Otolaryngologic Clinics of North America, 1988
Acoustic neuromas account for approximately 80 to 90 per cent of cerebellopontine angle tumors. Useful imaging studies include (1) high-resolution CT of the internal auditory canals using extended scale and "bone algorithm" techniques, (2) infusion study of the cerebellopontine cisterns, (3) gaseous or opaque CT cisternography, and (4) MRI.

Lipoma of the cerebellopontine angle
American Journal of Otolaryngology, 2006Lipomas of the cerebellopontine angle (CPA) are unusual tumors that typically present with hearing loss, tinnitus, dizziness, and occasionally facial neuropathies. We describe the case of a healthy 42-year-old woman who presented with left-sided hearing loss and facial synkinesis.

Hemangioblastoma of the Cerebellopontine Angle
Archives of Otolaryngology–Head & Neck Surgery, 2010Tumors of the cerebellopontine angle (CPA) constitute 6% to 10% of all intracranial neoplasms. Most are vestibular schwannomas (VSs) and meningiomas, but as many as 1 in 5 CPA lesions are of other etiologies. 1,2 Hemangioblastomas (HMBs), which are highly vascular tumors of the central nervous system, represent up to 12% of infratentorial ...

Imaging of the cerebellopontine angle
Practical Neurology, 2014Disease involving the cerebellopontine angle (CPA) may arise from structures located within the cistern or from extension of lesions located primarily outside the cistern—from the brainstem, fourth ventricle, choroid plexus and bony skull base. The symptoms and signs of CPA disease are non-specific, relating either to compression of the neural ...

Neurosurgery, 1983
Abstract Lipomas located in the cerebellopontine angle(CPA) have rarely been reported. With the advent of computed tomographic scanning and more sophisticated physiological diagnostic techniques, CPA lipomas are being reported more frequently. This paper reviews the world's literature on this lesion and summarizes the symptoms and signs,

Transotic Approach to the Cerebellopontine Angle
Neurosurgery Clinics of North America, 1992The transotic approach to the cerebellopontine angle for resection of tumors invading the internal auditory canal provides superior illumination and exposure for optimal preservation of facial nerve function. Separation of facial nerve from tumor is enhanced with an anterior exposure that allows visualization of the intracranial segment of the nerve ...

Endoscopy of the Cerebellopontine Angle
Endoscopy, 1978Endoscopy of the pontine angle ("cisternoscopy") is a decisive diagnostic procedure in clarifying pathological processes in this region. Using a retrolabyrinthal approach through the mastoid bone, the endoscopes are inserted in the pontine angle for direct inspection. In the present study the method and the diagnostic results are described.

Cerebellopontine angle myelography
Journal of Neurosurgery, 1972✓ Review of more than 1400 positive-contrast myelograms of the posterior fossa performed at the Mayo Clinic indicates that this is an excellent method for depicting normal and pathological anatomy in the basal cisterns, if an adequate amount of medium and a precise technique are used.
