Clinical question: History of craniotomy for meningioma. Evaluate for change. Signs and symptoms: Surveillance imaging. Pre and postcontrast enhanced brain MRI:No diffusion-weighted findings.Examination redemonstrates a homogeneously enhancing mass within the sella and basal cistern and with evidence of extension anteriorly along the planum sphenoidale and posteriorly along the dorsal aspect of the dorsum sella and clivus as well as bilateral cavernous sinuses. The transverse diameter of tumor at the level of cavernous sinuses measures 39 mm which is identical to prior study. The mass measures maximum of 5.5 mm along the dorsum aspect of clivus and with 17.7 mm craniocaudad size within the sella and basal cistern. The measurements are nearly identical to prior exam from 6-4-14 and consistent with patient's known meningioma. Bilateral internal carotid artery signal voids are identified and demonstrate no appreciable change since prior exam in the caliber which demonstrate no convincing evidence of decreased size.Unremarkable brain parenchyma in morphology and signal intensity on all MRI sequences and without detectable abnormal parenchymal or leptomeningeal enhancement.Unremarkable images through the orbits including axial fat-sat post enhanced series.Unremarkable images through the paranasal sinuses and bilateral mastoid air cells.
1.No acute intracranial process.2.Stable uniformly enhancing extra-axial mass within the sella, basal cistern, bilateral cavernous sinuses, along the dorsal aspect of clivus and minimally along the planum sphenoidale representing patient's known meningioma.3.Unremarkable pre and post enhanced brain MRI otherwise.
