Objective To explore the clinical characteristics,imaging findings,and treatment methods of intracranial pure arterial malformations(PAMs).Methods A retrospective analysis was conducted on a typical patient with bilateral anterior cerebral artery(AC A)of intracranial PAMs admitted to the neurosurgery department of our hospital.Imaging data and clinical manifestations from years of follow-up were used to report and review the literature,in order to provide a basis for the diagnosis and treatment of intracranial simple arterial malformation.Results Cerebral angiography showed abnormal tortuous,dilated,and coiled arterial rings in the A2 segment of the bilateral AC A,and no clear signs of venous drainage were observed during the venous phase.Therefore,symptomatic pain relief treatment was given and patients were discharged.Conclusions For patients with ruptured bleeding,compression effects caused by intracranial PAMs(obstructive hydrocephalus,cranial nerve paralysis),and blood flow related aneurysms,active surgical intervention should be taken in clinical practice.For simple arterial malformations without these characteristics,regular imaging and clinical follow-up should be chosen as conservative treatment strategies.
