[Lipoma of the cerebellopontine angle: two cases report and review of literature].
Here we report two cases with cerebellopontine angle lipoma. Cerebellopontine angle lipomas previously reported in the literature were reviewed. The review of the literature revealed the condition is more prevalent in women. The median tumor size was 10.26 (range: 1 to 26) mm. It was noted that these tumors are most frequently associated with hearing loss (56%) and tinnitus (40%), while 9% demonstrate no symptoms. Fifty-six percent of these patients had been operated, however complete resection had been accomplished in only 36% of patients. In our cases, the tumor sizes were 7 x 4 and 5 x 3 mm. Tinnitus and ear fullness were major complaints in both cases. One case had hearing loss and vertigo in addition to these complaints. Surgery was not performed for these cases. The patients have been followed up using same approach without any complication. Histopathological diagnosis is rarely necessary with the widespread use of magnetic resonance imaging. Because of the potential for significant morbidity with resection of these lesions, conservative follow-up is the best approach for cerebellopontine angle lipoma.
