Infiltrative cardiomyopathies are an increasingly recognized cause of heart failure warranting systematic evaluation. Given overlap of clinical and imaging findings among etiologies of infiltrative cardiomyopathies, comprehensive evaluation, including a history and physical examination, advanced cardiac imaging, and sometimes endomyocardial biopsy, is required for diagnosis. We report a case of infiltrative cardiomyopathy in which endomyocardial biopsy confirmed diagnosis of cobalt-induced cardiomyopathy. The novel teaching points highlighted by this case report include identification of heavy-metal toxicity as a cause of infiltrative cardiomyopathy, and the outline of a diagnostic approach and management for cobalt-induced cardiomyopathy.

Acetabular fractures after seizures are uncommon, and fewer than 30 cases are described in the literature. We present a patient with bilateral acetabular fractures after a seizure, with bilateral quadrilateral plate destruction and protrusio deformity. The patient underwent delayed staggered bilateral total hip arthroplasty 3 months after initial injury, with use of the femoral head as autograft for the protrusio deformities.
