The radiology of epidermoid tumors of the cerebellopontine angle.

摘要: Angiographic, pneumoencephalographic and iophendylate cisternographic features of three recently investigated primary epidermoid tumors the cerebellopontine angle are presented radiology these lesions is reviewed. Modern neuroradiological techniques, including magnification vertebral angiography with subtraction,and fractional pneumoencephalography multidirectional laminographic capability, can provide correct preoperative diagnosis. Combined techniques exclude such as acoustic neuromas, meningiomas, posterior fossa aneurysms arteriovenous malformations. The appropriate studies fully outline lesions, their relationship to adjacent neural vascular structures.
