Leg Pain From Periostitis as the First Clinical Manifestation of Large-Vessel Vasculitis: A Case Report.

Abstract

We report a case of a 47-year-old woman with isolated periostitis of the lower leg as a first manifestation of large-vessel vasculitis. The diagnosis was first suspected when a second magnetic resonance imaging of the lower leg approximately 4 months after onset of shin pain showed edema near intramuscular vessels. Isolated periostitis is a very rare skeletal manifestation of systemic vasculitis and easily could be misdiagnosed. This case demonstrates that maintaining a broad differential diagnosis for a common presenting complaint such as localized leg pain is imperative. V.
