Anterior Inferior cerebellar artery infarction misdiagnosed as inner ear disease.
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.
小脑前下动脉梗死误诊为内耳疾病。
小脑前下动脉（AICA）梗死的临床表现可能与内耳疾病相似。
本报告介绍了两名最初被误诊为内耳疾病的小脑动脉梗死患者。
两名患者均表现为突发听力损失和眩晕。病例1的患者最初被诊断为特发性突发性感音神经性听力损失。病例2的患者出现眩晕和听力损失17天。在进行磁共振成像后，两人均被正确诊断为AICA梗死。
我们根据听力损失的程度和频率范围的变异性、眩晕的持续时间以及眼球震颤的表现，将AICA梗死与内耳疾病区分开来。由于AICA梗死和内耳疾病的病例可能表现出相似的症状，因此包括临床病程评估、实验室检查结果和神经影像学检查在内的详细检查对于正确的诊断和治疗至关重要。
