        <title>Abstract</title>
        <p>A 78-year-old patient presented with shortness of breath after falling down. Transthoracic echocardiogram showed an extensive thrombus in the right atrium (RA), extensive thrombosis of the inferior vena cava (IVC), and abdominal aortic aneurysm (AAA). A magnetic resonance confirmed the thrombosis of the RA extending to the IVC, which was apparently fused to the abdominal aortic aneurysm (compression? erosion?). This case illustrates a severe and rare complication of a non-treated AAA. There probably was IVC erosion by the aortic aneurysm, leading to blood stasis and extensive thrombosis of the IVC and right cardiac chambers.</p>

      <title>Case Report</title>
      <p>A 78-year-old female patient presented with shortness of breath after falling down. She reported a history of systemic hypertension, stable coronary artery disease and abdominal aorta aneurysm undergoing clinical surveillance. The laboratory exams evidenced thrombocytopenia (22.000 mm<sup>3</sup>) with no other abnormalities. Transthoracic echocardiogram showed a heterogeneous hyper-echogenic mass at the right atrium, protruding into the right ventricle, highly mobile, suggestive of thrombus.<xref ref-type="bibr" rid="B1">1</xref><sup>-</sup><xref ref-type="bibr" rid="B3">3</xref> Extensive thrombosis of the inferior vena cava (IVC) (<xref ref-type="fig" rid="f1">Figure 1</xref>), and abdominal aorta aneurysm (AAA) of around 10 cm in diameter was also observed. The patient underwent thoracic, abdominal and pelvic computed tomography (CT). CT evidenced irregular, tortuous supra and infra-renal aortic aneurysm. There were paravertebral as well as ventral abdominal wall collaterals, indicating venous obstruction and signs of probable erosion of the IVC by the aneurysm. An aortic magnetic resonance was performed to better evaluate the aorta anatomy, which confirmed the extensive thrombosis of the IVC, in the segment related to the AAA, with extension of the thrombosis to the right cardiac chambers (<xref ref-type="fig" rid="f2">Figure 2</xref>). Anticoagulation therapy was contraindicated due to the thrombocytopenia and a discrete increase in platelet count was observed after corticosteroid and immunoglobulin therapy. The patient was discharged on request and died of sudden death ten days after dismissal.</p>

      <p>Right atrial masses are very rare findings. This case illustrates a severe and rare complication of a non-treated AAA. Enteric erosion is a well-known complication of aortic aneurysm or aortic dissection. Arteriovenous fistula has been described as a graft-related complication after AAA repair,<xref ref-type="bibr" rid="B4">4</xref> but to the best of our knowledge, this has not been reported for the native aorta and IVC. Unfortunately, this diagnosis was suspected in this patient by means of cardiovascular imaging techniques but not confirmed by anatomical pathological analysis.</p>

        <title>Resumo</title>
        <p>Uma paciente de 78 anos procurou o servi&#231;o de emerg&#234;ncia apresentando dispneia ap&#243;s sofrer queda da pr&#243;pria altura. O ecocardiograma transtor&#225;cico mostrou um extenso trombo no &#225;trio direito (AD), trombose extensa da veia cava inferior (VCI), e aneurisma de aorta abdominal (AAA). A resson&#226;ncia magn&#233;tica confirmou a trombose do AD estendendo-se at&#233; a VCI, a qual aparentemente apresentava fus&#227;o ao aneurisma da aorta abdominal (compress&#227;o? eros&#227;o?). Este caso ilustra uma complica&#231;&#227;o grave e rara de um AAA n&#227;o tratado. Provavelmente houve uma eros&#227;o da VCI pelo aneurisma da aorta resultando em estase sangu&#237;nea e trombose extensa da veia cava inferior e cavidades card&#237;acas direitas.</p>

        <title>Relato de Caso</title>
        <p>Paciente do sexo feminino, 78 anos, procurou o servi&#231;o de emerg&#234;ncia apresentando dispneia ap&#243;s sofrer queda da pr&#243;pria altura. A paciente apresentava hist&#243;rico de hipertens&#227;o arterial sist&#234;mica, doen&#231;a arterial coron&#225;ria cr&#244;nica e aneurisma de aorta abdominal em acompanhamento cl&#237;nico. Os exames laboratoriais demonstraram trombocitopenia (22.000 mm<sup>3</sup>) sem outras anormalidades. O ecocardiograma transtor&#225;cico mostrou uma massa heterog&#234;nea, hiper-ecog&#234;nica no &#225;trio direito, projetando-se at&#233; o ventr&#237;culo direito, com mobilidade significativa, sugestiva de trombo.<xref ref-type="bibr" rid="B1">1</xref><sup>-</sup><xref ref-type="bibr" rid="B3">3</xref> Tamb&#233;m foram observados trombose maci&#231;a da veia cava inferior (VCI) (<xref ref-type="fig" rid="f4">Figura 1</xref>) e um aneurisma da aorta abdominal (AAA) com aproximadamente 10 cm de di&#226;metro. A paciente foi submetida &#224; tomografia computadorizada (TC) tor&#225;cica, abdominal e p&#233;lvica. A TC demonstrou aorta de aspecto tortuoso e irregular, e aneurisma abdominal supra e infra-renal. Foram observados sinais de presen&#231;a de circula&#231;&#227;o colateral paravertebral, e tamb&#233;m abdominal ventral, indicando obstru&#231;&#227;o venosa e prov&#225;vel eros&#227;o da VCI pelo aneurisma. Foi realizada uma resson&#226;ncia magn&#233;tica da aorta para melhor avalia&#231;&#227;o da anatomia da aorta, a qual confirmou a trombose maci&#231;a da VCI, no segmento relacionado ao AAA, com extens&#227;o da trombose at&#233; as cavidades card&#237;acas direitas (<xref ref-type="fig" rid="f5">Figura 2</xref>).</p>

        <p>A terapia anticoagulante foi contraindicada devido &#224; plaquetopenia e um discreto aumento na contagem de plaquetas foi observado ap&#243;s terapia com corticosteroides e imunoglobulinas. A paciente recebeu alta a pedido e apresentou morte s&#250;bita dez dias ap&#243;s a alta hospitalar.</p>
        <p>Massas no &#225;trio direito s&#227;o achados muito raros. Este caso demonstra uma complica&#231;&#227;o grave e rara de um AAA n&#227;o-tratado.
