Clinical question: History of meningioma resected, evaluate recurrence or change. Signs and symptoms: None surveillance imaging. Pre and post enhanced brain MRI:No diffusion-weighted abnormalities.Examination demonstrates stable postoperative changes of a high convexity bilateral paramedian parietal craniotomy.Stable underlying uniform epidural thickening and enhancement since prior exam without convincing evidence of residual or recurrence of tumor.Small focus of underlying cortical and subcortical encephalomalacia/gliosis on the right since prior exam.The underlying superior sagittal sinus demonstrate no convincing evidence of signal abnormality or abnormal enhancement. The superior sagittal sinus however can be further assessed with dedicated MRV imaging.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and brain myelination otherwise and without abnormal parenchymal or leptomeningeal enhancement.Unremarkable images through the orbits, paranasal sinuses and mastoid air cells.
1.No diffusion weighted abnormalities.2.Stable postoperative changes of bilateral paramedian posterior parietal craniotomy with revisualization of a stable uniform dural/epidural thickening and enhancement and minimal right underlying parietal encephalomalacia as detailed.3.No detectable signal abnormality or abnormal enhancement of the underlying superior sagittal sinus.4.Stable and unremarkable pre and postcontrast enhanced brain MRI otherwise.
