RESUMO
INTRODUCTION: Pompe disease is a progressive and debilitating neuromuscular disorder that presents with a heterogeneous array of signs and symptoms including proximal muscle weakness, respiratory insufficiency, and/or elevated creatine kinase levels. It mimics other neuromuscular disorders, making its diagnosis challenging and often significantly delayed, thereby increasing morbidity and early mortality of the disease. METHODS: Three Pompe disease patients are discussed to highlight the challenging path to diagnosis and the common cluster of symptoms that could lead to timely and accurate diagnosis. RESULTS: After significant delays in diagnosis, Pompe disease was diagnosed on the basis of the pattern of proximal weakness. CONCLUSIONS: Suspicion and recognition of the characteristic symptoms of Pompe disease may improve both the timing and accuracy of the diagnosis, which will improve clinical outcomes and minimize disease progression.
