Аннотация: Modern neuroimaging methods do not completely rule out false diagnoses of intracranial aneurysms whichcan lead to an unwarranted operation associated with risks of complications. However, surgicalinterventions for falsely diagnosed aneurysms are quite rare. The purpose of this study is to demonstrate twoclinical cases of false-positive aneurysms and a systematic review of the literature dedicated to theincidence and etiology of false-positive aneurysms, identifying risk factors associated with false-positiveaneurysms. A literature search in two databases (PubMed and Web of Science) using keywords "mimickingan intracranial aneurysm", "presenting as an intracranial aneurysm", "false positive intracranial aneurysms",and "neurosurgery” was conducted. A total of 243 papers were found in the initial search in two databases.Sixteen papers (including 20 patients) were included in the final analysis. There were 10 women and 10 men.The most common location of false-positive aneurysms was the bifurcation of the middle cerebral artery(MCA). In the posterior circulation, false-positive aneurysms were identified either on the basilar artery, orat the vertebro-basilar junction. The main causes of false intracranial aneurysm diagnosis included arteryocclusion with vascular stump formation, infundibular widening, fenestration, arterial dissection, contrastextravasation, and venous varix. In conclusion, summarizing the results of our analysis, we can say thatsurgical interventions for false-positive aneurysms are an underestimated problem in vascular neurosurgery.Despite extremely rare published clinical observations, the actual frequency of erroneous surgicalinterventions for false-positive aneurysms is unknown.
