"Metastases and extra-axial primary malignancies are often initially misdiagnosed as benign disease  due to the fact that physical examination, clinical history, and audiovestibular testing are often unhelpful in discriminating the type of lesion because the involvement of CPA tumor is similar to a vestibular schwannoma with hearing loss, tinnitus, facial weakness, and disequilibrium . Adhesion of the tumor to cranial nerves and surrounding tissues at surgery suggests uncommon tumor entities  "
[Show abstract][Hide abstract] ABSTRACT: The appearance of a primary germinoma in the central nervous system but not on or near the midline or within the brain is exceptional. It may occur at any age; however, it is rare in patients over 50 years old. Only a handful of cases of germinomas located in the cerebellopontine angle were presented, but to our knowledge, there has been no description of an isolated germinoma in the internal auditory canal. We report a case of germinoma in the internal auditory canal in a 51-year-old man simulating the clinical and radiological characteristics of a vestibular schwannoma.
