@entity3 of the inner auditory canal is a really rare event. Clinically, it usually presents with rapid worsening @entity129 . Authors present a review of the literature reporting clinical features, radiological findings, intraoperative aspects of an illustrative case. A 56-year-old female @entity1 presented with a peripheral @entity2103 . MRI showed two left p-fossa @entity5 whose one into the inner canal. Rapid worsening of @entity16 despite corticosteroid treatment and the possibility to remove both @entity5 in the same surgical step suggested authors to operated on the @entity1 . Intraoperatively, inner canal @entity5 looked totally involving the VII-VIII nerve complex so surgical extirpation was only partially feasible. Posterior wall drilling of the meatus was performed which improved @entity3541 . Leptomeningeal spinal seeding occurred and spinal irradiation was performed. The case highlights the importance of maintaining a high degree of awareness of the auditory canal @entity3 in @entity1 with a previous history of @entity5 who develop a rapid progressive @entity1897 . Furthermore, our case and literature data suggest that inner canal @entity3 is a distinct entity from temporal bone and ponto-cerebellar angle @entity3 on the base of the peculiarity of clinical features, prognosis, therapeutic strategies. In fact, inner canal metastases usually arise in @entity1 apparently cured, and they imply a better prognosis even if with an higher risk of leptomeningeal seeding. Moreover, surgery rarely allows the @entity75 , also if symptoms relief may be achieved, as in our case.
