RESUMO

OBJECTIVE: To describe a case of bilateral sudden sensorineural hearing loss (SSNHL) and intralabyrinthine hemorrhage in a patient with COVID-19. STUDY DESIGN: Clinical capsule report. SETTING: Tertiary academic referral center. PATIENT: An adult woman with bilateral SSNHL, aural fullness, and vertigo with documented SARS-CoV-2 infection (IgG serology testing). INTERVENTIONS: High-dose oral prednisone with taper, intratympanic dexamethasone. MAIN OUTCOME MEASURES: Audiometric testing, MRI of the internal auditory canal with and without contrast. RESULTS: A patient presented with bilateral SSNHL, bilateral aural fullness, and vertigo. Serology testing performed several weeks after onset of symptoms was positive for IgG COVID-19 antibodies. MRI showed bilateral intralabyrinthine hemorrhage (left worse than right) and no tumor. The patient was treated with two courses of high-dose oral prednisone with taper and a left intratympanic dexamethasone injection, resulting in near-resolution of vestibular symptoms, a fluctuating sensorineural hearing loss in the right ear, and a severe to profound mixed hearing loss in the left ear. CONCLUSIONS: COVID-19 may have otologic manifestations including sudden SSNHL, aural fullness, vertigo, and intralabyrinthine hemorrhage.

RESUMO

Acute sialadenitis may be caused by viruses, including coronaviruses. Although there are anecdotal reports of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) salivary gland infections, there have been no well-documented cases of sialadenitis in patients with COVID-19 described in the literature. We report a case of parotitis and submandibular gland sialadenitis, as well as an isolated case of parotitis, in two patients with concurrent SARS-CoV-2 infections. Computed tomography imaging demonstrated parotid and submandibular gland enlargement with heterogenous enhancement and attenuation, consistent with sialadenitis. Medical management was sufficient for successful resolution of the acute sialadenitis. Laryngoscope, 130:2595-2597, 2020.

RESUMO

PURPOSE: Acute stroke treatment requires simple, quick and accurate detection of early ischemic changes to facilitate treatment decisions guided by published selection criteria. The aim of this study was to determine the accuracy and reliability of multiphase computed tomography angiography (mCTA) perfusion hypoattenuation for detecting early severe ischemia. METHODS: Non-contrast CT (NCCT), mCTA for regional leptomeningeal score (mCTA-rLMC), and mCTA perfusion lesion visibility (mCTA-arterial and mCTA-venous) were assessed blinded to clinical information in patients treated with endovascular therapy (EVT). The extent of early ischemia defined by regions of hypoattenuation was evaluated by the Alberta Stroke Program Early CT Score (ASPECTS). The ASPECTS scores were dichotomized based on the American Heart Association (AHA) guidelines for EVT selection, ASPECTS ≥6 vs. <6. The diagnostic accuracy was calculated by comparison to 24-h magnetic resonance imaging (MRI) or CT ASPECTS. Inter-observer reliability of NCCT and mCTA ASPECTS was evaluated. Machine learning models were used to predict the clinical follow-up outcome, e.g. National Institutes of Health Stroke scale (NIHSS) and modified Rankin scale (mRS) from baseline imaging data and patient information. RESULTS: A total of 89 acute stroke patients (68 ± 15 years of age) were analyzed (33 TICI-0, 56 TICI-2b or 3). Median baseline NIHSS was 17. The mCTA-venous had a large effect on accurately identifying early ischemia when dichotomized for ASPECTS ≥6 vs <6 (likelihood ratio [LR+] > 10 vs. [LR-] < 0.29) compared to the moderate effect of NCCT ([LR+] = 6.7; [LR-] = 0.56) and mCTA-rLMC [(LR+ = 8.0; (LR-) = 0.83)]. The inter-observer reliability in mCTA-venous was almost perfect for all ASPECTS regions except the internal capsule. The machine learning support factor regression model identified mCTA-venous as the most important imaging covariate for predicting 24-h NIHSS and 90-day mRS. CONCLUSION: The assessment of mCTA-venous permits a more accurate detection of early ischemia than NCCT and mCTA-rLMC score and is predictive of clinical outcome. We would recommend the inclusion of mCTA perfusion lesion in future endovascular trials aiming at extending current AHA guidelines for EVT in stroke patients with low ASPECTS.
