A rare additional lobe of cerebellum, projecting from its superior surface

Abstract

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.

Cerebellar Hemangioblastomas in a High-risk Pregnancy: A Case Report and Review of Literature

“…In cerebellar hemangioblastomas, ataxia, discoordination, and increased intracranial pressure were often presented [ 8 ]. The lesions that occurred in the cerebellum were usually multifocal and cystic, accompanied by some solid nodular that were inserted into the cystic wall [ 9 , 10 ]. Severe symptoms caused by tumors were considered to be secondary to changes in peripheral tissue pressure or bleeding, mainly including headache, dizziness, vomiting, abnormal behavior, and epilepsy [ 11 , 12 ].…”
