Amyloid nodule and primary pulmonary lymphoma in the same lung: Radiologic-pathologic correlation of a rare combination

A 61-year-old man presented for lung cancer screening with low dose CT. A spiculated right apical nodule suspicious for primary lung malignancy and an indeterminate small basilar consolidation were identified. PET/CT was notable for increased FDG uptake in the basilar consolidation. Transthoracic ne...

Sumario:A 61-year-old man presented for lung cancer screening with low dose CT. A spiculated right apical nodule suspicious for primary lung malignancy and an indeterminate small basilar consolidation were identified. PET/CT was notable for increased FDG uptake in the basilar consolidation. Transthoracic needle biopsy of both lesions was performed which lead to pathologic diagnoses of pulmonary amyloid nodule for the apical nodule and pulmonary extramarginal zone lymphoma of the mucosa associate lymphoid tissue for the basilar consolidation. While incidental findings are common in lung cancer screening CT, exceedingly rare diagnoses or combinations or diagnoses may also be encountered. This case also underscores the value of pathologic diagnosis in cases of indeterminate lung nodules.
