RESUMEN
Anterior Inferior cerebellar artery infarction misdiagnosed as inner ear disease. OBJECTIVE: The clinical >resentation of anterior inferior cerebellar artery (AICA) infarction may mimic that of inner ear disease. lethodology: This report presents two patients with cerebellar artery infarction initially misdiagnosed with inner ear lisease. ase Report: Both the patients presented with sudden hearing loss and vertigo. The patient in case 1 was initially liagnosed with idiopathic sudden sensorineural hearing loss. The patient in case 2 presented with 17 days of vertigo and iearing loss. Both were correctly diagnosed with AICA infarction after performing magnetic resonance imaging. esults and Conclusions: We differentiated AICA from inner ear disease based on the variability in degree and frequency ange of hearing loss, the duration of vertigo, and the manifestation of nystagmus. Because cases of AICA infarction and nner ear disease may present with si'milar symptoms, a detailed examination including clinical course assessments, aboratory findings, and neurological imaging is essential for appropriate diagnosis and treatment.
