    <p>Um homem de 52 anos estava sendo submetido a quimioterapia de primeira linha com pemetrexedo devido a um adenocarcinoma de pulm&#227;o hilar direito em est&#225;gio IV com prov&#225;veis met&#225;stases pleurais, peric&#225;rdicas, hep&#225;ticas e &#243;sseas. Durante o acompanhamento, nenhuma evid&#234;ncia de progress&#227;o da doen&#231;a foi encontrada. Quatro anos depois, uma tomografia computadorizada de t&#243;rax de acompanhamento documentou um realce nodular heterog&#234;neo do mioc&#225;rdio do ventr&#237;culo esquerdo (VE) (<xref ref-type="fig" rid="f01">Figura 1A</xref>), as les&#245;es restantes estavam sobrepostas. Ele n&#227;o apresentava sintomas cardiovasculares e o exame cl&#237;nico era normal. A ecocardiografia transtor&#225;cica (<xref ref-type="fig" rid="f01">Figura 1B</xref>) e a resson&#226;ncia magn&#233;tica card&#237;aca (Figuras 1C-E) revelaram diversas massas endomioc&#225;rdicas bem arredondadas, algumas das quais multilobuladas, por vezes com extens&#227;o quase transmural. As les&#245;es distribuem-se predominantemente ao longo da parede inferoseptal do VE, parede &#237;nferolateral, parede anterolateral, parede anterior e lado direito do septo interventricular. Essas les&#245;es apresentavam caracter&#237;sticas de sinal heterog&#234;neas, sendo predominantemente hiperintensas nas imagens ponderadas em T1, hipointensas nas imagens ponderadas em T2 com halo perif&#233;rico de hiperintensidade, mostrando realce precoce heterog&#234;neo e tardio intenso por gadol&#237;nio; e capta&#231;&#227;o anormal de fluorodesoxiglicose em PET/CT com 18F-FDG (<xref ref-type="fig" rid="f01">Figura 1F</xref>).</p>

    <p>Assim, embora as massas card&#237;acas n&#227;o tenham sido biopsiadas, o seu aspecto imagiol&#243;gico foi preocupante para a progress&#227;o tumoral. Decidiu-se adicionar pembrolizumab ao pemetrexedo. Atualmente, o paciente encontra-se vivo h&#225; mais de 18 meses ap&#243;s o diagn&#243;stico de met&#225;stases card&#237;acas.</p>

      <p>A 52-year-old male was undergoing first-line chemotherapy with pemetrexed due to a stage IV right hilar lung adenocarcinoma with likely pleural, pericardial, liver, and bone metastases. During follow-up, no evidence of disease progression was found. Four years later a follow-up chest CT scan documented a nodular heterogeneous enhancement of the left ventricular (LV) myocardium (<xref ref-type="fig" rid="f01001">Figure 1A</xref>), the remaining lesions were overlapping. He had no cardiovascular symptoms and clinical examination was unremarkable. Transthoracic echocardiography (<xref ref-type="fig" rid="f01001">Figure 1B</xref>) and cardiac MRI (Figures 1C-E) revealed several well-rounded endo-myocardial masses, some of which multilobulated sometimes with almost transmural extension. The lesions are predominantly distributed along the LV inferoseptal wall, inferolateral wall, anterolateral wall, anterior wall, and right side of the interventricular septum. These lesions had heterogeneous signal characteristics, being predominantly hyperintense on T1-weighted images, hypointense on T2-weighted images with a peripheral halo of hyperintensity, showing early heterogeneous and late intense gadolinium enhancement; and abnormal uptake of fluorodeoxyglucose in a 18F-FDG PET/CT (<xref ref-type="fig" rid="f01001">Figure 1F</xref>).</p>

      <p>Thus, though the cardiac masses were not biopsied, their imagiological appearance was concerning for tumor progression. It was decided to add pembrolizumab to pemetrexed. Currently, the patient is alive over 18 months after the diagnosis of cardiac metastases.</p>
      <p>Multiple cardiac metastases from non-small cell lung cancer are extremely rare and often go undiagnosed until postmortem. The prognosis is uniformly poor, with few long-term survivors.<sup><xref ref-type="bibr" rid="B1">1</xref></sup></p>
