Traumatic vertebrobasilar pseudoaneurysms: diagnostic pitfalls on CT angiography with forensic implications — two case reports
Traumatic pseudoaneurysms of the vertebrobasilar artery are rare and may occur without skull fractures. Standard CTA may miss or misinterpret these lesions due to technical limitations and low clinical suspicion, leading to significant diagnostic and medicolegal errors; We present two cases of fatal isolated traumatic subarachnoid hemorrhage (iTSAH), where optimized thin-slice CTA, identified pseudoaneurysms of the PICA and VA (V4 segment), confirmed by histopathology.
