Vermian dysplasia and lipoma in a child with headache and epileptic seizure

Objectives: Describing the MRI features of cerebellar dysplasia and lipoma in a child with epilepsi. Methods: A nine year old boy who has been treated for headache at our pediatric neurology dapartment had a severe seizure during his follow-up. His family descripted the seizure as 'falling on his back with unconsciousness' . The birth history was unremarkable. Family history revealed no known consanguinity. General examination revealed no dysmorphic features. Neurological examination revealed no cognitive deficits/signs to suggest cerebellar pathology. We obtained a cranial MRI which showed us that superior part of the cerebellar vermis is dysplastic and had fat signal consistant with lipoma. Results: Cerebellar malformations are a rare group of disorders with clinical heterogeneity. The congenital malformations affecting the cerebellar parenchyma are very rare. Conclusion: We describe a case of 9 years old boy with cerebellar hypoplasia accompanying a lipoma who had a severe epileptic seizure while being treated for headache, with emphasis on the MRI features of this rare entity.
