BACKGROUND AND PURPOSE: Posterior reversible @entity75 syndrome is a clinicoradiologic syndrome. Literature regarding associated factors and the prognostic significance of contrast enhancement in posterior reversible @entity75 syndrome is sparse. This study set out to evaluate an association between the presence of enhancement in posterior reversible @entity75 syndrome and various clinical factors in a large series of @entity1 with this syndrome. MATERIALS AND METHODS: From an MR imaging report search that yielded 176 @entity1 with clinically confirmed posterior reversible @entity75 syndrome between 1997 and 2014, we identified 135 @entity1 who had received @entity2287 -based contrast. The presenting symptoms, etiology, clinical follow-up, and maximum @entity551 within 1 day of MR imaging were recorded. MRIs were reviewed for @entity548 , MR imaging severity, and the presence and pattern of contrast enhancement. Statistical analyses evaluated a correlation between any clinical features and the presence or pattern of enhancement. RESULTS: Of 135 included @entity1 (67.4% females; age range, 7-82 years), 59 (43.7%) had contrast enhancement on T1-weighted MR imaging, the most common pattern being leptomeningeal (n = 24, 17.8%) or leptomeningeal plus cortical (n = 21, 15.6%). Clinical outcomes were available in 96 @entity1 . No significant association was found between the presence or pattern of enhancement and any of the variables, including sex, age, symptom, MR imaging severity, blood pressure, or outcome (all P > .05 after Bonferroni correction). CONCLUSIONS: The presence or pattern of enhancement in posterior reversible @entity75 syndrome is not associated with any of the tested variables. However, an association was found between MR imaging severity and clinical outcome.
