Table 1 Showing comparative literature review
Authors | Year of study | Methods | Findings | Conclusion |
|---|---|---|---|---|
Soto-Ares et al. [1] | 2000 | In this study, there was a retrospective review of 46 MR examinations of patients presenting with developmental delay, hypotonia, and facial deformities to identify abnormal folia or fissures or both within cerebellar hemispheres or vermis suggesting cortical dysplasia | This study diagnosed cerebellar dysplasia in 17 patients, but it was isolated in only two patients | This study could conclude that cerebellar cortical dysplasias are common in cases with more widespread cerebral malformations |
Baek [3] | 2013 | Case report | This report describes a case of isolated unilateral cerebellar cortical dysplasia with partial agenesis of corpus callosum. Foliation of contralateral cerebellar hemisphere and other structures in the posterior fossa were normal | It was suggested by the author that awareness of cerebellar cortical dysplasia and its embryologic background can be helpful for recognition of this mild form of cerebellar abnormality on high-quality MR imaging in clinical practices |
Patel and Barkovich [6] | 2002 | MR images obtained in 70 patients with cerebellar malformations were retrospectively reviewed | In this study, non-syndromic (isolated) focal cerebellar dysplasia was seen in only two patients, while isolated cerebellar hypoplasia was diagnosed in six patients | This study proposed a scheme to organize cerebellar malformations |
Chatur et al. [8] | 2019 | Case report | This is a case report of isolated cerebellar dysplasia in which, MRI brain revealed hemihypertrophy of left cerebellar hemisphere with disorganized architecture, fissural malorientation with individual folia running vertically rather than horizontally with disorganized foliation, abnormal arborization of white matter. Right cerebellar hemisphere and cerebellar vermis were normal. Cerebral parenchyma and Corpus callosum were normal | It was deduced by the authors that understanding of the basics of cerebellar embryology, knowledge of the imaging features, and clinical presentation aids in the precise diagnosis of this disorder and its optimal management |
Babal and Aggarwal [This case report] | 2023 | Case report | Isolated cerebellar dysplasias with no other structural or signal abnormality in the rest of the brain | Notable isolated unilateral cerebellar dysplasia is a rare entity requiring symptomatic treatment and anomalous developmental process being the likely aetiology |
