ABSTRACT

Diagnosis: Epidural brain abscess, CNS

History: 9 year old boy presented to the Emergency Department with a head ache and "swollen eyes". The patient had been treated for a sinus infection for 14 days but his head ache and eye swelling were getting worse despite finishing his course of antibiotics.

Findings: Non contrast CT demonstrated an isodense to grey matter-extraaxial, intracranial fluid collection that followed the convexity of the frontal cranium. It did not enhance after contrast - but showed rim enhancement of the displaced dura. There were numerous foci of air within it. Additionally, there was extensive paranasal sinus opacification with air fluid levels, most prominent in the left maxillary sinus and in frontal and ethmoid sinuses bilaterally. There are bilateral inflammatory changes seen in the preseptal orbital tissues that extended over the zygomatic arches bilaterally. MR imaging shows an epidural fluid collection with these signal characteristics: Iso to grey matter on T1, Hyperintense to grey matter on T2, FLAIR and DWI with low signal on ADC mapping. The child could not remain still enough for contrast enhanced MR images.
