Pneumo-Membranous Labyrinth After Hyperbaric Oxygen Therapy for Sudden Sensorineural Hearing Loss.

Pneumo-membranous labyrinth is an almost unique condition, in which air extends into the membranous labyrinth, filling the endolymphatic sac through the vestibular aqueduct. In this manuscript, we describe and discuss a case of pneumo-membranous labyrinth, with air bubbles extending also to the endolymphatic sac, resulting in anacusis, following hyperbaric oxygen therapy for sudden sensorineural hearing loss. The patient was successfully rehabilitated with a cochlear implant, obtaining a pure-tone average of 30 dB, with a speech discrimination score of 100% at 70 dB.

Vertebrobasilar and Basilar Dolichoectasia Causing Audio-Vestibular Manifestations: A Case Series with a Brief Literature Review.

Audio-vestibular symptoms can arise from vertebrobasilar dolichoectasia (VBD) and basilar dolichoectasia (BD). Given the dearth of available information, herein we reported our experience with different audio-vestibular disorders (AVDs) observed in a case series of VBD patients. Furthermore, a literature review analyzed the possible relationships between epidemiological, clinical, and neuroradiological findings and audiological prognosis.

A singular case of hyposmia and transient audiovestibular post-vaccine disorders: case report and literature review.

Introduction: Rare and mild adverse effects on cranial nerves have been reported after vaccination. Here, we report a singular case of smell and taste disorder associated with tinnitus that occurred after Oxford-AstraZeneca vaccination together with a review of the available literature.

Case Presentation: A 76-year-old patient experienced smell disorder, ear fullness and tinnitus 2 days after the first dose of Oxford-AstraZeneca vaccine.

Magnetic Resonance Imaging Confirmed Olfactory Bulb Reduction in Long COVID-19: Literature Review and Case Series.

An altered sense of smell and taste was recognized as one of the most characteristic symptoms of coronavirus infection disease (COVID-19). Despite most patients experiencing a complete functional resolution, there is a 21.3% prevalence of persistent alteration at 12 months after infection.

Temporal bone high-resolution computed tomography in non-syndromic unilateral hearing loss in children.

Objective: The aim of this study was to disclose possible inner ear abnormalities/pathologies by means of high-resolution computed tomography (HRCT) of the temporal bone (TBHRCT) in children with unilateral hearing loss (UHL).

Methods: Retrospective review of audiological evaluation and TBHRCT in 22 children with UHL.

Results: Two thirds of the children showed profound hearing loss.

Sudden hearing loss in sarcoidosis: otoneurological study and neuroradiological correlates.

Sarcoidosis is an inflammatory multisystem disorder of unknown cause. Approximately 5-7% of patients manifest symptoms of central nervous system involvement, or neurosarcoidosis. Cranial neuropathy usually entails facial nerve palsy and optic neuritis.

Primary and metastatic intraaxial brain tumors: prospective comparison of multivoxel 2D chemical-shift imaging (CSI) proton MR spectroscopy, perfusion MRI, and histopathological findings in a group of 159 patients.

Background: This study aims to assess the diagnostic value of multivoxel 2D chemical-shift imaging (CSI) proton magnetic resonance (MR) spectroscopy combined with perfusion magnetic resonance imaging (MRI) in the differential diagnosis and grading of brain tumors by comparing neuroimaging data with histopathological findings obtained after resection or biopsy.

Methods: A total of 159 patients with a previous brain tumor diagnosis underwent multivoxel 2D CSI proton MR spectroscopy and perfusion MRI. MR spectroscopy multivoxel 2D CSI was performed with an echo time of 30, TR 1,500, FOV 160 mm, acquisition time 7 min 34 s.

Identification of a novel mutation in the SLC26A4 gene in an Italian with fluctuating sensorineural hearing loss.

Pendred syndrome is an autosomal recessive disorder characterized by congenital sensorineural deafness, goitre and defective iodide organification. Congenital and profound hearing loss is the hallmark of the syndrome, while goitre and thyroid dysfunction are highly variable even within the same family. Clinical features are due to altered formation of pendrin, a chloride/iodide transporter protein expressed in the inner ear, thyroid gland and kidney.

Systematic approach to human error in radiology.

We propose a systematic approach to human errors in radiology. We consider perceptual, cognitive and system errors. Practical aspects with psychological and clinical involvement are discussed with tree diagrams.
