This table summarises the frequency of radiology features reported on admission CT scans, final CT scans of the 4 patients who died before 3 week MRI (Early deaths), on 3 week MRI, and early deaths combined with MRI findings (Overall). The associations between radiology features and poor 6 month clinical outcome are indicated. Data are presented as number (percent) of patients.
HCP was treated with EVDs or VPS,
4 of these patients had a dry tap and the air encephalogram could not be definitively performed, and 1 patient was thought to have bacterial meningitis and underwent an immediate shunt procedure
Only 38 patients received contrast
infarcts < 10 days old
infarcts > 14 days old,
combination of infarcts < 10 days and >10 days old
