Post craniotomy with aneurysm clipping. New symptoms and worsening headaches Non-infused head CT:Minimal area of low attenuation in the inferior aspect of right frontal lobe near the surgical site of clipped aneurysm may represent edema or encephalomalacia. This finding remains stable since prior exam. Expected postoperative changes of right-sided frontal craniotomy with interval improvement since prior study. Patchy nonspecific foci of subcortical low attenuation could represent small was ischemic disease. This appears a slightly more pronounced on the current exam than prior study. Recommend follow-up with an MRI. There is no evidence of cortical low attenuation to suggest ischemic cortical stroke.Widened subarachnoid space along the inner table of the skull in the right posterior frontal and parietal is highly suspected only small subdural collection. This is also a new finding since prior exam. There is very subtle effacement of cortical sulci secondary to finding.
1.Findings I do suspect that of small vessel disease of indeterminate age with interval worsening since prior study. Recommend follow-up with an MRI to exclude new subcortical ischemic strokes.2.A small CSF density subdural in the right posterior frontal -- parietal with minimal effacement of adjacent cortical sulci is a new finding since prior exam3.there is no evidence of any acute cortical stroke, hemorrhage, hydrocephalus or midline shift.
