The incidence of anterior inferior cerebellar artery infarction in acute stroke is only 0.9% and represents 5.2% of patients affected the vertebrobasilar territory. Infarction of the MCP is a rare type of AICA syndrome. The presence of vertigo, ataxia, peripheral facial palsy and ipsilateral hypoacusia means a “complete AICA infarct”.1 Patients with infarction localized in the bilateral middle cerebellar peduncles were rare.1 Adams1 noted rotational dizziness, vomiting, tinnitus and dysarthria on the side of the infarction as well as dysmetria, facial palsy, trigeminal sensory impairment, Horner syndrome and loss of pain and temperature on the opposite side.2 The clinical picture described by Adams1 was called the classic AICA syndrome. Application of stent at the site of stenosis can significantly improve the symptoms in 2 patients. The treatment consisted mainly of anticoagulation, antiplatelet therapy. Separate AICA infarction can be considered in cases 2, 3 and 4. We observed an infarct in the SCA area in case 1. Image analysis of 4 cases demonstrated that the infarction lesion was located in the middle cerebellar peduncles and other AICA supply area with or without PICA or involvement of SCA supply area.
