“…Clinical pictures vary according to the infarction localization in the infarctions compatible with AICA irrigation area. Whereas symptoms such as isolated vertigo mimicking labyrinthitis or ataxia are present in partial AICA, bilateral AICA may follow a severe clinical course which ultimately can cause coma ( 6,7,8). In our case, although bilateral involvement was present, it was not that severe.…”

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.

“…Only six cases were reported in a study which documented 1350 cases with posterior system infarction (5). In another study it was reported that AICA formed 0.9% of all the cerebrovascular events and 5.2% of vertebrobasillar infarctions (6). Bilateral AICA infarctions are present only in the form of case reports in the literature.…”

“…The structures mainly damaged in these scenarios are the middle cerebellar peduncle and flocculus, with extension into the neighboring cerebellar lobules between the territories of the SCA and PICA. Roquer et al in 1998 54 presented a correlative study between neurological symptoms and findings on MRI in patients with AICA strokes using the anatomical diagrams of Amarenco and Hauw. 2 The middle cerebellar peduncle was the core of the affected territory in AICA strokes and was suggested as the radiological hallmark of this vascular insult.…”

T he surgical anatomy of the cerebellopontine angle (CPA) is complex and challenging. The cerebellopontine cistern (CPC) lies in the CPA between the brainstem, cerebellum, and petrous portion of the temporal bone and is crossed by multiple delicate nerves and small vessels directed toward the cerebellum and highly eloquent portions of the brainstem. This region often witnesses vascular pathology and tumors, leading to lengthy cerebellar retraction, dissection, and the use of bipolar coagulation that jeopardizes the integrity of cranial nerves (CNs) and cerebellar and brainstem perfusion. The cisternal surface of the middle cerebellar peduncle lateral to the cerebellar flocculus-namely, the paraflocculus or parafloccular perforating space-is particularly susceptible to the abovementioned surgical manipulation from a retrosigmoid approach, which is the workhorse approach for CPA lesions. The importance of this small but key area in the cerebellopontine interface was recognized in a classic article by David and Askenasy in the 1930s, 14 and previously published articles have described its topographic relationship to the major branches of the anterior inferior cerebellar artery (AICA) and posterior inferior cerebellar abbreviatioNs AICA = anterior inferior cerebellar artery; CN = cranial nerve; CPA = cerebellopontine angle; CPC = cerebellopontine cistern; PICA = posterior inferior cerebellar artery; SCA = superior cerebellar artery. obJective The cerebellopontine angle is a common site for tumor growth and vascular pathologies requiring surgical manipulations that jeopardize cranial nerve integrity and cerebellar and brainstem perfusion. To date, a detailed study of vessels perforating the cisternal surface of the middle cerebellar peduncle-namely, the paraflocculus or parafloccular perforating space-has yet to be published. In this report, the perforating vessels of the anterior inferior cerebellar artery (AICA) in the parafloccular space, or on the cisternal surface of the middle cerebellar peduncle, are described to elucidate their relevance pertaining to microsurgery and the different pathologies that occur at the cerebellopontine angle. methods Fourteen cadaveric cerebellopontine cisterns (CPCs) were studied. Anatomical dissections and analysis of the perforating arteries of the AICA and posterior inferior cerebellar artery at the parafloccular space were recorded using direct visualization by surgical microscope, optical histology, and scanning electron microscope. A comprehensive review of the English-language and Spanish-language literature was also performed, and findings related to anatomy, histology, physiology, neurology, neuroradiology, microsurgery, and endovascular surgery pertaining to the cerebellar flocculus or parafloccular spaces are summarized. results A total of 298 perforating arteries were found in the dissected specimens, with a minimum of 15 to a maximum of 26 vessels per parafloccular perforating space. The average outer diameter of the cisternal portion of the perforating arteries was 0.1...
