Prominent Meckel caves without frank meningoceles were found in 9% of IIH patients versus 0% of control subjects (p < 0.003). CSF is a clear fluid that cushions the brain and spinal cord. It should be suspected if the collection thickness is wider than 6 mm, shows higher T2 fluid-attenuated inversion recovery (FLAIR) signal as compared to cerebrospinal fluid (CSF), and displays hemorrhagic staining on T2*GRE. The vast majority of cysts dont need further treatment.
