ABSTRACT
OBJECTIVE:
To report a case of VIIIth nerve cavernous hemangioma, a very rare differential diagnosis among the various pathologies presenting as small enhancing entities into the internal auditory canal. It is one of the most challenging when imaging is not able to differentiate it from an intrameatal vestibular schwannoma. METHODS ANDRESULTS:
We report a cavernous hemangioma extruding from the internal auditory canal, diagnosed after a left translabyrinthine resection in a 45-year-old man complaining of profound sensorineural hearing loss, with no facial paresis or dizziness. The preoperative differential diagnosis of a vestibular schwannoma was impossible, due to the absence of calcifications that usually characterize temporal bone hemangiomas. Clinical presentation, radiological features and treatment considerations are discussed along with up-to-date review of pertinent literature.CONCLUSIONS:
When considering an apparent small intra-auditory canal schwannoma, otoneurologists should be aware of the rare possibility of a cavernous hemangioma. Early diagnosis and surgical treatment may improve the functional outcome, possibly preserving neural integrity.Palavras-chave
