Cisto de pericárdio: uma apresentação incomum

Abstract

Tumores e cistos do coração são raros. A proposta deste artigo é apresentar um caso de cisto pericárdico com aspecto radiográfico atípico, diagnosticado por ecocardiograma transtorácico. A paciente referia sensação de desconforto no hemitórax esquerdo e observou-se, nas radiografias do tórax, a presença de massa contígua ao coração no seio cardiofrênico direito. Os autores também fazem uma sucinta revisão do assunto.

Cisto pericárdico gigante: relato de caso

“…Occasionally, they can alter the cardiovascular hemodynamics and/or the pulmonary expansion producing signs and symptoms that can mimic tricuspid stenosis, pulmonary stenosis, or constrictive pericarditis [3,4]. In the present case report, the compression of the mediastinal structures typically caused the symptoms of dyspnea, thoracic pain, and cough due to the unusual large size of the cyst.…”

“…However, the diagnosis can be especially difficult when the lesion occur outside their typical location at the right cardiophrenic angle; or more rarely, as in the case reported here, in which the lesion was extensive and confluent with mediastinal structures, and followed by symptomatology [1,3].…”

“…Other cysts should be differentiated, such as interstitial bronchogenic cyst and lymphangiomas, besides other diseases, such as diaphragmatic hernia, and aneurysms of the heart or great vessels aneurysms [2,3].…”

“…The most common finding on roentgenograms is a round homogeneous radiodense lesion at the cardiophrenic angle, two thirds being found on the right [3]. These finds are enough to the diagnostic but confirmation may be obtained by twodimensional echocardiography, computed tomography, or nuclear magnetic resonance (NMR) [1][2][3]. The aim of the present case report is to describe a case of a successful surgical excision of a giant pericardial cyst.…”

“…Chest pain, Dyspnea, or paroxysmal tachypnea, are symptoms found in 25% to 30% of the patients [1,2]. The most common finding on roentgenograms is a round homogeneous radiodense lesion at the cardiophrenic angle, two thirds being found on the right [3]. These finds are enough to the diagnostic but confirmation may be obtained by twodimensional echocardiography, computed tomography, or nuclear magnetic resonance (NMR) [1][2][3].…”
