BILATERAL ANTERIOR INFERIOR CEREBELLAR INFARCTION PRESENTING SEVERE VERTIGO AND HEARING LOSS

Anterior inferior cerebellar (AICA) infarctions are rarely seen, and bilateral AICA infarctions are mostly seen in the literature as case reports. Herein, a rare case with bilateral AICA infarction with severe vertigo, nausea and vomiting is presented. A sixty-nine-year-old woman was seen with the complaints of vertigo, tinnitus,nause, vomiting and hearing loss. In neurological examination, a dysarthric speech, horizontal nystagmus, bilateral peripheral facial palsy, right trigeminal hypoesthesia and mild ataxia were also noted. Mild sensorineural hearing loss (%30) was detected in the left ear through audiogram examination. In cranial MR imaging, a bilateral AICA infarction was reported. In addition, there were also bilateral hypoplastic posterior cerebral artery (PCA) and basilar artery stenosis in cranial MR angiography. The sympomts were partially disappeared following anti-platelet treatment. As in this case, in a patient with vertigo, AICA infarct should be kept in mind and detailed neurological examination should be performed.
