T appropriate management of adults with filum lipoma (FL) with normal neurological status remains unclear.1,2 Factors such as younger age at presentation, low-lying conus medullaris (CM), thick FL, and the proximity of fat to the CM has not been consistent in the literature in predicting the development of neurological deficits.1-3 The objective of the present study was to evaluate radiological...

Abstract Approximately 125 years ago, a group of pathologies now known as Chiari malformations was described for the first time. However, some mechanisms its formation still remain unknown.

HBs of the lower spinal region are highly vascular tumors requiring surgery that is potentially complicated by excess...
