[Solitary pulmonary nodule]

Abstract

Primary pulmonary amyloidosis is rare. Three patterns of involvement have been described: tracheobronchial, nodular and diffuse parenchymal. The nodular parenchymal amyloid deposits are often multiple, much less common focal. We hereby present a case of a 70 year old patient, a former smoker, with coincidentally diagnosed solitary, pulmonary nodule, a rather common finding in CT. The list of differential diagnosis is long, as shown above, the amyloidosis is a quite uncommon cause, but it should be kept in mind.
