Abstract
The superior cerebellar artery (SCA) is a vessel anterior to the brainstem, usually originating from the basilar artery (BA). In this case, a different course of left SCA in a 74-year-old male cadaver was reported. The origin of the SCA was found to be a unilateral double root at the left side on the anterior surface of the pons. The distances of the starting points of roots to the bifurcation of BA were 31.09 mm on the right side, on the left side the rostral root was 33.84 mm and the caudal root was 30.95 mm. The diameter of the right SCA was 2.37 mm, the left rostral root was 2.05 mm and the caudal root was 1.24 mm. Knowing the course of SCA, and especially morphological variations, will be helpful for the clinical branches in preventing complications during surgical operations, evaluating angiographic examinations, and diagnosing and treating neurovascular diseases.
