%0 Journal Article %T Pompe's disease or type IIa glycogenosis %A Jacob Jos¨¦ Luiz Balthazar %A Leandro Rosiene Lisboa %A Parro Jr Adelino %J Arquivos Brasileiros de Cardiologia %D 1999 %I Sociedade Brasileira de Cardiologia - SBC %X This is the report of a five-month-old child presenting clinical evidence of Pompe's disease: severe hypotonicity, hyporeflexia and congestive heart failure. The ECG showed a short PR interval, the chest radiography disclosed marked cardiomegaly, and the echocardiogram revealed marked left ventricular hypertrophy - the most typical finding of this disease. A skeletal muscle biopsy led to final diagnosis, because in the histopathologic study marked increased glycogen accumulation was evident. Death occurred two months after symptom onset. %U http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0066-782X1999001100004
