At postmortem, the wall of the fusiform proximal AICA aneurysm was infiltrated and almost completely destroyed by vital and necrotic adenocarcinoma masses (figure, C) with histologically proved ruptures as the cause of the recurrent subarachnoid haemorrhage. 1-3 In the opposite AICA, a developing neoplastic aneurysm was demonstrable with different stages of intramural tumour growth and destruction of the vessel wall (figure, D). 4 The proximal portion of the basilar artery was covered by an adenocarcinoma cell layer which had caused a thrombus in the left vertebral artery and was the reason for the initial PICA infarction.
