Diagram showing the patient's cerebrospinal fluid protein levels since first clinical deterioration until the final resolution of symptoms. The patient underwent tumor resection at age 18 years, 4.5 months following her first presentation with symptomatic communicating hydrocephalus. The cerebrospinal fluid protein level peaked at that time to 946 mg/dl (arrow). Following surgery, the protein level decreased gradually, reaching nadir (20 mg/dl) at 6 weeks. No further obstructive shunt malfunctions were noted
