Résumé
To describe the histopathologic findings and clinical presentation of arachnoid cysts (ACs) within the human temporal bone. Retrospective cohort analysis. An analysis of all medical records of patients diagnosed with an AC was performed. Temporal bones underwent standard processing for histologic examination. The slides were examined by light microscopy. The histologic findings were compared to premortem clinical data. Twenty-seven ACs were identified in 22 patients. Twenty ears (74%) had no identified risk factor for AC development. The median volume was 12.8 mm AC of the IAC is not uncommon. Its presentation is variable, ranging from asymptomatic to SNHL, with poor speech discrimination, tinnitus, and vertigo. This diagnosis should be kept in the differential diagnosis of retrocochlear pathologies. 4 Laryngoscope, 129:1667-1674, 2019.
