“…3 CT of the head also may provide information about associated intracranial haematomas or injury to the neural structures. 1,[7][8][9] The forces resulting in traumatic atlanto-occipital dislocation is of high-energy acceleration/decceleration type that overcome the muscular and ligamentous attachments of the craniocervical junction. 2,9 The fatal outcome is usually caused by mechanical damage to upper brainstem or spinal cord.…”

“…Basal brain arteries are known to be easily ruptured secondary to relatively minor blunt trauma [8], through to strain mechanisms [9], sometimes associated with alcohol abuse [10]. For example Mant described a series of eight lethal traumatic subarachnoid hemorrhages secondary to apparently minor trauma to the head or neck [9].…”

The anatomy of the posterior inferior cerebellar artery (PICA) has a wider variability compared to the superior cerebellar artery (SCA) or the anterior inferior cerebellar artery (AICA). The PICA with bihemispheric distribution (bPICA) can be found in less than 0.1% of cases. We report here a rare such case, documented by anatomical microdissection. A true right bPICA was found emerging the origin of the basilar artery. From its lateral medullary segment the equivalent of the rostral trunk of an AICA was leaving, and from the tonsillomedullary segment of the bPICA emerged a trunk distributed in the territory of the caudal branch of the AICA. The telovelotonsilar segment of that bPICA was further sending off the PICAs proper, ipsilateral and contralateral. Each of these was supplying equally the vermis and the cerebellar hemisphere. The contralateral PICA proper was also distributed in the territory of the caudal trunk of the AICA, while the rostral trunk of the absent AICA was supplied by the SCA. Radiologists and surgeons should be aware of this variant, to diagnose it accurately, avoid pitfalls in diagnosis of bilateral cerebellar infarcts, and to avoid its damage during the microsurgical exposures.

“…13 Traumatic aneurysms or rupture of the posterior inferior cerebellar artery have been described with blunt head injury in several case reports or small case series. [14][15][16][17] Purgina et al obtained autopsy in their case and showed that blunt trauma had caused a posterior inferior cerebellar artery (PICA) pseudoaneurysm with no arterial walls. 14 They proposed that acceleration and deceleration of the cerebellum caused a PICA aneurysm at the origin.…”
