We present a case of histologically-verified central cavernous haemangioma. The conventional radiological films as well as the computed tomographic (CT) and magnetic resonance imaging (MRI) features of this lesion are described. Plain films showed many of the typical radiological signs of haemangioma, whereas CT was primarily useful for illustrating the bony components of the tumour as well as delineating soft tissue extensions and bony defects not normally visible with plain film examination. MRI proved particularly useful, demonstrating the vascular nature and flow voids representative of feeder vessels and delineating the true extent of the lesion. The literature pertaining to the imaging features of central haemangioma is reviewed and the complementary use of plain films, CT and MRI described. To our knowledge, this is the first report detailing the MRI characteristics of a central mandibular haemangioma.
我们报告一例经组织学证实的中央海绵状血管瘤病例。描述了该病变的传统放射学影像以及计算机断层扫描（CT）和磁共振成像（MRI）特征。平片显示出许多典型的血管瘤放射学征象，而CT主要用于显示肿瘤的骨质成分以及勾勒平片检查通常无法看到的软组织延伸和骨质缺损。MRI被证明特别有用，它能显示代表供血血管的血管性质和血流空洞，并勾勒出病变的真实范围。对有关中央血管瘤影像特征的文献进行了综述，并描述了平片、CT和MRI的互补应用。据我们所知，这是第一份详细描述下颌骨中央血管瘤MRI特征的报告。
