متن کامل[Epidermoid cyst of the cerebellopontine angle].
Results: Chart review identified 17 patients. The most common symptom at diagnosis was tinnitus, followed by sensorineural hearing loss, vertigo, facial pain, and headache. Physical exam revealed facial hypesthesias in 3 patients, facial paresis in 2 patients, while 14 patients had no physical exam findings on presentation.

متن کاملCerebellopontine Angle Epidermoid Cyst: Case Report
Epidermoid cysts are rare congenital tumors of the central nervous system (CNS), histologically benign and slowgrowing lesions. Their frequency among primitive intracranial tumors is about 1% and they account for 40% of all intracranial epidermoid of the cerebellopontine angle (CPA); there they constitute the third most frequent neoplasm (5%), after acoustic neuromas and meningiomas. We report ...
متن کاملUnusual CT and MR appearance of an epidermoid tumor of the cerebellopontine angle.
We present a case of an unusual epidermoid tumor of the cerebellopontine angle that appeared hyperdense on CT scans and hyperintense on T1- and T2-weighted MR images. We believe that these imaging characteristics were caused by a high protein concentration within the contents of the cyst.
متن کاملEpidermoid tumor of the cerebellopontine angle: signal loss in the contralateral cistern.
We report a case of an epidermoid tumor of the right cerebellopontine angle (CPA) in which the contralateral CPA cistern showed abnormal, low signal intensity on T2-weighted fast spin-echo MR images. Diffusion-weighted images showed the epidermoid tumor of the right CPA extending to the prepontine cistern. The cause of the abnormal signal intensity was proved to be an artifactual signal loss du...
