Eliezer M, Tran H, Inagaki A, et al. - Because metastatic lesions of internal auditory meatus (IAM) and/or the cerebellopontine angle (CPA) were uncommon and can appear as vestibular schwannoma, researchers reported malignant CPA lesions, their diagnosis and treatment, reviewed the literature, suggested suspicion criteria for malignant CPA tumors. They included 9 patients who had malignant lesions of the CPA and/or IAM for whom the final diagnosis was made by surgery, lumbar puncture, or PET scan. According to results, rapid tumor growth was observed at a mean time interval of 4.6 months in 77% of cases. An atypical aspect of the MRI was observed in 67% of the cases with bilateral tumors in 55% of cases. Although rare, malignant CPA and/or IAM tumors should be evoked when cochleovestibular symptoms and facial palsy are associated, rapid onset and atypical aspect of MRI should occur.
