[Extraordinary high cerebrospinal fluid protein in two cases of intracranial hypotension syndrome].
Intracranial hypotension is a rare cause of chronic headache. Although there is still debate about the aetiology, it is believed that the syndrome is caused by low cerebrospinal fluid volumes due to dural leakage. Such leakages can occur spontaneously after lumbar puncture or surgical or traumatic opening of the dura. In magnetic resonance contrast imaging, diffuse meningeal enhancement can be seen; usually the pressure at the cerebrospinal opening is lower than normal. Sometimes a pleocytosis and, in most cases, increased protein content can be identified in the CSF. These protein levels most frequently range between 0.5 g/l and 2 g/l. Here we describe two patients with typical clinical signs and neuroradiological alterations of intracranial hypotension syndrome but with extraordinarily high CSF protein levels (8.3 g/l and 9.63 g/l). On the basis of these findings, the putative causes of elevated CSF protein contents are discussed.
