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.
