RESUMO
Objective To evaluate the clinical application of enhancement scan and angiography of dual-source computed tomography (CT) in purulent meningitis.Methods The clinical data,imaging data of enhancement scan and angiography of dual-source CT of 8 cases with purulent meningitis were analyzed retrospectively.Results There was linear or bead-like high intensity enhancement of different degree around the cistern,groove or the cerebral vessels in 6 cases,especially around the basal cistern and ambient cistern; a ring-like enhancement was shown in the temporal lobe in 1 case; fusiform change of the cerebral arteries was shown in angiography of dual-source CT in 2 cases.Conclusion Enhancement scan and angiography of dual-source CT is valuable for early diagnosis of purulent meningitis and improve the diagnosis rate.
