ABSTRACT
Objective To investigate the computer tomography (CT) and magnetic res-onance imaging (MRI) features of posterior reversible encephalopathy syndrome (PRES) caused by pregnancy-indueed hypertension (PIH). Methods CT scan and MRI scan + diffusion-weighted imaging (DWI) were used in 31 patients with PIH. Results CT scan found low density lesions in parietal-occipital lobe of watershed regions in 31 patients with PIH. CT value was 19 to 23Hu. Among them, MRI showed slight hypointensity lesions on T1-weighted images and slight hyperintensity lesions on T2-weight images in 11 patients, fluid-attenuated inversion recovery (FLAIR) sequence showed hyperintensity lesions, DWI revealed isointense, and apparent diffusion coefficient- did not decrease. The recovery time of clinical symptoms was earlier than that of MRI. Conclusions The lesion sites on cr and MRI had certain characteristics in PIH occurred PRES at late pregnancy, combining clinical history a clear diagnosis could be made.
ABSTRACT
Objective To investigate the relationship between cerebrospinal fluid (CSF) changes and prognosis in patients with neurosyphilis.Methods The CSF and the clinical data of 55 syphilis patients were analysed retrospectively,including 30 neurosyphilis cases and 25 syphilis cases during incubation period.The CSF leukocyte, protein and pressure of the two groups were measured,meanwhile, rapid plasma regain circle card(RPR) and treponema pallidum particle assay (TPPA) were simultaneous determination. All cases were treated with penicillin G normally during the whole range.Two groups of patients were followed-up by telephones or outpatient department in two year and the prognosis were evaluated. Function Independent Measure (FIM) were scored at the same time.Results The seum RPR and TPPR in two group patients were all positivity CSF leukocyte and protein were higher in neurosyphilis than that of in syphilis incubation period, There was significant difference between the two groups (all P
