Rhabdomyolysis is the breakdown of muscle cells leading to the release of cellular constituents such as electrolytes, enzymes and myoglobin. There is a broad differential diagnosis for this condition. In this report we describe a 65 year old male who presented with weakness, rhabdomyolysis, and acute kidney injury five days after receiving the seasonal flu vaccine. Laboratory investigations showed elevated creatine kinase and troponin-I, and extensive cardiac investigations yielded a diagnosis of myocarditis. The cause of his clinical picture is explored in this case report.
