Subdural fluid collection rather than meningitis contributes to hydrocephalus after cervical laminoplasty: A case report

Figure 1 Previous imaging data at a local hospital. A: Sagittal T2-weighted cervical magnetic resonance (MR) image before laminoplasty surgery revealing cervical spinal stenosis; B: Axial T2-weighted MR image before laminoplasty surgery showing a normal ventricle; C and D: Sagittal T2-weighted MR image showing obvious cerebrospinal fluid leakage without subdural fluid collection at 1 and 8 mo after cervical laminoplasty; E: Cervical MR image at 9 mo after laminoplasty surgery demonstrating a cystic lesion around the cervical spinal cord and medulla oblongata; F: Head computed tomography scan at 9 mo after cervical laminoplasty revealed hydrocephalus with marked enlargement of the ventricular system without any occupying lesion.
