Objective The objective of this report is to compare computed tomography (CT) and magnetic resonance (MR) myelography with radioisotope cisternography (RC) for detection of spinal cerebrospinal (CSF) leaks. Methods We retrospectively reviewed 12 spontaneous intracranial hypotension (SIH) patients; CT and RC were performed simultaneously. Three patients had MR myelography. Results CT and/or MR myelography identified CSF leaks in four of 12 patients. RC detected spinal leaks in all three patients confirmed by CT myelography; RC identified the CSF leak location in two of three cases, and these were due to osteophytic spicules and/or discs. RC showed only enlarged perineural activity. Only intrathecal gadolinium MR myelography clearly identified a slow leak from a perineural cyst. In eight remaining cases, the leak site was unknown; however, two of these showed indirect signs of CSF leak on RC. CSF slow leaks from perineural cysts were the most common presumed etiology; and the cysts were best visualized on myelography. Conclusion RC is comparable to CT myelography but has spatial limitations and should be limited to atypical cases.

Our previous study demonstrated that heavily T2-weighted magnetic resonance (MR) myelography could successfully detect abnormal cerebrospinal fluid (CSF) collections in patients with spontaneous intracranial hypotension (SIH); however, its ability to demonstrate ongoing CSF leakage sites is uncertain. Currently, computed tomographic (CT) myelography is still considered the study of choice for such a purpose. In this study, we compared the results of the two imaging modalities in two patients with SIH. CSF leakages, such as C1-2 extraspinal collections, CSF along nerve root sleeves, and epidural fluid collections were noted on both studies with minor discrepancies. CSF collection along nerve root sleeves demonstrated by MR myelography was the most likely ongoing leakage site in comparison with CT myelography. Targeted epidural blood patches in both patients resulted in complete headache resolution. Noninvasive, non-contrasted and time-saving MR myelography is a promising study for patients with SIH. Further large-scale validation studies are needed.

✓ The authors describe a case of spontaneous intracranial hypotension in which the leakage site was determined by using magnetic resonance (MR) myelography. This technique demonstrated the route of cerebrospinal fluid (CSF) leakage, whereas other methods failed to show direct evidence of leakage. Magnetic resonance myelography is a noninvasive method that is highly sensitive in detecting CSF leakage. This is the first report in which a site of CSF leakage was detected using MR myelography.

A literature search found no clinical trials or guidelines addressing the management of spontaneous intracranial hypotension (SIH). Based on the available literature and expert opinion, we have developed recommendations for the diagnosis and management of SIH. For typical cases, we recommend brain magnetic resonance (MR) imaging with gadolinium to confirm the diagnosis, and conservative measures for up to two weeks. If the patient remains symptomatic, up to three non-directed lumbar epidural blood patches (EBPs) should be considered. If these are unsuccessful, non-invasive MR myelography, radionuclide cisternography, MR myelography with intrathecal gadolinium, or computed tomography with myelography should be used to localize the leak. If the leak is localized, directed EPBs should be considered, followed by fibrin sealant or neurosurgery if necessary. Clinically atypical cases with normal brain MR imaging should be investigated to localize the leak. Directed EBPs can be used if the leak is localized; non-directed EBPs should be used only if there are indirect signs of SIH.
