Spontaneous intracranial hypotension (SIH) is most commonly caused by spinal CSF leaks, with ventral dural defects frequently requiring surgical repair when conservative measures fail. Endoscopic transforaminal approaches have emerged as minimally invasive alternatives to traditional open techniques, but the physiological consequences of …

BACKGROUND AND OBJECTIVES: Spontaneous spinal CSF leaks cause intracranial hypotension (SIH) and may be complicated by bibrachial amyotrophy (BBA), but the clinical and radiographic features of this complication are not well characterized. The objective of this study was to identify the unique …

BACKGROUND AND PURPOSE: Spontaneous spinal CSF leaks cause spontaneous intracranial hypotension (SIH) and several types have been identified. One rare type is the dorsal CSF leak and performing myelography in the supine or lateral decubitus position allows precise characterization of these leaks. …

CSF-venous fistulas are an increasingly recognized cause of spontaneous intracranial hypotension. Most CSF-venous fistulas arise from meningeal diverticula along the nerve root sleeves. Therefore, the presence of diverticula on spine MRI may serve as an important predictor for the presence of a …

Background Spontaneous spinal CSF leaks are associated with connective tissue diseases including Marfan syndrome and Loeys–Dietz syndrome, which are caused by mutations in genes that influence the content and integrity of the extracellular matrix. Patients with spontaneous spinal CSF leaks without a …

BACKGROUND AND PURPOSE: Spontaneous spinal CSF-venous fistulas were first described in 2014 and much remains unknown about this common cause of intracranial hypotension, including their basic pathophysiology. One point of contention is whether there is 1-way or 2-way flow through these fistulas. …

BACKGROUND AND PURPOSE: Genetic factors often are implicated in the etiology and pathogenesis of spontaneous spinal CSF leaks. Nevertheless, the familial occurrence of spontaneous intracranial hypotension (SIH) and the prevalence of heritable connective tissue disorders (hCTDs) have never been studied in large …

BACKGROUND AND PURPOSE: Intracranial hypotension-arising from CSF leaks that are iatrogenic, traumatic, or spontaneous-is a potentially debilitating condition resulting in orthostatic headaches and other neurologic symptoms. While pediatric CSF leaks are challenging to manage due to limited data, digital subtraction myelography (DSM) …

BACKGROUND AND PURPOSE: Some patients with spontaneous intracranial hypotension (SIH) continue to have symptoms despite radiographic resolution of their spinal CSF leak. The purpose of the present study is to report the indications, intraoperative findings, and outcomes of exploratory surgery of radiographically …

BACKGROUND AND PURPOSE: Sacral dural tears are an underrecognized cause of spontaneous intracranial hypotension, and their clinical behavior and response to treatment remain incompletely defined. We hypothesized that outcomes following epidural patching in sacral dural tears are driven primarily by disease chronicity …
