Human cerebellum plays a vital role in motor coordination, regulation of muscle tone and maintaining the equilibrium of the body. It seldom shows anatomical/morphological variations. Herein, we report the presence of a small additional lobe projecting out on the superior surface of the right cerebellar hemisphere in the para-vermal area in an adult male cadaver. There was a notch on the tentorial surface of the occipital lobe of the right cerebral hemisphere, corresponding to the additional lobe of cerebellum. The additional lobe was histologically normal, with no evidence of any tumour cells. Knowledge of this variation is of importance to radiologists, neuroanatomists and neurosurgeons.
人类小脑在运动协调、肌肉张力调节和维持身体平衡方面起着至关重要的作用。它很少出现解剖学/形态学变异。在此，我们报告在一名成年男性尸体的右侧小脑半球上表面近蚓部区域出现一个额外的小叶片。右侧大脑半球枕叶的小脑幕表面有一个切迹，与小脑的额外叶片相对应。额外叶片在组织学上是正常的，没有任何肿瘤细胞的迹象。了解这种变异对放射科医生、神经解剖学家和神经外科医生很重要。
