Cervical MR Imaging in Postural Headache: MR Signs and Pathophysiological Implications AJNR 22:1239-1250,1233, Yousry,I.,et al, 2001 See this aricle in Pubmed Article Abstract The MR signs of dilatation of the venous plexus, presence of spinal hygromas, and presence of retrospinal fluid collections can help to establish the diagnosis of intracranial hypotension. They are probably the result of decreased CSF volum e, with the retrospinal fluid collections being a trasudate from the venous plexus rather than frank extravasation. Resolution of these signs parallels resolution of the headache.
