Spontaneous Labyrinthine Hemorrhage: A Case Series

Abstract

We present the largest cohort of patients with radiographic diagnosis of labyrinthine hemorrhage using T1 and FLAIR signal abnormalities on MRI. Most patients presented with a profound unilateral sudden SNHL that did not recover. Our findings are consistent with prior reports that abnormal FLAIR signal on MRI is a reliable marker for detecting inner ear injury and can potentially be used as a marker for poor prognosis.
