Presentation An 83-year-old man presented for headache and altered mental status. Four days prior, he underwent endoscopic sinus surgery for nasal polyps. Over the two previous days, he gradually developed a headache and was brought to the emergency department when his wife noted mild confusion and generalised weakness. His examination was notable for a heart rate of 101 beats per minute, clear nasal discharge, meningismus and confusion to the date with generalised weakness. A lumbar puncture revealed cloudy cerebrospinal fluid (CSF) with a white blood cell count of 3519x10ˆ9/L (95% neutrophils). A CT scan of the head was obtained (figure 1).
What is the appropriate next step in management?
Obtain MRI of the brain to localise ischaemic damage.
Administer broad-spectrum antibiotics, including pseudomonal coverage.
Consult otolaryngology to arrange functional endoscopic sinus surgery for CSF leak closure.
Consult neurosurgery for surgical decompression of mass lesion(s).
