"The Up and Down Approach" to Localize and Exclude Sites of Intraspinal CSF Leaks

Myelography is a commonly performed procedure to locate cerebrospinal fluid (CSF) leaks in patients with spontaneous intracranial hypotension. Often, the site of leak within the spinal canal cannot be located creating a diagnostic dilemma for clinicians. This technical report describes a novel method to locate and exclude intraspinal CSF leaks in patients with multiple potential sites of CSF leak using a lumbar and cervical approach to inject intrathecal contrast and subse-quently performing CT myelography.(c) 2022 Elsevier Inc.
