The role of the head CT is controversial. It should obviously be performed in all patients with suspected elevations in intracranial pressure (ICP), however this is often a difficult clinical diagnosis. Approximately 50% of the patients in Durand’s study with focal neuro findings had CT abnormalities, whereas CT findings were seen in only 17% of patients without focal findings on exam (p < 0.01). Quagliarello and Scheld recommend getting CTs only in patients who are comatose, have papilledema or who have focal neuro deficits.
