Sudden sensorineural hearing loss as the first manifestation of chronic myeloid leukaemia: case report

Bilateral cochlear fibrosis complicating chronic myeloid leukemia: A CARE case report

PURPOSE

We report the second case of bilateral sudden sensorineural hearing loss with intracochlear fibrosis due to chronic myeloid leukemia.

CASE REPORT

A 44-year-old man presented to the emergency department with rapidly progressive bilateral hearing loss, tinnitus and vertigo, associated with dyspnea. Chronic myeloid leukemia complicated by pulmonary and cochleovestibular leukostasis was diagnosed, and cytoreductive treatment was started. Despite this treatment, bilateral total hearing loss and complete vestibular deficit persisted. MRI showed bilateral labyrinthitis, and emergency cochlear implantation was indicated. During surgery, inflammatory intracochlear tissue made electrode array insertion possible only against resistance. One year after implantation, there was significant improvement in speech recognition and communication scores.

CONCLUSION

In case of sudden sensorineural hearing loss induced by chronic myeloid leukemia, treatment should be as fast as possible, with prompt cochlear implantation in case of definitive profound hearing loss, because of the risk of cochlear fibrosis and ossification.

A Scoping Review of Otologic Manifestations of Hematologic Malignancies

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.

Bilateral intracochlear hemorrhage: A rare onset of chronic myelogenous leukemia

Acute onset of vertigo and hearing loss is rare in leukemic disorders. MRI can diagnose intracochlear hemorrhage as the underlying cause. The hearing can improve but if severe hearing loss preserves, cochlear implantation can be considered.

Sensorineural Hearing Loss in Juvenile CML: A Rare Case Report in Surabaya, Indonesia

Chronic myeloid leukemia (CML) is a type of myeloproliferative neoplasm (MPN) in which granulocytes are the primary proliferating cells. CML in pediatric patients (juvenile CML) is an uncommon MPN, representing 2–3% of children newly diagnosed with leukemia. Sensorineural hearing loss that progresses rapidly is an uncommon early sign of a hematological disorder in patients with CML. This article presents the case of a 10-year-old patient with complaints of bilateral hearing loss for 2 weeks. Pure-tone audiometry indicated sensorineural hearing loss of the left ear and mixed hearing loss of the right ear. After an in-depth evaluation of a bone marrow smear and positivity for the BCR-ABL fusion gene, it was concluded that the patient had chronic-phase juvenile CML. However, hearing loss recovery after hydroxyurea therapy could not be observed because the patient died after suffering an uncontrolled seizure on day 14 of hospitalization.

Profound Sudden Sensorineural Hearing Loss in Hematologic Malignancy: A Case for Urgent Cochlear Implantation With Discussion and Systematic Review of the Literature

OBJECTIVE

To perform a systematic review of sensorineural hearing loss (SNHL) in hematologic malignancy; to describe an illustrative case of urgent cochlear implantation for bilateral profound SNHL and vestibular hypofunction in hyperviscosity syndrome; to suggest an approach to management of hyperviscosity syndrome-associated deafness with cochlear implantation.

DATA SOURCES

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, systematic search of PubMed and Embase databases was undertaken for articles detailing clinical information about SNHL caused directly by hematologic malignancies.

RESULTS

A total of 37 studies from 1989 to 2020 were qualitatively reviewed, the majority of which were case studies or case series. Causes of hearing loss in hematologic malignancy were found to include hyperviscosity syndrome, labyrinthine hemorrhage, infiltration, and infection. Patients with profound SNHL in hematologic malignancies from hyperviscosity syndrome may be candidates for cochlear implantation, and are also at increased risk for cochlear ossification. We review previous cases for their diagnostic approach, treatment paradigm, and outcomes data, and propose an approach to management.

CONCLUSION

Bilateral sudden profound SNHL and vestibular hypofunction is a presenting symptom of hyperviscosity syndrome in hematologic malignancy. Although this entity is rare and previous reports have suggested improvement in hearing with oncologic treatment, cases with profound hearing loss are unlikely to recover serviceable hearing. We advocate for early magnetic resonance imaging with attention to fluid signal in the inner ear and serial audiometric follow-up to guide clinical decisions. We advise early consideration for cochlear implantation.

Sudden Sensorineural Hearing Loss Associated with Nutritional Anemia: A Nested Case-Control Study Using a National Health Screening Cohort

Previous studies have suggested an association of anemia with hearing loss. The aim of this study was to investigate the association of nutritional anemia with sudden sensorineural hearing loss (SSNHL), as previous studies in this aspect are lacking. We analyzed data from the Korean National Health Insurance Service-Health Screening Cohort 2002-2015. Patients with SSNHL (n = 9393) were paired with 37,572 age-, sex-, income-, and region of residence-matched controls. Both groups were assessed for a history of nutritional anemia. Conditional logistic regression analyses were performed to calculate the odds ratios (ORs) (95% confidence interval, CI) for a previous diagnosis of nutritional anemia and for the hemoglobin level in patients with SSNHL. Subgroup analyses were conducted for age and sex. Age, sex, income, and region of residence were stratified. Obesity, smoking, drinking alcohol, systolic/diastolic blood pressure, fasting blood glucose, total cholesterol, and the Charlson Comorbidity Index were considered in the regression models. Nutritional anemia was present in 4.8% (449/9393) of patients with SSNHL and 4.0% (1494/37,572) of controls (p < 0.001). The SSNHL group demonstrated 1.20-fold higher odds for nutritional anemia (95% CI = 1.08-1.34, p = 0.001). Hemoglobin levels were not associated with SSNHL. In subgroups <60 years old, there was a consistent positive association of nutritional anemia with SSNHL (adjusted OR = 1.55, 95% CI = 1.11-2.15, p = 0.010 for men <60 years old, and adjusted OR = 1.22, 95% CI = 1.02-1.45, p = 0.028 for women <60 years old). Nutritional anemia, but not hemoglobin level, was associated with an increased risk of SSNHL.
