Vestibular schwannomas, meningiomas and epidermoids account for a vast
majority of the lesions occurring in the cerebellopontine angle (CPA). Neoplastic
and non-neoplastic pathologies other than these tumors constitute 1% of all
lesions located in the CPA. The aim of this study was to reveal our experience in
the treatment of the rare lesions of the CPA. We have retrospectively reviewed
the medical files and radiological data of all patients who underwent surgery
involving any kind of pathology in the CPA. We have excluded those patients
with a histopathological diagnosis of meningioma, schwannoma and
epidermoids. Our research revealed a case of craniopharyngioma, a case of
chloroma, a case of solitary fibrous tumor, a case of pinealoblastoma, a case of
atypical teratoid rhabdoid tumor, a case of an aneurysm, a case of hemorrhage
and a case of abscess.
