Pressure Effects on Cranial Nerves:
. Vestibular Nerve (CN VIII): Deafness, vertigo, tinnitus (DVT).
. Facial Nerve (CN VII): Facial weakness or drooping.
. Abducens Nerve (CN VI): Diplopia.
. Trigeminal Nerve (CN V): Loss of corneal reflex and facial sensation.
Additional Symptoms:
. Feeling of fullness in the affected ear.
. Symptoms of increased intracranial pressure (e.g., headache) due to the space-occupying nature of the lesion.
Investigations:
i. MRI of the Cerebellopontine Angle: Preferred imaging to confirm the diagnosis.
ii. MRI of the Internal Auditory Meatus: To assess the extent of the tumor.
iii. MRI Brain: To rule out other intracranial pathologies.
Management:
i. Observation: For small, asymptomatic tumors.
ii. Surgical Resection: For larger or symptomatic tumors.
iii. Radiotherapy: An option for patients who are not surgical candidates or for residual tumor control post-surgery.
