We present the heart of a 38-year-old man with paraplegia due to a remote traumatic spinal cord injury. In the 20 years following his injury, he experienced chronic decubitus ulcers, osteomyelitis, neurogenic bladder, malnutrition, and urinary tract infections. He was admitted to the hospital with septic shock secondary to multiple decubitus ulcers and osteomyelitis and expired after a two-month hospitalization. At autopsy, there was marked replacement of left ventricle and interventricular septal myocardium by gritty, firm, yellow-white tissue. Microscopic examination demonstrated a remote infarct with marked dystrophic calcification and unexpected amyloid deposition. This example demonstrates the extraordinary extent to which dystrophic calcifications can replace myocardium and highlights multiple potential etiologies of myocardial calcifications. Of note, this is the first report documenting myocardial calcification as a complication of remote, non-iatrogenic trauma. The role of the amyloidosis in the development of calcification is unclear, but a contributory effect cannot be excluded.
