[Glucocorticoid sensitive bilateral leg swelling in an 85-year-old woman presenting with polymyalgia rheumatica: A case report].

Introduction: Polymyalgia rheumatica (PMR) can be associated with distal swelling indicating an associated RS3PE syndrome. We report a case of PMR associated with oedema of the lower limbs, which resolved rapidly under glucocorticoid therapy.
Case Report: A 85-year-old woman presented with a 4 month history of PMR responding to the 2012 EULAR/ACR classification criteria. Examination of the lower limbs revealed pitting oedema bilaterally up to the knees, with mild erythema and warmth. Hypoalbuminemia (30g/L) was present. There was no cardiac, renal or hepatic cause to explain leg swelling. FDG-PET/CT demonstrated increased metabolism in the periarticular area of shoulders and hips. There was no sign of aortitis or neoplasia. Under treatment with prednisone 10mg/day leg swelling disappeared concomitantly to a weight loss of 8kg within 8days.
Conclusion: This case, the first to report leg swelling of inflammatory origin in the context of PMR, could indicate an increased vascular permeability caused by inflammation in the elderly.
