[Atypical ossifying hemangioma of the temporal bone]

Over the last decade, the hemangioma of the temporal bone has become clinically recognized as the benign tumor most commonly involving the facial nerve in its intratemporal portion. Its locally aggressive nature affects the VIIth cranial nerve at a very early stage, usually before the tumor reaches a 10 mm diameter. We present a case of ossifying hemangioma of the temporal bone which, in spite of being located in the region of the geniculate ganglion and of measuring over 20 mm, only caused hearing conductive loss. The atypical clinical course of this case contrasts with those described in the literature.
