Clinical question: Preop stealth brain MRI. Signs and symptoms: Preop MRI. Pre- and post enhanced Stealth brain MRI:Examination demonstrates a right posterior parietal dural based paramedian well-demarcated and intensely enhancing mass consistent with meningioma. It measures 16 x 15 mm in transaxial dimensions which is slightly larger than prior exam from April 2015.Additionally there is a more laterally located right posterior parietal dural based enhancing tumor likely representing an additional focus of meningioma measuring at 12 x 9 mm in transaxial dimensions and without convincing evidence of significant change.Diffuse FLAIR hyperintensity in bilateral posterior parietal without associated mass effect and likely representing gliosis/encephalomalacia.
1.Dural base right posterior parietal paramedian meningioma measuring 16 x 15 in transaxial dimensions with subtle interval increased size.2.A more laterally located dural base right posterior parietal enhancing meningioma measures at 12 x 9 mm and without convincing change since prior exam.3.Extensive bilateral posterior parietal FLAIR hyperintensity without mass effect and suggestive of post treatment
