Cerebral miliary micro aneurysms in polyarteritis nodosa : Report of two cases

摘要

Cerebral involvement is rare in polyarteritis nodosa (PAN) and is mostly characterized by ischemic events and intracranial hemorrhages secondary to cerebral aneurysms is extremely rare. We report two patients of PAN with multiple intracranial aneurysms. One patient presented with intracerebral hemorrhage and in the other patient multiple intracranial aneurysms were incidental findings and were asymptomatic. Both our cases suggest that multiple intracranial aneurysms are not very uncommon in PAN and cerebral angiography should be considered while doing abdominal angiogram in these patients.
