Amyloidosis presenting as pulmonary infarcts: a case report.

Amyloidosis is a multisystem disease characterized by extracellular deposition of complex protein-polysaccharide in a β-pleated configuration. The imaging features in the thorax are well described and are traditionally divided into tracheobronchial, nodular parenchymal, and diffuse alveolar septal subtypes. We describe an unusual case of pulmonary amyloidosis presenting with hemoptysis as a result of pulmonary infarcts related to vascular deposition. With this case, we show that amyloidosis should be considered (along with embolic disease) when vascular insults (infarcts) are seen in multiple vascular territories.
