The seven categories of HPH aetiology are italicized. Space-occupying lesions include 59 patients with malignant brain tumours, 4 patients with benign intraventricular cysts and 4 patients with giant basilar aneurisms. IIH=idiopathic intracranial hypertension. Postinfectious include patients with hydrocephalus secondary to meningitis. Juvenile include children with a demonstrated increased intracranial pressure without any structural pathology on MRI. One patient did not fit into any of these categories.
AB prophylaxis, whether the patient receives antibiotic prophylaxis intraoperatively or is in a covering treatment; HPH, high-pressure hydrocephalus; NPH, normal-pressure hydrocephalus; Stenosis, aqueductal stenosis.
