angle lipomas: report of four cases and review of the literature.
Contrast Enhanced CT (CECT) shows a well-defined cone-shaped homogenous contrast enhancing lesion (23mm x 22mm) in the right Cerebellopontine
Angle (CPA) eccentrically located in the right Internal Auditory Canal (IAC) displacing adjacent cerebellar cortex posteromedially with compression effacement of 4th ventricle with widening of CPA suggested acoustic schwannoma (Fig.
Causes of symptomatic glossopharyngeal neuralgia include cerebellopontine
angle tumors, nasopharyngeal carcinomas, carotid aneurysms, tonsillar abscesses, neurilemmomas of cranial nerve IX, multiple sclerosis, and Eagle syndrome.
Acoustic neuromas account for 90% of cerebellopontine
angle (CPA) lesions, with the other major primary tumors being meningiomas (3%), primary cholesteatomas (2.
The common sites of intracranial lipomas in the decreasing order of frequency include pericallosal region, quadrigeminal/superior cerebellar cistern, suprasellar and cerebellopontine
Correlation of ABR and medical imaging in patients with cerebellopontine
Two infratentorial hypodense homogenously enhancing lesions were seen in the cerebellopontine
angle, causing a widening of internal auditory meatus, so schwannoma was as the most probable diagnosis.

Figure 3: NECT Axial section showing a well-defined hyper dense extra axial lesion noted in the right cerebellopontine
angle and was diagnosed as CP angle Meningioma biopsy proven.
These tumors may grow intracranially and manifest as cerebellopontine
The internal auditory canal and cerebellopontine
angle were normal [Figure 1]d, [Figure 1]e, [Figure 1]f.
They cover, anterior cranial fossa, nasal cavity, and paranasal sinuses; the sellar, parasellar, and clival region; cerebellopontine
angle and jugular fossa; petroclival and lateral skull base; open and endoscopic approaches to the sinonasal cavity and skull base; post-treatment appearance following skull base therapy; and neuroendovascular procedures for skull base neoplasia.
