Clinical question: Preoperative Stealth brain MRI. Signs and symptoms: Craniotomy CCM resection. Pre-and post enhanced Stealth brain MRI:Examination demonstrates a tiny focus of enhancement in the lower posterior pons consistent with a tiny cavernoma. This finding demonstrated susceptibility signal changes on prior MRI and enhancement without interval change. It measures approximately 1.9 mm in size.Examination also redemonstrated a right frontal cavernoma in the cingulate gyrus measuring approximately at 11 times 12-mm in transaxial dimensions. This lesion demonstrates no surrounding encephalomalacia or edema however hemosiderin staining is present similar to prior exam. Ventricular system are within normal size and the maintained midline. Diffuse punctate foci of T2 hyperintensity in the subcortical and periventricular white matter remains stable since prior exam.Note should be made that this exam he is performed as a surgical guidance and is not a true diagnostic study.
1.Right anterior frontal cingulate gyrus cavernoma without change since prior exam.2.Inferior posterior pontine enhancing cavernoma measuring1.9 mm without change since prior exam.3.Stable scattered subcortical and periventricular foci of flair hyperintensity since prior exam.
