title: Hyperdense pericardial effusion in dermatomyositis and contrast induced nephropathy.
abstract: Pericardial involvement in dermatomyositis is rare and usually asymptomatic. In many instances, a diagnosis of pericardial involvement is not found until autopsy. Renal failure associated with connective tissue disorders can result in or potentially exaggerate pericardial inflammation. We report an unusual case of high-density pericardial effusion in a patient with dermatomyositis consequent upon contrast nephropathy as demonstrated by computed tomography. High-density pericardial effusion can be a result of an insidious cause such as pericardial inflammation rather than the more usual causes such as coronary or cardiac perforation.
