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

Figure 3 Cervical magnetic resonance imaging and brain computed tomography in follow-up period. A: Cervical magnetic resonance imaging at 2 d after dural repair showing significantly deceased pseudomeningocele and subdural fluid collection; B: Subdural fluid collection disappeared completely 15 mo after dural repair; C: Computed tomography-scan at 3 mo after dural repair demonstrated reduced hydrocephalus compared with pre-operation; D: Brain magnetic resonance at 1 year after dural repair showed that the ventricular system almost returned to normal shape.
