 Nonenhanced CT of brain:There is no evidence of interval new hemorrhage, edema, mass effect, midline shift or hydrocephalus. Very minimal residual blood in the subarachnoid space and the cortical sulci in the right frontal region is noted (axial image 18). This appears slightly smaller since prior examination from 7 -- 20 -- 2010. No evidence of residual subdural. No evidence of residual subdural. Small vessel disease of indeterminate age is again identified.A calcific lesion/mass measuring approximately 17 mm times 10 mm in size abuts the posterior aspect of the greater wing of right sphenoid bone. This shows no interval change since prior study. Finding may represent a small meningioma. An MRI examination is recommended for further evaluation of this lesion.
1.No evidence of residual subdural.2.Further decrease in the amount of minimal subarachnoid blood in the right frontal region.3.Small vessel disease of indeterminate age.4.Dural based calcific lesion posterior to the greater being the sphenoid. Likely meningioma. Follow-up with an MRI is recommended for exclusion of other possibilities.5.No evidence of new hemorrhage since prior exam.
