Rare lesions of the cerebellopontine angle

Rare lesions of the cerebellopontine angle.

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 med...

Metastatic lesions involving the cerebellopontine angle.

PURPOSE To evaluate the clinical and MR findings of metastatic lesions involving the cerebellopontine angle (CPA), which may be useful in differentiating them from the more commonly occurring benign CPA lesions. METHODS Clinical and MR findings of 14 patients with clinical/radiologic (seven) or pathologic (seven) diagnoses of CPA metastasis were retrospectively reviewed. RESULTS Useful clin...

Cerebellopontine Angle Lesions: An Illustratative Review

Proceedings: Differential diagnosis of cerebellopontine angle lesions by vertebral angiography.

LINDSAY SYMON and BRIAN KENDALL (London) had used vertebral angiography for the past five years as a definitive investigation for providing details of the sites and probable natures of cerebellopontine angle lesions. Advantages of angiography were its performance under basal sedation with consequent diminution of the disturbance of intracranial dynamics consequent on anaesthesia, and its potent...

Endolymphatic sac tumor: a rare cerebellopontine angle tumor.

Endolymphatic sac tumors (ELST) are rare papillary tumors of the temporal bone. Previously named as aggressive papillary middle ear tumors, they have recently been shown to arise from the endolymphatic sac. They are a rare in cerebello-pontine angle (CPA). We present a case of an ELST who presented as a CPA tumor with hydrocephalus. He underwent a ventriculo-peritoneal shunt initially. On explo...
