Multifocal dural enhancement associated with temporal arteritis.

OBJECTIVE

To report the association of temporal arteritis and enhancement of the dura mater and temporalis muscle.

DESIGN AND

METHODS

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

SETTING

Academic medical center.

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

INTERVENTION: Biopsy of temporal artery and dura mater.

MAIN OUTCOME MEASURES: 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.

CONCLUSION

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