Multistage CSDH can be diagnosed by brain computed tomography (CT). However, diagnosing multistage and “multiseptated” CSDH using only a brain CT scan may be difficult. Magnetic resonance imaging (MRI) may provide helpful information for diagnosing multiseptated CSDH.2) Lee et al.4) reported that diffusion-weighted MRI provides better resolution of multiseptated CSDH and can predict post-treatment failure more accurately than brain CT.
