The role of diagnostic imaging for intracranial hypotension consists of definitive diagnosis of intracranial hypotension and detection of cerebral spinal fluid (CSF) leakage. Magnetic resonance imaging (MR) is the initial modality of choice for patients with symptoms suggesting intracranial hypotesion. Dural enhancement on postcontrast spin-echo T1-weighted imaging and subdural effusion on fluid attenuated inversion recovery are essential findings of the diagnostic criteria. MR myelography is a noninvasive method to detect CSF leakage; however, extradural hyperintensity on MR myelography is non-specific for CSF. Fat-saturated axial T2-weighted imaging and postcontrast axial T1-weighted imaging should be added to confirm CSF leakage.
