Abstract

Observations concerning the posterior inferior cerebellar artery (PICA) are mostly based on embryological studies, cadaveric dissections, surgical and angiographic evaluation [1–3]. The correlation between vascular occlusion and clinical implications as well as the evaluation of space-occupying brain lesions has encouraged numerous researches, thus exploring a scientific path of considerable interest [4]. This allowed embryologists, anatomists, neurosurgeons, neurologists and ultimately interventional neuroradiologists to carry out an extensive and in-depth research for the PICA. This phylogenic recent artery is one of the most complex and fascinating cerebral arteries with a high number of anatomical variations perhaps due to its late embryological development [5, 6]. In this chapter, we will develop each variation implicating the PICA after a little embryological remind and “normal anatomy” description.
