Multifocal dural enhancement associated with temporal arteritis.
OBJECTIVE
To report the association of temporal arteritis and enhancement of the dura mater and temporalis muscle.


METHODS
A single patient with a complaint of headache and diplopia was studied.


METHODS
Academic medical center.


METHODS
A 69-year-old man presented with lateral rectus weakness, temporal artery tenderness, and an erythrocyte sedimentation rate of 65 mm/h.


METHODS
Biopsy of temporal artery and dura mater.


METHODS
Brain magnetic resonance imaging and pathological findings.


RESULTS
Magnetic resonance imaging of the brain showed multifocal dural enhancement and enhancement of the temporalis muscles. The temporal artery showed a necrotizing vasculitis and the dura showed perivascular inflammatory cells.


CONCLUSIONS
It is proposed that the temporal arteritis caused the multifocal dural enhancement and temporalis muscle enhancement on magnetic resonance imaging.
