Transient constrictive pericarditis following coxsackievirus A4 infection as a rare cause of acute mediastinitis: A case report

[Potential of Magnetic Resonance Imaging in Diagnostics of Transient Constrictive Pericarditis]

The article addresses the diagnostic criteria based on magnetic resonance imaging (MRI) in transient constrictive pericarditis (TCP), a rare form of constrictive pericarditis characterized by temporary signs of constriction. Constrictive pericarditis evident as myocardial thickening and fibrosis results in impaired diastolic filling and can manifest itself with symptoms similar to those of other pathologies, such as restrictive cardiomyopathy. The article presents two clinical cases of TCP, where the role of MRI in the diagnosis and monitoring of patients is highlighted. For diagnostics, echocardiography and MRI were used along with laboratory tests, including the tests for inflammation markers and troponin. MRI allows not only to visualize changes in the pericardial structure but also to monitor changes in the condition, which is important for choosing the treatment tactics. In both cases, symptoms were successfully resolved, and the patients' condition was normalized with drug therapy. The results highlight the importance of early diagnosis and proper management tactics to prevent irreversible changes in the pericardium and heart failure.
