Alveolar Septal Pulmonary Amyloidosis: A Case Report

ABSTRACT

Primary pulmonary amyloidosis is a rare disease, and is classified as either tracheobronchial or parenchymal ; the latter is also divided into nodular and diffuse alveolar septal forms. The alveolar form is extremely rare and usually produces reticular and nodular opacities. We describe a case of alveolar septal pulmonary amyloidosis manifested as multiple small nodules on chest radiograph and disseminated micronodules mainly in centrilobular and subpleural location without reticular opacities, on HRCT.
