Clinical question: Rule out bleed, hydrocephalus or mass effect. Clinical question: Progressive dizziness, gait disturbance, urinary symptoms. Non-enhanced CT of brain:There is no evidence of intracranial hemorrhage, edema, mass-effect, midline shift or hydrocephalus. The cortical sulci and ventricular system appear slightly prominent however this may be still within normal range for patient's stated age of 87. Prior MRI examination indicates a small vessel disease however on this exam no definitive small vessel disease is detected.
Essentially unremarkable non-enhanced CT of brain.
