Abstract:
Objective To study MR imaging diagnostic value of brain-stem cavernous angioma(BCA).Methods 9 cases of BCA proved both surgically and pathologically with integrated clinical,MRI and pathological data were analyzed.Results The clinical attacks were divided into two types:the sudden and the resting.The MRI findings of BCA included:isointensity or hypointensity on T1WI(76.5%),isointensity or hyperintensity on T2WI(85.3%),heterogeneous mixed signal intensity on both T1WI and T2WI (36.2%),hypointense ring round angioma on T2WI (16.2%).On Gd-DTPA scanning,the lesions were slight enhancement or no enhancement in 8 cases.The shapes of lesions were round-like in most cases(86.6%),and typical moruloid or network in some cases(11.7%).The lesions localized in the midbrain in 3 cases,in the pons in 4,and in the medulla oblongata in 2.The histopathological findings included:composite pathological changes in most cades,elastic fibers in the angiomatous lacuna vasorum in 3 cases,visible drainage vein and supply artery in 2 cases.MRA showed hyperintensity around the angiomas in 5 cases.Conclusion MR imaging is of significant value in diagnosing BCA.
