摘要

目的：

探讨纵隔海绵状血管瘤(cavernous hemangioma of the mediastinum，CHM)的CT影像学特征，提高其诊断正确率。

方法：

回顾性分析经复旦大学附属肿瘤医院手术病理证实的11例CHM患者的CT影像学特征，分析CHM部位、大小及平扫和增强特征。

结果：

11例患者中，病灶位于前纵隔7例，后纵隔3例，1例同时累及中、后纵隔；且绝大多数位于上纵隔(10例)。病灶平均大小23 mm(10~69 mm)。8例病灶呈椭圆形或圆形，3例呈分叶状。2例见静脉石。7例呈轻度不均匀强化，3例中度不均匀强化，仅1例呈明显不均匀强化，其中9例患者瘤内见结节样强化灶。2例可见瘤内畸形静脉显示。

结论：

CHM好发于上纵隔，前纵隔多见，静脉石、病灶内结节样强化灶及瘤内畸形静脉显影为其CT特征性表现，增强CT有助于CHM的诊断。

Abstract

Objective:

To investigate the CT imaging features of cavernous hemangioma of the mediastinum (CHM) and to improve its diagnosis accuracy.

Methods:

The CT imaging features of 11 patients with CHM were analyzed retrospectively.

Results:

The location of 11 cases with CHM was as following: 7 cases were in the anterior mediastinum

3 cases in the posterior

and 1 case involved both middle and posterior mediastinum; Most were in the upper mediastinum (10 cases). The average size was 23 mm (range 10-69 mm). Eight cases were oval-shaped or round

3 cases lobulated. Phlebolith was identified in 2 cases. After contrast-enhanced CT scan

mild inhomogeneous enhancement was found in 7 cases

moderate inhomogeneous enhancement in 4 case

significant inhomogeneous enhancement only in 1 case. The nodular enhancement was identified in 9 cases. Aberrant veins originating from the left brachiocephalic vein and superior vena cava were found in 2 cases.

Conclusion:

CHM involved the anterior mediastinum is more frequent than the posterior mediastinum

and most are in the upper mediastinum. Phlebolith

the nodular enhancement

and aberrant veins in the lesion are the characteristic CT findings. Contrast-enhanced CT scan is helpful for the diagnosis of CHM.
