 There is an enhancing dural-based mass centered on the planum sphenoidale with extension towards the partially empty sella, measuring 15 x 11 x 20 mm. This mass abuts the optic chiasm and is isointense to gray matter on unenhanced T1 and T2 weighted images. Two small additional lesions are again noted over the right frontal convexity, measuring up to 9 mm, which on the prior CT examination displayed calcification. There is mild prominence of the lateral and third ventricles, as well as the sulci due to diffuse cerebral volume loss. There is persistent moderate soft tissue crowding at the foramen magnum with a somewhat pointed morphology of the cerebellar tonsils, which extend up to 7 mm inferior to the foramen magnum. There is unchanged prominence of extra-axial space posterior to the cerebellum. There is minimal nonspecific scattered cerebral white matter T2 hyperintensity. There is no acute infarct or midline shift. There are bilateral lens implants. There is a posterior disc-osteophyte complex at C3-4, which appears to indent the spinal cord.
1.The planum sphenoidale mass and smaller dural-based extra-axial masses over the right frontal convexity are stable in size, accounting for difference in technique, and likely represent meningiomas.2.Findings consistent with Chiari I malformation.3.No evidence of acute infarction or intracranial hemorrhage. 4.A posterior disc-osteophyte complex at C3-4, which appears to indent the spinal cord. Dedicated cervical spine imaging may be useful for further evaluation.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
