Intracranial Hypotension: The Nonspecific Nature of MRI Findings


Address all correspondence to Dr. Osvaldo Bruera, Pringles 760 1° 6, (1183), Buenos Aires, Argentina.


We present three patients who complained of postural headache related to different types of intracranial hypotension: spontaneous or primary, and secondary, but presenting the same findings on brain magnetic resonance imaging. Diffuse pachymeningeal gadolinium enhancement supports the belief that the enhancement is a nonspecific meningeal reaction to low pressure.
