Diagnosis and management of temporal arteritis: a review and case report.

Temporal arteritis is an insidious disease which, if not recognized and treated with high-dosage oral prednisone or intravenous prednisolone, can result in unilateral or even total blindness due to anterior ischemic optic neuropathy (AION) or closure of the central artery of the retina. Unfortunately, the symptoms and clinical signs of temporal arteritis mimic those of a number of other conditions including angle-closure glaucoma, hypertension, migraine, trigeminal neuralgia, temporomandibular joint syndrome, carotid artery occlusive disease, Foster-Kennedy syndrome, and nonarteritic AION. When a patient complains of a severe pain in the temporal region, along with scalp tenderness and a feeling of malaise or depression--with or without episodes of transient loss of vision--he or she should be referred for a diagnostic work-up which includes an erythrocyte sedimentation rate and a temporal artery biopsy. We present here a review of the recent literature concerning temporal arteritis, followed by a report of an unusual case in which high-dosage prednisone therapy was effective in relieving the patient's symptoms and lowering the sedimentation rate in spite of a negative temporal artery biopsy.
