A Case of Prolonged Delayed Postdural Puncture Headache in a Patient with Multiple Sclerosis Exacerbated by Air Travel
Figure 1
R: imaging demonstrates periventricular high signal intensity lesions, which exhibit a typical distribution for multiple sclerosis (Dawson's fingers). A: it shows corpus callosal hyperintensities suggestive of a demyelinating process. Patient does not have evidence of brain stem sagging, dilatation of vein or dural sinuses, and effacement of hemispheric cortical sulci. Absence of any of these signs does not preclude the diagnosis of postdural puncture headache.
