- Vestibular neuritis, one of common causes of acute spontaneous vertigo, is characterized by a sudden onset of vertigo with horizontal-torsional spontaneous nystagmus and unsteadiness with a falling tendency. Herpes zoster is a common infection caused by varicella-zoster virus (VZV), and herpes zoster ophthalmicus (HZO) occurs when this virus is reactivated in the ophthalmic branch of the trigeminal nerve. VZV can cause vestibular neuritis with cochlear dysfunction as a form of herpes zoster oticus, also known as Ramsay-Hunt syndrome. However, to our knowledge, isolated vestibular neuritis associated with HZO has been rarely reported, because of distance between the trigeminal nerve and the vestibulocochlear nerve. We present an unusual case of vestibular neuritis complicated by the HZO.

Abstract

- Cavernous sinus syndrome is characterized by multiple cranial nerve palsies manifesting with ophthalmoplegia, ptosis, facial sensory loss due to involvement of adjacent cranial nerves. Tumor, trauma, and non-infectious inflammatory disorders are principal causes of cavernous sinus syndrome. Rhinocerebral mucormycosis is one of the fatal causes of cavernous sinus syndrome usually in immunocompromised patients. Here is a case of cavernous sinus syndrome complicating occlusion of the internal carotid artery by necrotizing fungal sinusitis, which is highly suspicious of rhinocerebral mucormycosis with non-immunocompromised state.
