“…A case of duplication of a unilateral cerebellar hemisphere associated with a complex ipsilateral ear anomaly was reported by Jackson et al [7]. Another reported anomaly of cerebellum was a case of supernumerary hemi-cerebellum in an adult female patient who presented with headaches and episodes of syncope was reported by Hattapoğlu et al [8].…”

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.

“…In 1990, Jackson et al reported a case of duplication of a unilateral cerebellar hemisphere associated with a complex ipsilateral ear anomaly. 17 The author traced the timing of the problem to the third week of gestation. Clinically, patient's examination was significant to lower extremities hyper-reflexia, truncal hypotonia wide-base gait with right upper limb intentional tremors.…”

“…However, in regard to the discussed three reported cases of extracerebellar tissue, no specific genetic alterations or dedicated genetic testing was reported. 3,17,18 Jackson et al examined their patients and showed normal male chromosomes 46 XY. 17…”
