Presentation
Bilateral temporal pain with visual impairment. Raised serum erythrocyte sedimentation rate (ESR) and serum C reactive protein (CRP). Follow up after steroid therapy.
Patient Data

Hypoechoic and diffused thickening of bilateral temporal arterial walls. The vessels are also tortuous.

FU US study 40 days later after steroid Rx.
Reduced hypoechoic and thickness of the temporal arterial wall. Vessel's course remains tortuous.
Pulse wave doppler demonstrates normal flow with a well-represented diastolic component.
Case Discussion
After steroid therapy (prednisone 50 mg/die) follow up study shows a substantial reduction of the arterial wall thickening and hypoechogenicity due to phlogosis.
Serum erythrocyte sedimentation rate (ESR) and serum C-reactive protein (CRP) lowered into normal ranges. Symptoms (temporal pain and visual impairment) reduced too.
Unfortunately, a biopsy was not performed, so diagnosis is to be considered presumptive.
