Abstract
OBJECTIVE To examine the otologic and neurotologic symptoms, physical examination findings, and imaging features secondary to hematologic malignancies. METHODS Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, databases, including PubMed, Scopus, and CINAHL, were searched for articles including patients with otologic manifestations of leukemia, lymphoma and multiple myeloma. Data collected included patient and study demographics, specific hematologic malignancy, timing and classification of otologic symptoms, physical examination findings, imaging features and methods of diagnosis. Pooled descriptive analysis was performed. RESULTS Two hundred seventy-two articles, of which 255 (93.8%) were case reports and 17 (6.2%) were case series, reporting on 553 patients were identified. Otologic manifestations were reported on 307 patients with leukemia, 204 patients with lymphoma and 42 patients with multiple myeloma. Hearing loss and unilateral facial palsy were the most common presenting symptoms for 111 reported subjects with leukemia (n = 46, 41.4%; n = 43, 38.7%) and 90 with lymphoma (n = 38, 42.2%; n = 39, 43.3%). Hearing loss and otalgia were the most common presenting symptoms for 21 subjects with multiple myeloma (n = 10, 47.6%; n = 6, 28.6%). Hearing loss and unilateral facial palsy were the most common otologic symptoms indicative of relapse in subjects with leukemia (n = 14, 43.8%) and lymphoma (n = 5, 50%). CONCLUSION Hearing loss, facial palsy, and otalgia might be the first indication of a new diagnosis or relapse of leukemia, lymphoma, or multiple myeloma. Clinicians should have a heightened level of suspicion of malignant etiologies of otologic symptoms in patients with current or medical histories of these malignancies.

Abstract
A 72-year-old woman presented with rapidly progressive hearing loss and neuropsychiatric symptoms without other focal neurological symptoms. Progressive sequential sensorineural hearing loss (SNHL) was demonstrated on serial audiology. A diagnostic approach to SNHL is reviewed. Lumbar puncture revealed elevated protein, low glucose, and pleocytosis with poorly differentiated cells, and a differential diagnosis is discussed. MRI brain revealed gadolinium enhancement within the internal auditory canals bilaterally as well as the left cochlea. A malignancy workup revealed right axillary lymphadenopathy. Biopsy revealed poorly differentiated breast adenocarcinoma, with identical cells to those in the cerebrospinal fluid. The patient was treated with intrathecal methotrexate with no effect on the patient's hearing. In this case, rapidly progressive SNHL was the presenting feature of widely metastatic breast adenocarcinoma with leptomeningeal carcinomatosis, highlighting the need to search for a central cause for this presentation.

Abstract
OBJECTIVE Cochleovestibulopathy is a distinguishable paraneoplastic phenotype. In this study, we evaluate clinical presentation, serological/cancer associations and outcomes of paraneoplastic cochleovestibulopathy. METHODS Retrospective chart review of patients with hearing impairment and/or vestibulopathy who underwent serological evaluations for paraneoplastic antibodies between January 2007 and February 2021 was performed. RESULTS Twenty-six patients were identified (men, n=23; median age, 45 years, range: 28-70). Biomarkers detected included: KLHL11-IgG (n=20, 77% (coexisting LUZP4-IgG, n=8)), ANNA1-IgG (n=3, 12%), amphiphysin-IgG (n=2, 8%) and LUZP4-IgG (n=1, 4%). Most common neoplastic association was testicular/extra-testicular seminoma (n=13, 50%). Hearing impairment (bilateral, 62%) was present in all patients. Fifteen patients (58%) had cochleovestibular dysfunction as their initial presentation before rhombencephalitis/encephalomyelitis manifestations (hearing loss, four; acute vertigo, eight; both, three). Brain MRI demonstrated internal auditory canal enhancement in four patients. Audiometry commonly revealed severe-profound bilateral sensorineural hearing loss. Most patients had a refractory course despite immunotherapy and/or cancer treatment. CONCLUSION Cochleovestibulopathy commonly presents with rapidly progressive bilateral hearing loss and/or acute vertigo. However, in some patients, these symptoms present along with or following brainstem/cerebellar manifestations. KLHL11-IgG and seminoma are the most common serological and cancer associations, respectively. Recognition of this phenotype may aid in earlier diagnosis of paraneoplastic autoimmunity and associated cancer.

Abstract
ABSTRACT A 45-year-old man with a history of testicular seminoma treated 8 years earlier presented with chronic progressive truncal and limb ataxia, progressive sensorineural hearing loss, and episodic vertigo. Eye movement and neuro-otology examinations showed localizing abnormalities to the bilateral cerebellar flocculus, vermis, and bilateral cerebellar hemispheres. Audiometric testing showed bilateral symmetric sensorineural hearing loss. There was a normal MRI of the brain. Cerebrospinal fluid (CSF) showed modest lymphocytic pleocytosis, and there was an elevated serum choriogonadotrophic hormone. An abdominal CT scan showed a solitary, large retroperitoneal lymph node, and histopathologic examination of the node biopsy showed granulomatous inflammation without microorganisms; eventually, immunohistochemical markers confirmed the diagnosis of metastatic seminoma. Although normal neuroimaging and inflammatory CSF reaction suggested a paraneoplastic etiology, the initial paraneoplastic antibody testing was negative. Subsequent investigation identified a positive kelch-11 protein antibody, thus confirming the paraneoplastic connection between the metastatic seminoma and the subacute neurologic-cochleovestibular syndrome.

Abstract
Thymomas are counted among the rare tumour entities which are associated with autoimmune disorders (AIDs) and paraneoplastic syndromes (PNS) far more often than other malignancies. Through its complex immunological function in the context of the selection and maturation of T cells, the thymus is at the same time highly susceptible to disruptive factors caused by the development and growth of thymic tumours. These T cells, which are thought to develop to competent immune cells in the thymus, can instead adopt autoreactive behaviour due to the uncontrolled interplay of thymomas and become the trigger for AID or PNS affecting numerous organs and tissues within the human body. While myasthenia gravis is the most prevalent PNS in thymoma, numerous others have been described, be they related to neurological, cardiovascular, gastrointestinal, haematological, dermatological, endocrine or systemic disorders. This review article sheds light on the pathophysiology, epidemiology, specific clinical features and therapeutic options of the various forms as well as courses and outcomes of AID/PNS in association with thymomas. Whenever suitable and backed by the limited available evidence, the perspectives from both the thymoma and the affected organ/tissue will be highlighted. Specific issues addressed are the prognostic significance of thymectomy on myasthenia gravis and other thymoma-associated AID/PND and further the impact and safety of immunotherapies on AID and PND relating to thymomas.

Abstract
Objective The association between comorbidities and inpatient mortality with sudden sensorineural hearing loss (SSNHL) has not been investigated. Therefore, this study aimed to provide a 14-year nationwide incidence, and identify risk factors and comorbidities of SSNHL inpatient mortality. Methods Data were obtained from the Taiwan National Health Insurance Research Database for 2000 to 2013. Inpatient mortality of 31,258 patients hospitalized with a diagnosis of SSNHL was recorded and analyzed. Results Sixteen patients with SSNHL exhibited mortality with a percentage of 0.05% and an incidence of less than 0.01 per 100,000 people per year. The risk of variables among inpatient mortality was associated with older age (adjusted odds ratio [OR]: 1.042, 95% confidence interval [CI]: 1.009–1.077) and the presence of catastrophic illness (adjusted OR: 4.949, 95% CI: 1.290–18.996). Potential comorbidities included hematologic diseases, cancers, chronic hepatitis, gastrointestinal bleeding, chronic obstructive pulmonary disease, seizures or convulsions, coronary artery disease, diabetes mellitus, and varicose veins and their associated complications. Conclusions This 14-year nationwide study shows that inpatient mortality rate for SSNHL is relatively rare, but suggests we should still be aware of the potential for such underlying conditions to cause SSNHL as well as the mortality associated with these conditions.

Abstract
PURPOSE Bilateral vestibulopathy (BV) is an uncommon disorder and the etiology remained idiopathic in most cases. Delayed 3D-FLAIR sequences have provided new insights into various inner ear diseases, allowing the evaluation of the endolymphatic space and the permeability of the blood-labyrinthine barrier (BLB). The aim of this study was to assess both the morphology of the endolymphatic space and the permeability of the BLB in patients with BV as evaluated by delayed 3D-FLAIR sequences. METHODS In this retrospective study, we performed 3D-FLAIR sequences 4 h after administering contrast media to 42 patients with BV. Two radiologists independently evaluated the morphology of the endolymphatic space (either vestibular atelectasis or endolymphatic hydrops) and the permeability of the BLB. RESULTS Morphologic anomalies of the endolymphatic space and vestibular blood-labyrinthine barrier impairment were observed in 59.6% of patients with BV. Bilateral vestibular atelectasis (VA) was found in 21 patients (50%), involving only the utricle and all three ampullas while the saccule was always observed with no sign of collapse: idiopathic BV (n = 19), aminoglycoside administration (n = 1) and few days following abdominal surgery (n = 1). One patient had bilateral vestibular malformation. BLB impairment was observed in five patients (11.9%): paraneoplastic (n = 1), lymphoma (n = 1), autoimmune (n = 1), and vestibular "neuritis" (n = 2). Seventeen patients (40.4%) had normal MRI with no endolymphatic space anomaly or BLB impairment. CONCLUSION Patients with BV presented with morphologic anomalies of the endolymphatic space or BLB impairment in 59.6% of patients.

Abstract
OBJECTIVE Paraneoplastic syndromes associated with thymomas remain incompletely understood. The objective was to examine the association between surgically resected thymomas and paraneoplastic syndromes over the past half century. METHODS A primary PubMed/MEDLINE search was used to identify published articles describing paraneoplastic syndromes associated with thymomas from 1960 to 2019. A secondary search identified additional articles referenced in the articles found in the primary search. Kaplan-Meier and log-rank test were used for time-to-event data analyses. RESULTS From 407 articles describing 507 patients, 123 different paraneoplastic syndromes were associated with thymoma. The 5 most common paraneoplastic syndromes were myasthenia gravis, pure red cell aplasia, lichen planus, Good syndrome, and limbic encephalitis. Complete or partial resolution of paraneoplastic syndrome symptoms after surgery was noted in 76% of patients, of whom 21% had a relapse or new paraneoplastic syndrome onset after surgery. The most common adjunctive therapy associated with resolution of paraneoplastic syndrome was corticosteroids (30%). For all patients after surgery, thymoma recurrence was observed in 17% of cases, whereas recurrence of paraneoplastic syndrome was observed in 34% of cases, and both were observed in approximately 11% of cases. The 5- and 10-year overall survivals were 78% and 66%, respectively. Improved overall survival was associated with patients who had total resolution from paraneoplastic syndrome. CONCLUSIONS A comprehensive assessment of publications over the past half century suggests that a multimodal treatment approach that includes surgical resection of thymomas is able to achieve paraneoplastic syndrome resolution in a majority of patients. Onset of new paraneoplastic syndromes after surgery is associated with the recurrence of the first paraneoplastic syndrome, and resolution of paraneoplastic syndrome is associated with improved overall survival.

Abstract
The purpose of this study was to consider the possible role of autoimmune diseases and paraneoplastic syndrome in the genesis of tinnitus. The incidence of autoimmune inner ear disease (AIED) is rare, accounting for <1% of all cases of hearing impairment and dizziness. In presence of auditory and vestibular deficit in oncological patients, a paraneoplastic syndrome with cochleovestibulopathy should be considered. We described a 50-year-old Caucasian woman came to our attention with complaints of severe disabling bilateral tinnitus (Tinnitus Handicap Inventory, THI: 96), ear fullness and headache. The onset of tinnitus was associated to the last breast implant and prolonged antibiotic therapy. Serological autoimmunity tests were positive and a diagnosis of mixed connective tissue disease with notes of fibromyalgia was made. Pure tone audiometry testing revealed bilateral fluctuating mild hearing loss on high frequencies. The tinnitus was successfully treated with bilateral wideband sound generators (listening 8-9 h for day) regulated at the mixing point. At 12 months follow up THI has shrunk considerably (THI: 4) and the patient has continued treatment only with the sound pillow. In conclusion significant progress is needed to better understand the role of autoantibodies in the pathogenesis and diagnosis of paraneoplastic cochleovestibulopathy. To our knowledge, our study is the first in which hearing loss and tinnitus is considered as a manifestation of a paraneoplastic syndrome.
