Abstract:
Objective To discuss the MRI characteristics of pituitary abscess,so that to improve the diagnosis of it.Methods MR imaging data in 8 cases with pituitary abscess proved by operation and pathology,and antibiosis therapy were retrospectively analyzed in combination with review of literatures.Of 8 cases,3 were male and 5 were female,the mean age was 53.3 years(ranged 36~62 years).Results MRI findings included hypophysis enlargement,isointensity in 6 cases and slight hyperintensity in 2 cases on T1WI;isointensity in 4,hyperintensity in 2 and mixed iso-and hyperintensity in 2 on T2WI;hyperintensity in one on DWI.On contrast-enhanced scan,all pituitary masses showed ring enchancement,6 cases showed thickened walls which were slightly lamellar;7 cases demonstrated pituitary stalk thickening and enchancement.Conclusion Pituitary abscesses are of certain typical MRI characteristics.
