MR Imaging Features of Pyocephalus / 实用放射学杂志

ABSTRACT

Objective To analyze the MR imaging features of pyocephalus. Methods MR imaging features!of pyocephalus in 5 cases with clinically proved were analyzed retrospectively. All patients were undergone no-contrast MR imaging. 3 patients received diffusion weighted-imaging(DWI). Results In all five patients,the debris and pus with pus-fluid level were shown inside the lateral ventricle.The debris or pus was slightly hyperintense on T1WI, slightly hypointense on T2WI relative to cerebrospinal fulid(CSF). On DWI, the debris was hyperintense in 1 case and isointense in 2 cases.Conclusion The features of MR imaging of pyocephalus is specific. MR imaging is valuable in the diagnosis of pyocephalus.
