Advanced imaging in evaluation of a central mandibular haemangioma.

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.
