Case Based Review


We describe an 11-year-old girl, diagnosed with juvenile polymyositis (JPM), who developed right ureteral obstruction secondary to necrosis. We emphasize the dilemmas regarding optimal timing for surgical intervention and medical treatment. Vascular involvement, which could be a part of juvenile dermatomyositis, may also be a feature of JPM. We discuss the association between vasculopathy and ureteral necrosis and review the literature regarding similar conditions. Whether the ureteral necrosis is a specific feature of vasculopathy, or a result of visceral calcinosis, needs to be further explored.
