Dr. Saniya Harish Lade ^[3] | Dr. Sonal Anand Talokar ^[2]

Abstract: Thomas Willis in 1962 described the anatomy of cerebral vessels and clearly recognized its functional significance. Considerable variation exist in circle of willis which are already studied and will be studied in this research also. This being important to neurosurgeons as variation may profound clinical implications.70 adult brains were studied out of which 53 are males and 17 are females. Hypoplasia of posterior cerebral artery and posterior communicating artery are observed. Frequency of adult configuration is higher i. e 62.85 %.10 % showed foetal configuration while 12.85 % of circles show transitional configuration in present study.
