“…2 Extracutaneous HN JXG has been reported in locations such as the tympanic membrane, nasal cavity, tongue, orbit and paranasal sinus, subglottis, cervical spine, skull base including the temporal bone, intracranial compartment, and HN muscles. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] Cutaneous JXG typically presents as a solitary macule or papule with a flesh-colored, erythematous, or yellowish hue. 2 In such cases, radiographic imaging is not indicated.…”

“…In human beings, recommended treatment for symptomatic intracranial cholesterol granulomata is surgical resection (Grossi and others 2008, Kasliwal and others 2008). An improved ability to diagnose these masses antemortem may encourage the development of curative, surgical treatment in horses.…”

“…Bilateral tumors in the IAC/CPA that do not have classic radiologic findings typical of schwannoma can be a diagnostic dilemma. Reported bilateral tumors of the IAC/CPA include: Cartilaginous tumors,[ 5 ] xanthogranulomas,[ 17 ] choroid plexus papillomas,[ 6 ] endolymphatic sac tumors,[ 18 ] metastatic tumors including adenocarcinoma and melanomas,[ 11 14 ] meningiomas,[ 32 ] and lipomas. [ 9 ] For atypical IAC/CPA masses, emphasis should be placed on imaging characteristics as these may aid in diagnosis before surgical intervention.…”

Background:Gangliogliomas are rare low grade, typically well-differentiated, tumors that are composed of mature ganglion cells and neoplastic glial cells. These tumors can appear at virtually any location along the neuroaxis but classically occur in the temporal lobe of young patients. In a small number of cases, gangliogliomas have presented as masses in the brainstem or involving cranial nerves. With the exception of vestibular schwannomas, bilateral tumors in the region of the internal auditory canal (IAC) or cerebellopontine angle (CPA) are exceedingly rare.Case Description:We report a case of a 58-year-old male who presented with hearing loss, tinnitus, and vertigo. Initial magnetic resonance imaging revealed bilateral nonenhancing IAC/CPA tumors. Based on this finding, a presumptive diagnosis of neurofibromatosis Type II was made, which was initially managed conservatively with close observation. He returned for follow-up with worsening vertigo and tinnitus, thus prompting the decision to proceed with surgical resection of the symptomatic mass. Intriguingly, pathological study demonstrated a WHO Grade I ganglioglioma.Description:We report a case of a 58-year-old male who presented with hearing loss, tinnitus, and vertigo.

Intriguingly, pathological study demonstrated a WHO Grade I ganglioglioma.Conclusion:This is the first reported case of bilateral IAC/CPA gangliogliomas. When evaluating bilateral IAC/CPA lesions with unusual imaging characteristics, ganglioglioma should be included in the differential diagnosis.
