Infarctions in the medial PICA territories and discuss the possibleĬauses of such a presentation. Only few such cases are reported in literature soįar.1-4 Here we report a lady who presented with bilateral cerebellar Simultaneous cerebellar infarctions in the medial PICA territories areĮxtremely rare. The origin of PICA arises from a single vertebral artery (VA). Inferior cerebellar artery (PICA) are rare. Strokes in the distribution of the posterior Generally have a good prognosis considering the very small area of blood We also list out the possible mechanisms ofīilateral medial PICA territory infarction. Supply along with the clinical features differentiating the medial and We discuss the anatomical peculiarities of PICA and its blood She was aĭiabetic and had features of diffuse atherosclerotic vertebrobasilarĭisease. We report one such patient who presented with acute bilateralĬerebellar infarctions in the medial PICA territories. Sudden simultaneousĬerebellar infarctions in the medial PICA territories are extremely Lateral division or the medial division of PICA. From the results of the present study, it is evident that there was a significant PICA emergence from the superior part of the vertebral artery and that the double origin of non-hypoplastic trunks was also found in some patients the latter is associated with a greater chance of aneurysms and other additional complications.Strokes involving posterior inferior cerebellar arteries The clinical implication of this knowledge and consensus is obtaining the best surgical strategies for clipping aneurysms and, in addition, the best choices for occlusion of the vessel affected if the territory of the main vessel has an adequate collateral circulation. CONCLUSION: The results obtained in the present study indicated the great importance of the studies and reviews on the different topographies of PICA these studies and reviews expand the knowledge and consensus on the characteristics and implications of PICA's variations. The double origins of non-hypoplastic PICAs were found in 17% (n = 4) of patients. Moreover, variations such as hypoplastic arteries, missing trunks on one side and double or triple trunks, different emergence sites, significant PICA emergence from the superior part of the vertebral artery (59% of the trunks), and asymmetries between the right and left sides were recorded. RESULTS: Some striking variations were found, such as the absence of the left vertebral artery in one of the brains and the emergence of any PICA in another two brains studied. MATERIAL and METHODS: The present study analyzed the different variations of the PICA's first two segments, the anterior medullary and lateral medullary segments, regarding the number of trunks, their emergency site, and the presence or absence of hypoplasia of this artery, through microsurgical dissection of 23 fresh cadaver brains.
