Intracranial Cisternal Lipoma Associated with Cerebellar Cortical Dyspla-sia Diagnosed Using Dixon Technique: A Case Report and a Review of Literature

Abstract

Background: Intracranial lipomas are very rare congenital malformations. Previous studies have shown various brain anomalies related to intracranial lipomas, most of which are agen-esis or dysgenesis of the adjacent structures. To the best of our knowledge, cortical dysplasia relat-ed to intracranial lipoma has yet to be reported. Case Report: We present a rare case of intracranial lipoma in the quadrigeminal and superior cere-bellar cisterns with combined cerebellar cortical dysplasia. A 43-year-old female underwent brain MRI to identify possible cause of headache. We made a confident diagnosis based on MR findings using Dixon technique, which is a fat-water separation method based on chemical shift. We also identified unique combined abnormalities of the right cerebellar hemisphere near the cisternal lipo-ma that showed an abnormal vertical orientation of the cerebellar folia and disorganized parenchy-mal pattern. Conclusion: This case exhibits the rareness of the intracranial lipoma related cerebellar cortical dysplasia by reviewing relevant literature and also highlights the usefulness of Dixon techniques in daily clinical practice.
