A 54-year-old man with a history of type 1 diabetes mellitus and hyperthyroidism presented with typical symptoms of pericarditis after an episode of flu-like symptoms. His electrocardiogram revealed diffuse ST-T segment elevation not confined to an arterial territory. Plasmatic levels of cardiac troponin remained within normal values. Treatment with nonsteroidal anti-inflammatory drugs was initiated, but he presented with recurrent symptoms and progressive dyspnea several weeks later. Further evaluation revealed a history of frequent purulent nasal discharge. Urine analysis demonstrated microhematuria. Echocardiography revealed a thickened pericardium without effusion, augmented respiratory variation of mitral inflow (Fig. 1A), normal medial peak E0 velocities (Fig. 1B), and abnormal septal motion during diastole (septal bounce). Cardiac magnetic resonance imaging showed marked pericardial thickening on cine, T1-, T2-weighted, and delayed enhancement (DE) imaging (Fig. 1, D-F), with diastolic septal bounce on cine imaging (see Videos 1 and 2; view videos online) compatible with constriction.1 On T2weighted and DE imaging, the hyperintense visceral and parietal pericardium were clearly discernable. Midwall linear hyperintensity in the basal inferolateral segments complemented the diagnosis of acute perimyocarditis. Endomyocardial biopsies did not show active myocarditis or granuloma formation on histology. Additional immunohistological analysis revealed borderline leukocyte

infiltration (13 CD45-positive inflammatory cells per mm2; Fig. 1C) and an increased parvovirus-B19 viral load (319 copies per microgram DNA) in polymerase chain reaction assay. A serology test showed the presence of perinuclearantineutrophil cytoplasmic antibody (ANCA) (titer: 1/ 128) confirmed with proteinase 3-capture enzyme-linked immunosorbent assay and a marked increased soluble interleukin-2 (5587 pg/mL), consistent with granulomatosis with polyangiitis (formerly known as Wegener granulomatosis). Cardiac involvement is not uncommon in systemic inflammatory diseases.2 Pericardial involvement has been especially described in patients with granulomatosis with polyangiitis.3 Evolution to constrictive pericarditis is a feared and rare complication; it has been attributed to recurrent or incessant episodes of pericarditis.4 Development of constrictive pericarditis after a first episode of peri(myo) carditis has not previously been described in patients with granulomatosis with polyangiitis. Our case suggests a parvovirus B-19 infection triggered perimyocarditis. It highlights a secondary exaggerated inflammatory response possibly due to an underlying ANCA vasculitis resulting in early evolution to constrictive pericarditis. Antibodies directed against proteinase 3 (proteinase 3-ANCA) and myeloperoxidase (myeloperoxidase-ANCA) are highly specific for the diagnosis of systemic vasculitis. However, they have been found as an epiphenomenon of acute parvovirus B-19 infection.5 Although we do not have repeat antibody titers to confirm its biochemical diagnosis, clinical symptoms are highly suspect for a systemic autoimmune disease in this case of granulomatosis with polyangiitis. After immunosuppressive therapy with mycophenolate mofetil and corticosteroids his symptoms subsided with improvement of constrictive physiology on echocardiography. Nonetheless, the bouncing septum and increased pericardial thickening on cardiac magnetic resonance remained.

Visceral (arrows) and parietal pericardium (arrows) show increased signal intensity on (E) T2-weighted and (F) DE images, with focal linear, midwall hyperintensity on the DE images, compatible with acute perimyocarditis.
