Cavernous haemangioma of the facial nerve.

Facial nerve haemangiomas are probably the most frequent benign tumours involving the facial nerve in its intratemporal portion. Usually facial nerve dysfunction is present when these tumours are of extremely small size, the average tumour being less than 10 mm. We present a case of a 15 mm diameter cavernous haemangioma of the geniculate region, with histological findings of nerve infiltration, without facial nerve symptoms. The atypical clinical presentation justifies the report and subsequent literature review.
