Cardiac Tamponade Rapidly Evolving Toward Constrictive Pericarditis and Shock as a First Manifestation of Noncardiac Cancer

Occult malignancy presenting as constrictive pericarditis

Metastatic tumour progression to the pericardium is generally characterised by an effusional pericarditis. It is extremely rare for tumour to metastasise to the pericardium and cause constrictive pericarditis in the absence of a pericardial effusion. We report the recent case of a patient who was referred to our centre with constrictive pericarditis. Following pericardectomy and histopathological analysis this was found to be secondary to an occult metastatic adenocarcinoma.

[Constrictive pericarditis as the first sign of lung cancer]

Symptoms such as cough and hemoptysis in patients with lung cancer can be the consequence of local bronchopulmonary disease, tumor growth that leads to compression of surrounding structures, distant metastases, diverse systemic effects (anorexia, asthenia, weight loss), or paraneoplastic syndromes associated with tumor production of certain hormones. Approximately 10% of patients are asymptomatic at diagnosis. We report the case of a 77-year-old man with dyspnea, pleuritic chest pain, and lower limb edema. The patient died within a few days. The cause of the clinical picture was constrictive pericarditis secondary to metastases from lung carcinoma.
