Spontaneous CSF Leaks

Endoscopic Management of Spontaneous Clival Cerebrospinal Fluid Leaks: Case Series and Literature Review

“…Multiple studies have identified ICH as a negative risk factor for successful repair 2,25,26 . Obese, middle-aged women represent a high-risk group in terms of the development of both ICH and spontaneous CSF-L; in these patients, an increased ICP, caused by increased abdominal and thoracic pressures, leads to intracranial venous congestion and benign ICH 18,27,28 .…”

MR Myelography for Identification of Spinal CSF Leak in Spontaneous Intracranial Hypotension

“…7 CT myelography (CTM) has historically been considered the study of choice for the detection and localization of CSF leak, though a criterion standard test is difficult to establish, given the varied etiologies for SIH. 8 Recent literature has questioned whether CTM is the most sensitive technique for the detection and localization of CSF leaks. 9,10 More recent techniques have been described, including dynamic CTM, digital subtraction myelography, heavily T2-weighted spinal MR imaging, and intrathecal gadolinium MR myelography (MRM).…”

Endoscopic Management of Cerebrospinal Fluid Rhinorrhea: The Charing Cross Experience

“…39,40 The revision cases share similarities, namely spontaneous leaks are more difficult to manage and have lower success rates, with these patients typically being obese, middle-aged women with defects in pneumatized sphenoid lateral recesses. 4,19,20,23 Our other three failures belonged to this group and had successful revisions, with two being sphenoid and the other a posterior ethmoid roof defect.…”
