Abstract
- Intracranial lipomas located in the cerebellopontine angle are extremely rare. These tumors are maldevelopmental lesions which can cause slowly progessive neurological symptoms. The clinical management of these tumours differs significantly from other lesions in this region. A 45 year old man presented with a 3-month history of vertigo and tinnitus in the left ear. In T1-weighted magnetic resonance imaging, the lesion was hyperintense and did not enhance after application of gadolinium. The patient was treated with medical therapy with good response. We present a review of the literature, with particular regard to management. Conservative treatment is recommended and limited surgery is usually indicated if the patients suffer from disabling neurological symptoms and signs e.g., vertigo, nausea, trigeminal neuralgia, facial weakness or facial spasm.
