Idiopathic normal pressure hydrocephalus (iNPH) is a disease characterized by gait disturbance, cognitive impairment, and urinary incontinence. For those patients who do not respond to shunt surgery, it lacks objective radiologic findings for the diagnosis of shunt malfunction. Here we aimed to evaluate whether the Evans index and callosal angle change during a prospective long-term follow-up of patients with iNPH submitted to shunt surgery. ⋯ In this sample, patients with iNPH submitted to a programmable valve shunt had an increase in callosal angle concomitant to neurologic improvement. The Evans index did not change during follow-up.
