en General گزارش مورد case report <div style="text-align: justify;"><span style="font-size:14px;"><span style="font-family:Times New Roman;"><strong>Introduction: </strong>Anatomic variation in the circle of Willis (CoW) is a common finding among the population. Headache has been reported as one of the symptoms of these variations. Case Presentation: Recent studies suggest a possible association between neurovascular accidents and these variations. In this case, a 50-year-old male presenting with headache underwent imaging evaluation, revealing anatomic variations in CoW.<br> <strong>Conclusions: </strong>Headaches with or without neurological symptoms or a history of migraine and transient ischemic attack (TIA) may suggest the diagnosis of CoW disease and variations, and additional imaging evaluation is recommended in these cases.</span></span></div> Headache,Anatomic Variation,Transient Ischemic Attack,Circle of Willis 0 0 http://mcj.bums.ac.ir/browse.php?a_code=A-10-1-205&slc_lang=en&sid=1 Mersad Mehrnahad mersad.mehr@gmail.com 10031947532846005318 10031947532846005318 Yes Qom university of Medical Sciences, Qom, Iran Mahdi Hamzeh 10031947532846005319 10031947532846005319 No Department of Neurosurgery, School of Medicine, Arak University of Medical Sciences, Arak, Iran Mohammad Hasanian 10031947532846005320 10031947532846005320 No Department of Radiology, School of Medicine, Arak University of Medical Sciences, Arak, Iran
