Figure 1a.MRI brain scans. gadolinium enhanced T1-weighted coronal brain MRI
of the patient on admission. In the left parietal lobe there is an area of low
signal with rim enhancement following contrast, consistent with a cerebral
abscess. On the right there is basal meningeal enhancement with evidence of a
subdural empyema.

scan). Three lesions in both hemispheres are demonstrated, two with well
demarcated abscess capsules and surrounding areas of high signal corresponding
to vasogenic oedema
