Abstract
Tubular aggregate myopathies comprise a rare group of disorders with characteristic pathological findings and heterogeneous phenotypes, including myasthenic syndrome. We describe a patient with tubular aggregate myopathy who presented with fatiguable weakness improving with pyridostigmine, respiratory involvement and possible cardiac manifestations. We highlight the utility of muscle biopsy in atypical myasthenic syndrome.
