    <p>Um homem de 18 anos foi atendido em nosso ambulat&#243;rio com uma hist&#243;ria de tr&#234;s meses de dispneia progressiva e tosse improdutiva. Os sintomas estavam presentes mesmo em repouso, e a atividade f&#237;sica apresentava limita&#231;&#227;o severa. O diagn&#243;stico era de glicogenose tipo IV, e tinha sido obtido desde os tr&#234;s anos de idade, quando desenvolveu hepatomegalia e disfun&#231;&#227;o hep&#225;tica leve. Naquele momento, o exame histopatol&#243;gico mostrou fibrose de grau dois, juntamente com numerosos dep&#243;sitos intracitoplasm&#225;ticos positivos para &#225;cido peri&#243;dico de Schiff (PAS) resistentes &#224; diastase. A partir de ent&#227;o, sua fun&#231;&#227;o hep&#225;tica permaneceu est&#225;vel, e ele persistiu assintom&#225;tico.</p>
    <p>Seus exames de avalia&#231;&#227;o laboratorial de rotina estavam normais; no entanto, o eletrocardiograma (ECG) basal (<xref ref-type="fig" rid="f1">Figura 1</xref>) mostrou sinais de hipertrofia ventricular esquerda. Ele foi submetido a resson&#226;ncia magn&#233;tica cardiovascular (RMC), que apresentou hipertrofia assim&#233;trica com predom&#237;nio no septo interventricular (<xref ref-type="fig" rid="f2">Figura 2</xref>), assim como realce tardio em um padr&#227;o irregular e multifocal (<xref ref-type="fig" rid="f3">Figura 3</xref>). Iniciou-se, ent&#227;o, terapia m&#233;dica para insufici&#234;ncia card&#237;aca. O paciente agora est&#225; assintom&#225;tico e mant&#233;m acompanhamento regular em nosso ambulat&#243;rio.</p>

    <p>Pessoas com glicogenose tipo IV em sua forma cl&#225;ssica apresentam doen&#231;a hep&#225;tica grave, com r&#225;pida progress&#227;o para cirrose durante a inf&#226;ncia.<xref ref-type="bibr" rid="B1"><sup>1</sup></xref> No entanto, um pequeno grupo de indiv&#237;duos afetados pode apresentar disfun&#231;&#227;o hep&#225;tica mais leve, que n&#227;o avan&#231;a para doen&#231;a hep&#225;tica terminal.<xref ref-type="bibr" rid="B1"><sup>1</sup></xref><sup>,</sup><xref ref-type="bibr" rid="B2"><sup>2</sup></xref> Nosso paciente teve o diagn&#243;stico de glicogenose tipo IV aos tr&#234;s anos de idade, mas n&#227;o desenvolveu cirrose a partir de ent&#227;o.</p>
    <p>Embora se saiba que algumas doen&#231;as de armazenamento de glicog&#234;nio imitam a cardiomiopatia hipertr&#243;fica (p. ex., doen&#231;a de Danon e s&#237;ndrome do PRKAG2),<xref ref-type="bibr" rid="B3"><sup>3</sup></xref> esse padr&#227;o de envolvimento card&#237;aco foi relatado apenas duas vezes<xref ref-type="bibr" rid="B2"><sup>2</sup></xref><sup>,</sup><xref ref-type="bibr" rid="B4"><sup>4</sup></xref> em casos de glicogenose tipo IV.

No entanto, a RMC n&#227;o havia sido realizada para melhor caracterizar o envolvimento card&#237;aco.</p>

Realce tardio &#233; observado em mais de 50% dos casos de cardiomiopatia hipertr&#243;fica e geralmente exibe um padr&#227;o mesoc&#225;rdico multifocal.<xref ref-type="bibr" rid="B3"><sup>3</sup></xref><sup>,</sup><xref ref-type="bibr" rid="B5"><sup>5</sup></xref> Outros tipos de cardiomiopatias n&#227;o isqu&#234;micas, por outro lado, em geral n&#227;o apresentam realce tardio at&#233; os est&#225;gios finais da doen&#231;a.<xref ref-type="bibr" rid="B3"><sup>3</sup></xref> </p>

      <p>An 18-year-old male patient presented to our ambulatory services due to a 3-month course of progressive dyspnea and non-productive cough. Symptoms were present even at rest, and he exhibited severe limitation at physical activity. He had a diagnosis of glycogen storage disease (GSD) type IV attained by liver biopsy since three years of age, when he developed hepatomegaly and mild hepatic dysfunction. At the time, histopathological examination showed grade 2 fibrosis along with numerous intracytoplasmic PAS-positive deposits that were resistant to diastase. Thenceforth, his liver function remained stable, and he persisted otherwise asymptomatic. His physical examination was unremarkable, and routine laboratory evaluation was within the normal ranges. However, his basal ECG (<xref ref-type="fig" rid="f4">Figure 1</xref>) showed signs of left ventricular hypertrophy. He was submitted to a cardiovascular magnetic resonance (CMR), which showed asymmetrical hypertrophy with predominance in the interventricular septum (<xref ref-type="fig" rid="f5">Figure 2</xref>). Late gadolinium enhancement (LGE) was present in a patchy, multifocal pattern (<xref ref-type="fig" rid="f6">Figure 3</xref>). Medical therapy for heart failure was initiated; the patient is now asymptomatic and maintains regular follow-up in our ambulatory.</p>

          <title>The baseline ECG shows sinus rhythm with a heart rate of 62 bpm. There are sings of left ventricular hypertrophy with deep asymmetrical T wave inversion. Also, there are narrow Q waves in leads V 4&#8211;V 6, I, and aVL, along with counterclockwise rotation; such findings are likely caused by a prominent septal depolarization vector.</title>

      <p>Patients with classic GSD type IV have unrelenting liver disease with fast progression to cirrhosis during childhood;<xref ref-type="bibr" rid="B1"><sup>1</sup></xref> however, a small subset of affected individuals may present with milder hepatic dysfunction that does not advance to end-stage liver disease.<xref ref-type="bibr" rid="B1"><sup>1</sup></xref><sup>,</sup><xref ref-type="bibr" rid="B2"><sup>2</sup></xref> Accordingly, our patient had the diagnosis of GSD type IV by three years of age, but did not develop cirrhosis afterwards.</p>
      <p>Although some glycogen storage diseases are known to mimic hypertrophic cardiomyopathy (e.g., Danon disease, PRKAG2 syndrome),<xref ref-type="bibr" rid="B3"><sup>3</sup></xref> this pattern of heart involvement had been reported only twice<xref ref-type="bibr" rid="B2"><sup>2</sup></xref><sup>,</sup><xref ref-type="bibr" rid="B4"><sup>4</sup></xref> in cases of type IV GSD. Both patients coursed with asymptomatic myocardial hypertrophy revealed by echocardiogram. However, the CMR had not been performed to better characterize the cardiac involvement.</p>
      <p>Our patient's findings are consistent with the classical description of hypertrophic cardiomyopathy.<xref ref-type="bibr" rid="B3"><sup>3</sup></xref><sup>,</sup><xref ref-type="bibr" rid="B4"><sup>4</sup></xref> Most phenotypes of the disease are characterized by asymmetrical heart involvement, and the interventricular septum is commonly affected. Nevertheless, some patients may present with hypertrophy predominance in other areas of the heart, or even with a symmetrical pattern. LGE is found in more than 50% of cases of hypertrophic cardiomyopathy and typically displays a mid-wall speckled pattern;<xref ref-type="bibr" rid="B3"><sup>3</sup></xref><sup>,</sup><xref ref-type="bibr" rid="B5"><sup>5</sup></xref> by contrast, other types of non-ischemic cardiomyopathies commonly lack LGE until the late stages of the disease.<xref ref-type="bibr" rid="B3"><sup>3</sup></xref> </p>
      <p>Storage diseases reported to mimic hypertrophic cardiomyopathy often present with massive left ventricular hypertrophy. Whereas concentric hypertrophy is the most common presentation of Fabry disease and Danon disease, our case coursed with predominant septal involvement. This pattern is usually caused by Pompe disease and PRKAG2 syndrome, sometimes with outflow tract obstruction.<xref ref-type="bibr" rid="B3"><sup>3</sup></xref><sup>,</sup><xref ref-type="bibr" rid="B5"><sup>5</sup></xref> In such cases, mid-ventricular LGE is an early finding, which may be restricted to the inferolateral walls; as the disease progresses, a diffuse pattern is more likely to be found.<xref ref-type="bibr" rid="B3"><sup>3</sup></xref> </p>
