“…The location of tumor, the size and presenting symptoms particularly preoperative hearing are special issues the surgeon must consider before choosing a surgical approach [8]. The ultimate surgical approach is one that gives the surgeon a wide access to the whole tumor with minimal brain manipulation and minimal morbidity related to additional CN deficits as well as single stage total tumor removal [8].…”

“…The ultimate surgical approach is one that gives the surgeon a wide access to the whole tumor with minimal brain manipulation and minimal morbidity related to additional CN deficits as well as single stage total tumor removal [8]. Furthermore, to accomplish a total tumor resection, the surgical procedures should be well designed, since recurrent operation increases the risk of lower cranial nerve injuries and incomplete removal involves inevitable reappearance [8]. The common surgical approaches approach includes post-au- …”

“…Many authors have further categorized the intracranial types above into intrajugular schwannomas since they usually extend into the jugular foramen and make up the majority of cases, and intracisternal schwannomas because there are located at the cisterna magna [3] [6] [7]. The most common clinical presentations of most schwannomas extending to the jugular region are cranial nerve dysfunction, such as hearing impairment, dysphagia, and difficulty in phonation although the clinical manifestations of these tumors vary in relations to tumor location and the magnitude of their growth [8], while intracisternal tumors present with cerebellar signs and myelopathy [3] [9]. We present a case and also review the appropriate surgical techniques we could have use to access the tumor in our patient since the goal of surgical approach is to have enough expose to the lesion, no matter how extended the tumor maybe.…”

Background: Intracranial schwannomas of the accessory nerve are very rare lesions. They are categorised according to their locations into either intrajugular or intracistemal schwannomas although most of them are intrajugular. The intrajugular type constitutes about 2% to 4% of all intracranial schwannomas described in literature. Aim: It's very unusual for an accessory nerve to mimic glossopharyngeal nerve looking at the anatomical location of the accessory nerve. Although many authors have written on accessory nerve, none have described this unusual presentation. We present a case, management as well as review on the classification and appropriate surgical techniques we could have use to access the tumor in our patient since the choice of a particular surgical approach is based on the nature of tumor, location as well as it extension into other adjacent structures. Case Presentation: We present a case of 52-year-old woman with very unusual accessory nerve schwannoma which mimics the clinical presentation of glossopharyngeal nerve tumor. The main symptom in our case is six (6) months history of deviation of the tongue to right side with dizziness and change of voice. Conclusion: The unusual presentation in our case could be due to massive compression of glossopharyngeal nerve by the growing accessory nerve schwannoma since most lower cranial nerve schwannomas at this location will almost always course compressive symptoms.
