ultrasonic and CT images of 12 LAMN cases confirmed by surgery and pathology were retrospectively analyzed

and the characteristics including tumor location

size

shape

border

internal structure

blood supply and relationship with the surrounding tissues were summarized.

Results:

Ultrasonic images were divided into three types: blind tubular type in 2 cases (16.7%)

mainly cystic mass type in 7 cases (58.3%)

and mainly solid mass type in 3 cases (25%). While CT images were divided into two types: cyst

ic mass type in 9 cases (75%) and irregular mass type in 3 cases (25%).

Conclusions:

Ultrasonic and CT manifestations of LAMN have certain characteristics. Full understanding of the ultrasonic and CT manifestations of this disease could reduce misdiagnosis and missed diagnosis.
