Necrosis of the tongue and unilateral blindness in temporal arteritis.

While blindness is one of the typical clinical presentations of temporal arteritis, tongue necrosis, on the other hand, is an unusual complication of the disease. An 80 year old male patient presenting a sudden massive swelling of the tongue was admitted to the Hospital of Yverdon. The swelling rapidly progressed to a complete necrosis of the tongue within a few days. The clinical presentation, the dramatic evolution of the necrosis, and sudden unilateral blindness despite prompt treatment confirmed our diagnosis of temporal arteritis. However, all the examinations, including biopsy of the right temporal artery, remained non-specific for the disease. Our diagnosis was based on the unusual clinical presentation of the disease.
