Dural Cavernous Haemangioma with Bony Infiltration

We report the findings in a 5-year-old boy with headache, intermittent vomiting and blurred vision who was found to have an enhancing, dural based extra-axial posterior fossa mass. This was proven histologically to be a dural cavernous haemangioma with bony infiltration. These uncommon lesions may closely resemble meningioma on computed tomography (CT), magnetic resonance imaging (MRI) and angiography in terms of location, enhancement, bony changes and signal characteristics [1,2]. To our knowledge this is the first report of a dural cavernous haemangioma with bony infiltration as seen on CT and only the second in the literature [3].
