Clinical question: Evaluate for gray/white matter changes. Signs and symptoms: Vegetative state. Non-enhanced CT of brain:There is no evidence of intracranial hemorrhage, edema, mass effect, midline shift or hydrocephalus. The gray -- white matter differentiation is preserved. The cortical sulci, ventricular system and all CSF cisterns remain within normal. No detectable parenchymal volume loss. In comparison to the prior examination there is no evidence of interval change.Calvarium is intact.Limited views of the orbits, mastoid air cells and middle ear cavities are unremarkable.The visualization of fluid and soft tissue density within the sphenoid sinus with interval worsening since prior exam. This may be secondary to instrumentation an NG tube placement.Considering provided clinical date of follow-up with an MRI examination is recommended.
1.Essentially unremarkable CT of brain and unchanged since prior examination from 4 -- 26 -- 2010.2.Further follow-up with an MRI is recommended.
