Paraganglioma of the cauda equina region--report of two cases and review of the literature.

abstract：BACKGROUND:Although the majority of patients with minimal acute subdural hematomas (aSDHs) can be managed conservatively, some require delayed aSDH evacuation due to hematoma enlargement. This study was designed to determine the risk factors associated with delayed hematoma enlargement leading to surgery in patients wi...
