A 32-year-old, right-handed, female patient with a right glomus jugulare paraganglioma was undergoing stereotactic radiation therapy (including the trigeminal ganglion in Meckel's cave) (fig. 1) and received oral dexamethasone (16 mg daily).
Head CT, axial view. a A focal hypodensity within the right temporal lobe is observed on admission. b On the fifth day after admission, bilateral worsening of the hypodensities in the orbital frontal, cingular, insular and temporal regions in spite of isolated acyclovir treatment occurred.

A CT scan showed a new focal hypodensity within the right temporal lobe (fig. 2a), but the paraganglioma remained unchanged. A CT scan showed larger bilateral hypodensities in the orbital frontal, temporal, insular and cingular regions (fig. 2b).
