摘要/Abstract

摘要： 目的：探讨口腔颌面部高血循肌间血管瘤（IMH）的CT、MRI（包括磁共振动态增强）的表现特征与病理分型的关系。方法：回顾分析2001—2013年间18例经病理检查证实的口腔颌面部IMH患者的术前影像学资料。其中男3例，女15例，年龄5~57岁，平均年龄33.4岁。结果：CT、MR图像显示，6例患者累及多块肌肉，12例累及单块肌肉。好发于咬肌（6例）及舌体（6例）。3例患者影像学表现为高血循病变，磁共振动态增强的SI-time曲线为Ⅱ型：早期快速强化后出现平台期，病理分型为毛细血管型2例、混合型1例。15例患者影像学表现为低血循病变，SI-time曲线为Ⅰ型，病理分型为海绵血管型。4例发现静脉石。结论：IMH的 CT、MR影像学表现及其SI-time曲线分型，能进一步帮助诊断其病理分型。

Abstract: PURPOSE :The aim of this study was to investigate CT and MR imaging findings of intramuscular haemangiomas(IHM) in oral and maxillofacial region and correlate them with the histopathological classifications. METHODS : Eighteen IHM in oral and maxillofacial region were treated from 2001 to 2013 in our hospital. All of them had CT and/or MRI scans before surgical procedures. Six patients had CT and 17 had MRI scans. Three were males and 15 were females, their age ranged from 5 to 57 years with a mean age of 33.4 years. RESULTS : CT and MRI showed that 6 patients had multi-muscular and 12 had single-muscular lesions. Predilection sites were masseter muscle (6 cases) and tongue (6 cases). Three cases had high-flow lesions on CT and MR images with type Ⅱ time-signal intensity curve (SI-time curve). They were classified histologically as capillary or mixed type. Fifteen cases had low-flow lesions with type Ⅰ SI-time curve, classified as cavernous type. Among them, four had phleboliths. CONCLUSIONS : Histological classifications of IHM can be determined based on CT and MR imaging findings and the types of SI-time curves.
