Neuroimaging Features of Ectopic Cerebellar Tissue: A Case Series Study of a Rare Entity

Neuroimaging Features of Ectopic Cerebellar Tissue: A Case Series Study of a Rare Entity Published April 1, 2021 as 10.3174/ajnr.A7105 CLINICAL REPORT PEDIATRICS Neuroimaging Features of Ectopic Cerebellar Tissue: A Case Series Study of a Rare Entity G. Orman, S.F. Kralik, R. Battini, B. Buchignani, N.K. Desai, R. Goetti, A. Meoded, C. Mitter, B. Wallacher-Scholz, E. Boltshauser, and T.A.G.M. Huisman ABSTRACT SUMMARY: Ectopic cerebellar tissue is a rare entity likely secondary to multiple, interacting, developmental errors during embryo- genesis. Multiple sites of ectopic cerebellar tissue have been reported, including extracranial locations; however, an intracranial location is most common. We report on the MR imaging findings of a multi-institutional series of 7 ectopic cerebellar tissue cases (2 males, 4 females, 1 fetal) ranging from 22 weeks 5 days’ gestational age to 18 years of age. All cases of ectopic cerebellar tissue were diagnosed incidentally, while imaging was performed for other causes. Ectopic cerebellar tissue was infratentorial in 6/7 patients and supratentorial in 1/7 patients. All infratentorial ectopic cerebellar tissue was connected with the brain stem or cerebel- lum. MR imaging signal intensity was identical to the cerebellar gray and white matter signal intensity on all MR imaging sequences in all cases. Ectopic cerebellar tissue should be considered in the differential diagnoses of extra-axial masses http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png American Journal of Neuroradiology American Journal of Neuroradiology
