Question: Idiopathic intracranial hypertension may commonly cause which of the following secondary symptoms?

Options:

• Conductive hearing loss
• Sensorineural hearing loss
• Pulsatile tinnitus
• Persistent tinnitus

Correct Answer: Pulsatile tinnitus

Explaination: Pulsatile tinnitus is a common complaint of patients with idiopathic intracranial hypertension, which is related to a pressure gradient between the cranial and cervical vascular structures, causing a bruit. Patients generally report a whooshing sound without tone. Persistent tinnitus is a more constant, tonal type of tinnitus. Associated causes vary widely, including ototoxic medications, Meniere disease, hearing loss, head injury, and others. The pathophysiology of persistent tinnitus is not well understood. Palatal myoclonus consists of rhythmic myoclonic activity of the soft palate with associated clicking sound. This may relate to Whipple disease, gluten sensitivity, or structural disruption of the Guillain- Mollaret triangle.
