Herpes zoster oticus: Correlations between Clinical and MRI Findings

Abstract: Many gadolinium-enhanced magnetic resonance imaging (MRI) studies focusing on the anatomy and pathology of the 7th cranial nerve have already been published. However, only scattered cases of herpes zoster oticus (HZO) have been described and only the MRI appearance of the soft temporal bone structures has been reported. Enhanced MRI was performed in 4 patients with HZO observed at the Department of Otorhinolaryngology of the University of Pisa. A good correlation was found between the clinical data and MRI fin… Show more

“…1 Despite efforts to clarify its pathophysiologic characteristics, the cause of ISSNHL remains unclear. The hypothesized causes include viral infection, 2 vascular compromise, 3 disruption of cochlear membranes, 4 and the autoimmunity. 5 However, detailed investigation based on medical and physical examination, audiovestibular tests, blood examinations, and brain magnetic resonance imaging (MRI) studies with and without gadolinium administration shows a specific cause only in about 10% of patients.…”

“…Neither increased permeability of contrast media nor inflammatory nerve edema in the IAC was demonstrated ( Figure 3A), which is opposed to the concept that the varicella-zoster virus may break down the blood-labyrinth barrier and increase the permeability of contrast media. 19,20 To verify the concept, another 43-year-old male patient with herpes zoster oticus, manifested by eruption, facial paresis, and hearing loss on the right ear, was adopted for comparison. 16 Serological assay confirmed the reactivation of varicella-zoster virus, and MR imaging demonstrated a linear gadolinium-enhanced lesion in the IAC of the right ear ( Figure 3B).…”
